* mount/fuse: Make event-history feature configurableKrutika Dhananjay2017-09-243-14/+42
| | | | | | | | | | | | | | | | | | | | | | ... and disable it by default. This is because having it disabled seems to improve performance. This could be due to the lock contention by the different epoll threads on the circular buff lock in the fop cbks just before writing their response to /dev/fuse. Just to provide some data - wrt ovirt-gluster hyperconverged environment, I saw an increase in IOPs by 12K with event-history disabled for randrom read workload. Usage: mount -t glusterfs -o event-history=on $HOSTNAME:$VOLNAME $MOUNTPOINT OR glusterfs --event-history=on --volfile-server=$HOSTNAME --volfile-id=$VOLNAME $MOUNTPOINT Change-Id: Ia533788d309c78688a315dc8cd04d30fad9e9485 BUG: 1467614 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com>
* fuse/readdirp: Remove need_lookup from fuse_readdirp_cbkSusant Palai2017-09-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | background: Various xlators used to populate their ctx, on an explicit lookup. That means without a lookup, the translator will have either null or stale data to function. E.g. dht would depend on lookup to create linkto files on the correct node/hashed subvol, afr would rely on this lookup to heal pending data/metadata etc. So to complete above actions a lookup used to be issued on files, even their inode was populated on a readdirp_cbk. This was done by setting the need_lookup flag on all the files those were read on readdirp fop. We tried a small test on "ACL client". For listing 50k files on root itself, it took around 50seconds with readdirp enabled while the same operation took 5-6 seconds with readdirp disabled. Both the times md-cache was enabled. We observed that on the 1st test case (readdirp enabled), post readdirp a getxattr is done. The number of getxattr depends on the number of acl xattrs (I saw requests on these two: system.posix_acl_default, system.posix_acl_access). Since need_lookup flag is set, during fuse_resolve a nameless lookup is executed on the inode(getxattr being inode operation, hence the nameless lookup). Since md-cache does not serve nameless lookup, a network hop is needed for each file, costing the time. With readdirp disabled, the getxattrs are served from md-cache itself(note: we are discussing the 2nd attempt of ls -l use case). _Current affairs around need of lookup for a file to populate it's ctx_: For the xlators on client stack we discussed quite extensively about the need for a lookup fop post readdirp in all three cluster translators - afr, EC and dht. EC and dht don't really need a nameless lookup post readdirp. For afr too, the need for lookup was negated with patch (http://review.gluster.org/6010 - AFRV2), where afr added a function called afr_inode_refresh() which does a lookup and populates its inode context in case a FOP came to AFR without a lookup being issued prior to it. We ran a thread on gluster-devel asking for feedback on the need of explicit lookup post readdirp. For responses refer [1]. Refer [2] for discussions happened on gerrit. After gathering inputs from [1] and [2], it looks like there is no xlator in current state that requires an explicit lookup post readdirp to function properly. * A separate similar patch will be sent for gfapi/nfs/nfs-ganesha. Note: Only file's inode is built with readdirp.

Fix: name the process when its spawned and send it to the server and save it in the client_t The processes that abide by this change from this patch are: 1) fuse mount, 2) rebalance, 3) selfheal, 4) tier, 5) quota, 6) snapshot, 7) brick. 8) gfapi (by default. gfapi.<processname> if processname is found) Note: fuse gets a process name as native-fuse-client by default. If the user gives a name for the fuse and spawns it, it will be of this type --process-name native-fuse-client.<name_specified>.

* groups: don't allocate auxiliary gid list on stackCsaba Henk2017-07-061-14/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | When glusterfs wants to retrieve the list of auxiliary gids of a user, it typically allocates a sufficiently big gid_t array on stack and calls getgrouplist(3) with it. However, "sufficiently big" means to be of maximum supported gid list size, which in GlusterFS is GF_MAX_AUX_GROUPS = 64k. That means a 64k * sizeof(gid_t) = 256k allocation, which is big enough to overflow the stack in certain cases. A further observation is that stack allocation of the gid list brings no gain, as in all cases the content of the gid list eventually gets copied over to a heap allocated buffer. So we add a convenience wrapper of getgrouplist to libglusterfs called gf_getgrouplist which calls getgrouplist with a sufficiently big heap allocated buffer (it takes care of the allocation too). We are porting all the getgrouplist invocations to gf_getgrouplist and thus eliminate the huge stack allocation.

* fuse: implement "-oauto_unmount"Csaba Henk2017-05-233-4/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libfuse has an auto_unmount option which, if enabled, ensures that the file system is unmounted at FUSE server termination by running a separate monitor process that performs the unmount when that occurs. (This feature would probably better be called "robust auto-unmount", as FUSE servers usually do try to unmount their file systems upon termination, it's just this mechanism is not crash resilient.) This change implements that option and behavior for glusterfs. Note that "auto unmount" (robust or not) is a leaky abstraction, as the kernel cannot guarantee that at the path where the FUSE fs is mounted is actually the toplevel mount at the time of the umount(2) call, for multiple reasons, among others, see: fuse-devel: "fuse: feasible to distinguish between umount and abort?" http://fuse.996288.n3.nabble.com/fuse-feasible-to-distinguish-between-umount-and-abort-tt14358.html https://github.com/libfuse/libfuse/issues/122 Updates #153 Change-Id: Ia4432580c9fd2c156d9c73c3a44f4bfd42437599 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: https://review.gluster.org/17230 Tested-by: Amar Tumballi <amarts@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Amar Tumballi <amarts@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>

* Halo Replication feature for AFR translatorKevin Vigor2017-05-021-0/+24

Clients can also write synchronously to the cluster simply by specifying a halo-latency which is very large (e.g. 10seconds) which will include all bricks. In other words, it allows clients to decide at mount time if they desire synchronous or asynchronous IO into a cluster and the cluster can support both of these modes to any number of clients simultaneously. There are a few new volume options due to this feature: halo-shd-latency: The threshold below which self-heal daemons will consider children (bricks) connected. halo-nfsd-latency: The threshold below which NFS daemons will consider children (bricks) connected. halo-latency: The threshold below which all other clients will consider children (bricks) connected. halo-min-replicas: The minimum number of replicas which are to be enforced regardless of latency specified in the above 3 options. If the number of children falls below this threshold the next best (chosen by latency) shall be swapped in. New FUSE mount options: halo-latency & halo-min-replicas: As descripted above. This feature combined with multi-threaded SHD support (D1271745) results in some pretty cool geo-replication possibilities. Operational Notes: - Global consistency is gaurenteed for synchronous clients, this is provided by the existing entry-locking mechanism. - Asynchronous clients on the other hand and merely consistent to their region. Writes & deletes will be protected via entry-locks as usual preventing concurrent writes into files which are undergoing replication. Read operations on the other hand should never block. - Writes are allowed from _any_ region and propagated from the origin to all other regions. The take away from this is care should be taken to ensure multiple writers do not write the same files resulting in a gfid split-brain which will require resolution via split-brain policies (majority, mtime & size). Recommended method for preventing this is using the nfs-auth feature to define which region for each share has RW permissions, tiers not in the origin region should have RO perms. TODO: - Synchronous clients (including the SHD) should choose clients from their own region as preferred sources for reads. Most of the plumbing is in place for this via the child_latency array. - Better GFID split brain handling & better dent type split brain handling (i.e. create a trash can and move the offending files into it). - Tagging in addition to latency as a means of defining which children you wish to synchronously write to Test Plan: - The usual suspects, clang, gcc w/ address sanitizer & valgrind - Prove tests Reviewers: jackl, dph, cjh, meyering Reviewed By: meyering Subscribers: ethanr Differential Revision: https://phabricator.fb.com/D1272053 Tasks: 4117827 Change-Id: I694a9ab429722da538da171ec528406e77b5e6d1 BUG: 1428061 Signed-off-by: Kevin Vigor <kvigor@fb.com> Reviewed-on: http://review.gluster.org/16099 Reviewed-on: https://review.gluster.org/16177 Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

* fuse: clean up mount flag processingCsaba Henk2017-04-271-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In general, when one invokes a mount helper program -- basically anything that mounts something based on its command line, so thinking of mount(8), mount.<fs-type> or fusermount, but also of FUSE servers in general, including glusterfs -- the command line arguments that are to affect mount(2) are mapped to a bitmask called the mount flags, which is passed to mount(2), so that the kernel can interpret the flag bits and adjusts properties of the mount accordingly. There is a traditional syntax for this mechanism as implemented in mount(8): one passes "-ocomma,separated,mount,options" and the individual option name strings are mapped to flag bits in mount(8). FUSE further explores this idea and typically the FUSE server command lines allow further option names to be used in the "-ooption,name,list" which are then separated from the kernel sanctioned option names (to which we'll refer as "system mount options") and are passed to a platform specific lower level fuse mount helper interface. The separation of system mount option names and FUSE specific option names is also platform specific, so the general mount interface function, which in case of glusterfs is gf_fuse_mount(), should abstract this away. Therefore we change the signature of this function from int gf_fuse_mount (const char *mountpoint, char *fsname, unsigned long mountflags, char *mnt_param, pid_t *mtab_pid, int status_fd); to int gf_fuse_mount (const char *mountpoint, char *fsname, char *mnt_param, pid_t *mtab_pid, int status_fd); and deal with flag extraction in platform specific mount code. Note that the sole purpose of the mountflags argument was to indicate read-only mounting. The other system mount option names were expected to reside in the comma-separated mnt_param string, but they were not properly processed (see the referred BUG). With the new gf_fuse_mount signature read-only mounting is to be indicated as a "ro" component in mnt_param. - For Darwin, which has a dedicated, separate gf_fuse_mount implementation, gf_fuse_mount was ignoring mountflags, so only the signature had to to be adjusted. However, as bonus, we gain read-only support for Darwin, which was missing so far, given that it was indicated via the ignored mountflags. Darwin's low level mount helper relies on the "ro" component of the option string, which agrees with the new calling convention of gf_fuse_mount. - On Linux, system mount option name handling (apart from the distinguished read-only option) used to have the inadvertent side effect of adding "nosuid,nodev" as indicated in BUG; since Ia89d975d1e27fcfa5ab2036ba546aa8fa0d2d1b0 this side effect is removed, but system mount option name handling was left broken (passing system mount options other than "ro" fails to mount). - On other platforms, system mount option name handling is broken (expect for the distinguished read-only option). As of this change, in the general (non-Darwin) implementation of gf_fuse_mount we take care of proper separation of system mount names and their conversion to mount flags. For Linux, we adopt the conversion table from FUSE upstream. For other systems we just provide a best effort to support those system mount options which are understood across all Unices (nosuid,nodev,noatime,noexec,ro). (This can be improved later to provide proper plaform support.)

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-0/+10
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration, 1. glusterd needs to listen on default port (240007) as IPv6 TCP listner. 2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe needs to work using ipv6 addresses. 3. Bricks needs to listen on ipv6 addresses. All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken.

* fuse: add support for SEEK_HOLE and SEEK_DATA through lseek()Niels de Vos2016-02-102-1/+67
| | | | | | | | | | | | | | | | | | | | The Linux FUSE kernel module has gained support for passing SEEK_HOLE and SEEK_DATA on through lseek(). This can greatly improve performance when working with sparse files. Linux FUSE introduced support for lseek() with version 4.5. The commit in mainline Linux is 0b5da8db145bfd44266ac964a2636a0cf8d7c286.

* Fuse: Add a check for NULL in fuse_itable_dumpAshish Pandey2016-02-081-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Immediately after starting a disperse volume (2+1) kill one brick and just after that try to mount it through fuse. This lead to crash. Our test scripts use process statedumps to determine various things like whether they are up, connected to bricks etc. It takes some time for an active_subvol to be be associated with fuse even after mount process is daemonized. This time is normally a function of completion of handshake with bricks. So, if we try to take statedump in this time window, fuse wouldn't have an active_subvol associated with it leading to this crash. This happened while executing ec-notify.t, which contains above steps. Solution: Check priv and priv->active_subvol for NULL before inode_table_dump. If priv->active_subvol is null its perfectly fine to skip dumping of inode table as inode table is associated with an active_subvol. A Null active_subvol indicates initialization in progress and fuse wouldn't even have started reading requests from /dev/fuse and hence there wouldn't be any inodes or file system activity.

* fuse: update fuse_kernel.h to version 23Ravishankar N2016-02-061-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes were made upstream: - add FUSE_WRITEBACK_CACHE - add time_gran to fuse_init_out - add reserved space to fuse_init_out - add FATTR_CTIME - add ctime and ctimensec to fuse_setattr_in - add FUSE_RENAME2 request - add FUSE_NO_OPEN_SUPPORT flag Including these changes will make it easier to backport support for lseek(). Because the fuse_init_out structure changed its size, older versions of FUSE would fail initializing. When an older version of FUSE is detected, the fuse_init_out structure is reduced to the previous size. This is harmless, as the attributes that are not passed, are not used for earlier versions anyway.

However the kernel does not increment the counter for '.' and '..' entries. This caused kernel to send forgets with a counter smaller than the inode's current value. This prevented these inodes to be retired when ref count was 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prompted by the email exchange in gluster-devel between Oleksandr Natalenko, xavi, and soumyak, I looked at this because the fuse client on the longevity cluster has also been suffering from a serious memory leak for some time. (longevity cluster is currently running 3.7.6) The longevity cluster manifests the same kernel notifier loop terminated log message the Oleksandr sees, and some sample runs suggest that the length passed to the (sys_)write call is unexpectedly and abnormally large. Basically this fix a) uses correct types for len and rv, b) copies the len from potentially incorrectly aligned memory (in a way that should minimize potential performance issues related to accessing unaligned memory.) c) changes log level of the kernel notifier loop terminated message d) fixes a potential mutex lock/unlock issue Change-Id: Icedb3525706f59803878bb37ef6b4ffe4a986880 BUG: 1288857 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/13274 Smoke: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

With this change, all mount options from 'man 8 mount' are explicitly included in the /sbin/mount.glusterfs script. Some of the options are marked with TODO, these are not commonly used and may require some additional support in Gluster/FUSE too.

* performance/write-behind: retry "failed syncs to backend"Raghavendra G2015-12-221-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. When sync fails, the cached-write is still preserved unless there is a flush/fsync waiting on it. 2. When a sync fails and there is a flush/fsync waiting on the cached-write, the cache is thrown away and no further retries will be made. In other words flush/fsync act as barriers for all the previous writes. The behaviour of fsync acting as a barrier is controlled by an option (see below for details). All previous writes are either successfully synced to backend or forgotten in case of an error. Without such barrier fop (especially flush which is issued prior to a close), we end up retrying for ever even after fd is closed. 3. If a fop is waiting on cached-write and syncing to backend fails, the waiting fop is failed. 4. sync failures when no fop is waiting are ignored and are not propagated to application. For eg., a. first attempt of sync of a cached-write w1 fails b. second attempt of sync of w1 succeeds If there are no fops dependent on w1 are issued b/w a and b, application won't know about failure encountered in a. 5. The effect of repeated sync failures is that, there will be no cache for future writes and they cannot be written behind. fsync as a barrier and resync of cached writes post fsync failure: ================================================================== Whether to keep retrying failed syncs post fsync is controlled by an option "resync-failed-syncs-after-fsync". By default, this option is set to "off". If sync of "cached-writes issued before fsync" (to backend) fails, this option configures whether to retry syncing them after fsync or forget them. If set to on, cached-writes are retried till a "flush" fop (or a successful sync) on sync failures. fsync itself is failed irrespective of the value of this option, when there is a sync failure of any cached-writes issued before fsync.
