* glusterd: socketfile & pidfile related fixes for brick multiplexing featureMohit Agrawal2017-05-101-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: While brick-muliplexing is on after restarting glusterd, CLI is not showing pid of all brick processes in all volumes. Solution: While brick-mux is on all local brick process communicated through one UNIX socket but as per current code (glusterd_brick_start) it is trying to communicate with separate UNIX socket for each volume which is populated based on brick-name and vol-name.Because of multiplexing design only one UNIX socket is opened so it is throwing poller error and not able to fetch correct status of brick process through cli process. To resolve the problem write a new function glusterd_set_socket_filepath_for_mux that will call by glusterd_brick_start to validate about the existence of socketpath. To avoid the continuous EPOLLERR erros in logs update socket_connect code. Test: To reproduce the issue followed below steps 1) Create two distributed volumes(dist1 and dist2) 2) Set cluster.brick-multiplex is on 3) kill glusterd 4) run command gluster v status After apply the patch it shows correct pid for all volumes > BUG: 1444596 > Change-Id: I5d10af69dea0d0ca19511f43870f34295a54a4d2 > Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> > Reviewed-on: https://review.gluster.org/17101 > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Prashanth Pai <ppai@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> > (cherry picked from commit 21c7f7baccfaf644805e63682e5a7d2a9864a1e6) Change-Id: I1892c80b9ffa93974f20c92d421660bcf93c4cda BUG: 1449002 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: https://review.gluster.org/17210 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: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Prashanth Pai <ppai@redhat.com>
* glusterd: add a cli command to trigger a statedump on a clientPoornima G2017-02-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this, we will be able to trigger statedumps on remote Gluster clients, mainly targetted for applications using libgfapi. Design: SIGUSR signal is the most comman way of taking a statedump in Gluster. But it cannot be used for libgfapi based processes, as the process loading the library might have already consumed SIGUSR signal. Hence going by the command way. One has to issue a Gluster command to initiate a statedump on the libgfapi based client. The command takes hostname and PID as an argument. All the glusterds in the cluster, check if they are connected to the specified hostname, and send an RPC request to all the connected clients from that hostname (via the mgmt connection). > URL: http://review.gluster.org/16357 > BUG: 1169302 > Signed-off-by: Poornima G <pgurusid@redhat.com> > [ndevos: minor fixes and split patch in smaller pieces] > Reviewed-on-master: https://review.gluster.org/9228 > Reviewed-by: Niels de Vos <ndevos@redhat.com> > Tested-by: Niels de Vos <ndevos@redhat.com> > Reviewed-by: Kaleb KEITHLEY <kkeithle@redhat.com> > Reviewed-by: Samikshan Bairagya <samikshan@gmail.com> BUG: 1418981 Change-Id: Icbe4d2f026b32a2c7d5535e1bfb2cdaaff042e91 Signed-off-by: Shyam <srangana@redhat.com> Reviewed-on: https://review.gluster.org/16601 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Niels de Vos <ndevos@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>

* afr: Ignore gluster internal (virtual) xattrs in metadata heal checkRavishankar N2016-09-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In arbiter configuration, posix-xlator in the arbiter brick always sets the GF_CONTENT_KEY in the response dict with a value 0. If the file size on the data bricks is more than quick-read's max-file-size (64kb default), those bricks don't set the key. Because of this difference in the no. of dict elements, afr triggers metadata heal in lookup code path, in turn leading to extra lookups+inodelks. Fix: Changed afr dict comparison logic to ignore all virtual xattrs and the on-disk ones that we should not be healing. Also removed is_virtual_xattr() function. The original callers to this function (upcall) don't seem to need it anymore.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there is no existing CLI that can be used to get the local state representation of the cluster as maintained in glusterd in a readable as well as parseable format. The CLI added has the following usage: # gluster get-state [daemon] [odir <path/to/output/dir>] [file <filename>] This would dump data points that reflect the local state representation of the cluster as maintained in glusterd (no other daemons are supported as of now) to a file inside the specified output directory. The default output directory and filename is /var/run/gluster and glusterd_state_<timestamp> respectively. The option for specifying the daemon name leaves room to add support for other daemons in the future. Following are the data points captured as of now to represent the state from the local glusterd pov: * Peer: - Primary hostname - uuid - state - connection status - List of hostnames * Volumes: - name, id, transport type, status - counts: bricks, snap, subvol, stripe, arbiter, disperse, redundancy - snapd status - quorum status - tiering related information - rebalance status - replace bricks status - snapshots * Bricks: - Path, hostname (for all bricks these info will be shown) - port, rdma port, status, mount options, filesystem type and signed in status for bricks running locally. * Services: - name, online status for initialised services * Others: - Base port, last allocated port - op-version - MYUUID Change-Id: I4a45cc5407ab92d8afdbbd2098ece851f7e3d618 BUG: 1353156 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: http://review.gluster.org/14873 Reviewed-by: Avra Sengupta <asengupt@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
* cluster/afr: Prevent split-brain when bricks are brought off and on in ↵Krutika Dhananjay2016-08-221-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cyclic order When the bricks are brought offline and then online in cyclic order while writes are in progress on a file, thanks to inode refresh in write txns, AFR will mostly fail the write attempt when the only good copy is offline. However, there is still a remote possibility that the file will run into split-brain if the brick that has the lone good copy goes offline *after* the inode refresh but *before* the write txn completes (I call it in-flight split-brain in the patch for ease of reference), requiring intervention from admin to resolve the split-brain before the IO can resume normally on the file. To get around this, the patch does the following things: i) retains the dirty xattrs on the file ii) avoids marking the last of the good copies as bad (or accused) in case it is the one to go down during the course of a write. iii) fails that particular write with the appropriate errno. This way, we still have one good copy left despite the split-brain situation which when it is back online, will be chosen as source to do the heal.

* core: use readdir(3) with glibc, and associated cleanupKaleb S. KEITHLEY2016-07-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting with glibc-2.23 (i.e. what's in Fedora 25), readdir_r(3) is marked as deprecated. Specifically the function decl in <dirent.h> has the deprecated attribute, and now warnings are thrown during the compile on Fedora 25 builds. The readdir(_r)(3) man page (on Fedora 25 at least) and World+Dog say that glibc's readdir(3) is, and always has been, MT-SAFE as long as only one thread is accessing the directory object returned by opendir(). World+Dog also says there is a potential buffer overflow in readdir_r(). World+Dog suggests that it is preferable to simply use readdir(). There's an implication that eventually readdir_r(3) will be removed from glibc. POSIX has, apparently deprecated it in the standard, or even removed it entirely. Over and above that, our source near the various uses of readdir(_r)(3) has a few unsafe uses of strcpy()+strcat(). (AFAIK nobody has looked at the readdir(3) implemenation in *BSD to see if the same is true on those platforms, and we can't be sure of MacOS even though we know it's based on *BSD.)

From NFS client's perspective it thinks the file is changed. Tar which depends on this to be correct keeps giving 'file changed as we read it' warning.

Solution: If we can define different port ranges for clients incase where secure ports exhaust, we can avoid the maximum port clashes with in gluster processes. Still we are prone to have clashes with other non-gluster processes, but the chances being very low in the rhgs Env, but that's a different story on its own, which will be handled in upcoming patches.

* glusterd: Bug fixes for IPv6 supportNithin D2016-02-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Fix: When "option transport.address-family inet6" option is present in glusterd.vol file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved inside brick volume files used by glusterfsd brick process when they are starting. Tests Run: Regression tests using ./run-tests.sh IPv4: Ran manually till tests/basic/rpm.t . IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts) Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here Unit Tests using Ipv6 peer probe add-bricks remove-bricks create volume replace-bricks start volume stop volume delete volume Change-Id: Iebc96e6cce748b5924ce5da17b0114600ec70a6e BUG: 1117886 Signed-off-by: Nithin D <nithind1988@yahoo.in> Reviewed-on: http://review.gluster.org/11988 Smoke: Gluster Build System <jenkins@build.gluster.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>
* performance/write-behind: retry "failed syncs to backend"Raghavendra G2015-12-221-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* storage/posix: Implement .unlink directoryAshish Pandey2015-12-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | Problem: For EC volume, If a file descriptor is open and file has been unlinked, any further write on that fd will fail. When a write request comes, EC internally reads some blocks using anonymous fd. This read will fail as the file has already been unlinked. Solution: To solve this issue, we are using .unlink directory to keep track of unlinked file. If a file is to be unlinked while its fd is open, move this to .unlink directory and unlink it from .glusterfs and real path. Once all the fd will be closed, remove this entry form .unlink directory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: - Using sampling feature you can record details about every Nth FOP. The fields in each sample are: FOP type, hostname, uid, gid, FOP priority, port and time taken (latency) to fufill the request. - Implemented using a ring buffer which is not (m/c) allocated in the IO path, this should make the sampling process pretty cheap. - DNS resolution done @ dump time not @ sample time for performance w/ cache - Metrics can be used for both diagnostics, traffic/IO profiling as well as P95/P99 calculations - To control this feature there are two new volume options: diagnostics.fop-sample-interval - The sampling interval, e.g. 1 means sample every FOP, 100 means sample every 100th FOP diagnostics.fop-sample-buf-size - The size (in bytes) of the ring buffer used to store the samples. In the even more samples are collected in the stats dump interval than can be held in this buffer, the oldest samples shall be discarded. Samples are stored in the log directory under /var/log/glusterfs/samples. - Uses DNS cache written by sshreyas@fb.com (Thank-you!), the DNS cache TTL is controlled by the diagnostics.stats-dnscache-ttl-sec option and defaults to 24hrs. Test Plan: - Valgrind'd to ensure it's leak free - Run prove test(s) - Shadow testing on 100+ brick cluster Change-Id: I9ee14c2fa18486b7efb38e59f70687249d3f96d8 BUG: 1271310 Signed-off-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-on: http://review.gluster.org/12210 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

As a result CTR used to fail to update the db. Solution: Using the same db connection of CTR for reseting the heat counters. 1) Introducted a new IPC FOP for CTR 2) After the query do a ipc syncop to the underlying client xlator associated to the brick. 3) CTR in brick will catch the IPC FOP and cleat the heat counters.

Georep will run in all the nodes of master and processes changelogs "independently". Processing changelogs is in brick level, but all the fops will be replayed on "slave mount" point. Problem: With a DHT volume, in changelog "internal fops" are NOT recorded. For Rename case, Rename is recorded in "hashed" brick changelog. (DHT's internal fops like creating linkto file, unlink is NOT recorded). This lead us to inconsistent rename operations. For example, Distribute volume created with Two bricks B1, B2. //Consider master volume mounted @ /mnt/master and following operations executed: cd /mnt/master touch f1 // f1 falls on B1 Hash mv f1 f2 // f2 falls on B2 Hash // Here, Changelogs are recorded as below: @B1 CREATE f1 @B2 RENAME f1 f2 Here, race exists between Brick B1 and B2, say B2 will get executed first. Source file f1 itself is "NOT PRESENT", so it will go ahead and create f2 (Current implementation). We have this problem When rename falls in another brick and file is unlinked in Master. Similar kind of issue exists in following case too(multiple rename): CREATE f1 RENAME f1 f2 RENAME f2 f1 Solution: Instead of carrying out "changelogging" at "HASHED volume", carry out at the "CACHED volume". This way we have rename operations carried out where actual files are present. So,Changelog recorded as : @B1 CREATE f1 RENAME f1 f2 credit: sarumuga@redhat.com PS: Some of the races as the one below are _NOT_ fixed by this patch * f1 and f2 exist. B1 and B2 are their respective cached subvols. For both files hashed-subvol == cached-subvol * mv f1 f2 on master. * B1 has change-log entry of rename f1 f2 * rebalance migrates f2 from B1 and B2 * mv f2 f1 on master. * B2 has change-log entry of rename f2 f1 Since changelog entries (rename f1 f2) and (rename f2 f1) are processed independently by gsyncds, which of either f1 and f2 survives on slave is subject to race. Note that on master its file f1 with name f1 which survived. On slave it can be either file f1 with name f1 or file f2 with name f2 based on who wins the race of processing changelog.

Demotion: ~~~~~~~~ When a file gets demoted it get the wind/unwind time stamp is set to zero. The following writes or reads during the migration wont heat the file. What is remaining ? ~~~~~~~~~~~~~~~~~ Bug 1209129 ( https://bugzilla.redhat.com/show_bug.cgi?id=1209129 ) Inspite of this fix there is still a issue remaining, i.e the heat of the file is not keep intact during a internal rebalance activity i.e a rebalance within a tier.

* Avoid conflict between contrib/uuid and system uuidEmmanuel Dreyfus2015-04-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* features/bit-rot: filesystem scrubberVenky Shankar2015-03-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Scrubber performs signature verification for objects that were signed by signer. This is done by recalculating the signature (using the hash algorithm the object was signed with) and verifying it aginst the objects persisted signature. Since the object could be undergoing IO opretaion at the time of hash calculation, the signature may not match objects persisted signature. Bitrot stub provides additional information about the stalesness of an objects signature (determinted by it's versioning mechanism). This additional bit of information is used by scrubber to determine the staleness of the signature, and in such cases the object is skipped verification (although signature staleness is performed twice: once before initiation of hash calculation and another after it (an object could be modified after staleness checks). The implmentation is a part of the bitrot xlator (signer) which acts as a signer or scrubber based on a translator option. As of now the scrub process is ever running (but has some form of weak throttling mechanism during filesystem scan). Going forward, there needs to be some form of scrub scheduling and IO throttling (during hash calculation) tunables (via CLI).
