* glusterfs: discard (hole punch) supportBrian Foster2013-06-131-0/+1
| | | | | | | | | | | | | | | | Add support for the DISCARD file operation. Discard punches a hole in a file in the provided range. Block de-allocation is implemented via fallocate() (as requested via fuse and passed on to the brick fs) but a separate fop is created within gluster to emphasize the fact that discard changes file data (the discarded region is replaced with zeroes) and must invalidate caches where appropriate.

* gluster: add fallocate fop supportBrian Foster2013-06-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement support for the fallocate file operation. fallocate allocates blocks for a particular inode such that future writes to the associated region of the file are guaranteed not to fail with ENOSPC. This patch adds fallocate support to the following areas: - libglusterfs - mount/fuse - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi BUG: 949242 Change-Id: Ice8e61351f9d6115c5df68768bc844abbf0ce8bd Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-on: http://review.gluster.org/4969 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
* dht,posix: support for case discoveryAnand Avati2013-05-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is support for discovering a filename in a given directory which has a case insensitive match of a given name. It is implemented as a virtual extended attribute on the directory where the required filename is specified in the key. E.g: sh# getfattr -e "text" -n user.glusterfs.get_real_filename:FiLe-B /mnt/samba/patchy getfattr: Removing leading '/' from absolute path names # file: mnt/samba/patchy user.glusterfs.get_real_filename:FiLe-B="file-b" In reality, there can be multiple "answers" as the backend filesystem is case sensitive and there can be multiple files which can strcasecamp() successfully. In this case we pick the first matched file from the first responding server. If a matching file does not exist, we return ENOENT (and NOT ENODATA). This way the caller can differentiate between "unsupported" glusterfs API and file not existing. This API is used by Samba VFS to perform efficient discovery of the real filename without doing a full scan at the Samba level.

* features/locks: implement fgetxattr and fsetxattrRaghavendra G2012-11-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | implement xattrs for GF_XATTR_LOCKINFO_KEY, which will be used for posix-locks migration from old to new graph after a switch. fgetxattr (fd, GF_XATTR_LOCKINFO_KEY) will return a dict. This dict has a serialized dict stored for key GF_XATTR_LOCKINFO_KEY. This serialized dict in turn has fdnum value of locks acquired on this fd with modified pathinfo (containing hostname and base directory components) as key. fsetxattr (newfd, GF_XATTR_LOCKINFO_KEY, dict) has following semantics. dict can be the result of a previous fgetxattr with GF_XATTR_LOCKINFO_KEY. In that case, a dict_get on dict constructed using serialized buffer is done on modified pathinfo as key. If a value is got, that value is treated as fdnum and for every lock l on newfd->inode we do, if (l->fdnum == fdnum) { l->fdnum = fd_fdnum (newfd); l->transport = <connection identifier of connection on which fsetxattr came>; } Signed-off-by: Raghavendra G <raghavendra@gluster.com> Change-Id: I73a8f43aa0b6077bc19f8de52205ba748f2d8bbe BUG: 808400 Reviewed-on: http://review.gluster.org/4120 Reviewed-by: Vijay Bellur <vbellur@redhat.com> Tested-by: Vijay Bellur <vbellur@redhat.com>

Tests: From Afr code made an OR_ARRAY with ALL bits set and it reflected on the changelog xattrs. changelog incrementing did not have any effects on the all-set changelog. From Afr code made an AND_ARRAY with 0 and it reflected in the changelog xattrs.

* glusterfs_ctx_t: un-globalize the filesystem contextAnand Avati2012-07-171-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | So far there has been a global glusterfs_ctx_t object which represents the running instance of the filesystem (client or server). It contains the various graphs, connection to the management daemon over which new graphs are obtained, calls stacks issued on this filesystem, and a bunch of such things. With the introduction of libgfapi, it is no more true that there will be only one filesystem context in a process. Applications can be written to use libgfapi and obtain serveral instances of different filesystems/volumes in the same process. This involves messy untangling of assumptions inside libglusterfs that there would only be one global glusterfs_ctx_t and offload that assumption to glusterfsd/ and cli/ (where it is true).

| | | | | | | | | | | | | | | | | | | | | | | | | | This change genericizes the cache mechanism implemented in commit 8efd2845 into libglusterfs/src/gidcache.[ch] and adds fuse-bridge as a client. The cache mechanism is fundamentally equivalent, with some minor changes: - Change cache key from uid_t to uint64_t. - Modify the cache add logic to locate and use an entry with a matching ID, should it already exist. This addresses a bug in the existing mechanism where an expired entry supercedes a newly added entry in lookup, causing repeated adds and flushing of a cache bucket. The fuse group cache is disabled by default. It can be enabled via the 'gid-timeout' fuse-bridge translator option and accompanying mount option (i.e., '-o gid-timeout=1' for a 1s entry timeout).

This patch fixes these issues by a refactor that merges the approaches sported by commits 7d0397c2 fuse: allow requests during mount (needed for SELinux labels) c5d781e0 upon daemonizing, wait on mtab update to terminate in parent Original daemonized libfuse event flow is as follows: try: fd = open("/dev/fuse") mount("-oopts,fd=%s" % fd ...) mount(8) -f # manipulate mtab except: sp = socketpair() env _FUSE_COMMFD=sp fusermount -oopts fd = receive_fd(sp) where fusermount(1) does: fd = open("/dev/fuse") mount("-oopts,fd=%d" % fd ...) sp = atoi(getenv("_FUSE_COMMFD")) send_fd(sp, fd) daemonize( # in child fuse_loop(fd) ) # in parent exit() As of 013850c9 (instead of adopting FUSE's 47e61004¹), we went for async mtab manipulation, and as of c5d781e0, still wanted keep that in sync with termination of daemon parent, so we changed it to: try: fd = open("/dev/fuse") mount("-oopts,fd=%s" % fd ...) pid = fork( # in child mount(8) -f ) except: sp = socketpair() env _FUSE_COMMFD=sp fusermount -oopts fd = receive_fd(sp) daemonize( fuse_loop(fd) ) waitpid(pid) exit() (Note the new approch came only to direct [privileged] mount, so fusermount based mounting was already partially broken.) As of 7d0397c2, with the purpose of facilitating async mount, the event flow was practically reduced to: fd = open("/dev/fuse") fork( mount("-oopts,fd=%s" % fd ...) fork( mount(8) -n ) ) daemonize( fuse_loop(fd) ) exit() Thus fusermount based mounting become defunct; however, the dead code was still kept around. So, we should either drop it or fix it. Also, the mtab manipulator is forked into yet another child with no purpose, while syncing with it in daemon parent is broken. mount(2) is neither synced with parent. Now we are coming to the following scheme: fd = open("/dev/fuse") pid = fork( try: mount("-oopts,fd=%s" % fd ...) mount(8) -n except: env _FUSE_DEVFD=fd fusermount -oopts ) where fusermount(1) does: fd = getenv("_FUSE_DEVFD") mount("-oopts,fd=%s" % fd ...) daemonize( fuse_loop(fd) ) waitpid(pid) exit() Nb.: - We can't help losing compatibility with upstream fusermount, as it sends back the fd only when mount(2) is completed, thus defeating the async mount approach. The 'getenv("_FUSE_DEVFD")' mechanism is specfic to glusterfs' fusermount (at the moment -- sure we can talk about it with upstream) - fusermount opens /dev/fuse at same privilege level as of original process², so we can bravely go on with doing the open unconditionally in original process - Original mounting code actually tries to mount through fusermount _twice_: if first attempt fails, then, assuming subtype support is missing in kernel, it tries again subtype stripped. However, this is redundant, as fusermount internally also performs the subtype check³. Therefore we simplified the logic to have just a single fusermount call. - we revert the changes to mount.glusterfs as of 7d0397c2, as now there is no issue with glusterfs to work around in that scope ¹ http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blobdiff;f=ChangeLog;h=47e61004;hb=4c3d9b19;hpb=e61b775a ² http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blob;f=util/fusermount.c;h=b2e87d95#l1023 ³ http://fuse.git.sourceforge.net/git/gitweb.cgi?p=fuse/fuse;a=blob;f=util/fusermount.c;h=b2e87d95#l839 Change-Id: I0c4ab70e0c5ad7b27337228749b266bcd0ba941d BUG: 811217 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.com/3341 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Anand Avati <avati@redhat.com>

Earlier, the setting of "volume-id" used to happen during the first run of the brick process, leaving of window for bricks part of one volume to be (ab)used by another volume inadvertently. - removed creation of brick directory (if missing), during start volume force. This is to avoid directory creation as part 'force'ful starting of volume and leave the responsibility with the user, who understands the 'availability' of the export directory (brick) better.

This enables separation of xattrs used as gluster-internal commands (handled by pump) for replace-brick, which are not set in the back-end, from xattrs set on the replace-brick source and destinations bricks. * macros definitions from pump.h and glusterd.h, #defining these xattrs have been merged and put into libglusterfs/src/glusterfs.h Change-Id: I87b8bfbf045aa140f5d3f0c9baa9b2e79f87b67b BUG: 783049 Signed-off-by: Rajesh Amaravathi <rajesh@redhat.com> Reviewed-on: http://review.gluster.com/2663 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amar@gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
* Second round of warning suppression.Jeff Darcy2011-09-291-0/+7
| | | | | | | | | | | | | | | | | | | | | | Used a #pragma to kill ~170 in rpcgen code. Added GF_UNUSED to deal with a few more from macros elsewhere. The remainder are function return values (mostly context and dict calls) that really should be checked. Those would be harder to fix without real understanding of the code where they occur, so they remain as reminders. (Patchset 2: deal with older gcc that doesn't handle #pragma GCC diagnostic) (Patchset 3: fix include paths in generated files) (Patchset 4: keep up with trunk, squash 9 new warnings) (Patchset 5: six more, all in AFR) Change-Id: I29760c8c81be4d7e6489312c5d0e92cc24814b7b BUG: 2550 Reviewed-on: http://review.gluster.com/378 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
* cli : new volume statedump commandKaushal M2011-09-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes: 1. Add a new 'volume statedump' command, that performs statedumps of all the bricks in the volume and saves them in a specified location. 2. Add new server option 'server.statedump-path'. 3. Remove multiple function definitions in glusterd.h Statedump Information: The 'volume statedump' command performs statedumps on all the bricks in a given volume. The syntax of the command is, gluster volume statedump <VOLNAME> [type]...... Types include, * all * mem * iobuf * callpool * priv * fd * inode Defaults to 'all' when no type is specified. The statedump files are created by default in /tmp directory of the server on which the bricks are present. This path can be changed by setting the 'server.statedump-path' option. The statedump files will be named as, <brick-name>.<pid of brick process>.dump Change-Id: I01c0e1a8aad490da818e086d89f292bd2ed06fd4 BUG: 1964 Reviewed-on: http://review.gluster.com/321 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amar@gluster.com>
