* afr: stop encoding subvolume id in readdir d_offAnand Avati2014-12-263-131/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of encoding d_off in AFR is to indicate the selected subvolume for the first readdir, and continue all further readdirs of the session on the same subvolume. This is required because, unlike files, dir d_offs are specific to the backend and cannot be re-used on another subvolume. The d_off transformation encodes the subvolume id and prevents such invalid use of d_offs on other servers. However, this approach could be quite wasteful of precious d_off bit-space. Unlike DHT, where server id can change from entry to entry and thus encoding the server id in the transformed d_off is necessary, we could take a slightly relaxed approach in AFR. The approach is to save the subvolume where the last readdir request was sent in the fd_ctx. This consumes constant space (i.e no per-entry cache), and serves the purpose of avoiding d_off "misuse" (i.e using d_off from one server on another). The compromise here is NFS resuming readdir from a non-0 cookie after an extended delay (either anonymous FD has been reclaimed, or server has restarted). In such cases a subvolume is picked freshly. To make this fresh picking more deterministic (i.e, to pick the same subvolume whenever possible, even after reboots), the function afr_hash_child (used by afr_read_subvol_select_by_policy) is modified to skip all dynamic inputs (i.e PID) for the case of directories.

* Avoid spurious directory metedata split brainEmmanuel Dreyfus2014-12-221-1/+115
| | | | | | | | | | | | | | | | | | | When directory content is modified, [mc]time is updated. On Linux, the filesystem does it, while at least on NetBSD, the kernel file-system independant code does it. This means that when entries are added while bricks are down, the kernel sends a SETATTR [mc]time which will cause metadata split brain for the directory. In this case, clear the split brain by finding the source with the most recent modification date.

* glusterd: Maintain per transaction xaction_peers list in syncop & mgmt_v3Atin Mukherjee2014-12-226-139/+256
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current implementation xaction_peers list is maintained in a global variable (glustrd_priv_t) for syncop/mgmt_v3. This means consistency and atomicity of peerinfo list across transactions is not guranteed when multiple syncop/mgmt_v3 transaction are going through. We had got into a problem in mgmt_v3-locks.t which was failing spuriously, the reason for that was two volume set operations (in two different volume) was going through simultaneouly and both of these transaction were manipulating the same xaction_peers structure which lead to a corrupted list. Because of which in some cases unlock request to peer was never triggered and we end up with having stale locks. Solution is to maintain a per transaction local xaction_peers list for every syncop. Please note I've identified this problem in op-sm area as well and a separate patch will be attempted to fix it. Finally thanks to Krishnan Parthasarathi and Kaushal M for your constant help to get to the root cause.

* gfapi: always close the fd in glfs_h_creat()Niels de Vos2014-12-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | When running stress and performance tests against nfs-ganesha, the number of open file descriptors increases continously. If the tests run long enough, the brick processes will eventually run out of file descriptors. This seems to be caused by glfs_h_creat() which allocates a 'struct glfs_fd', but does not release it. A normal glfs_creat() returns the file descriptor to the application, whereas glfs_h_creat() returns a handle (struct glfs_object). The file descriptor associated with the handle can not be release by glfapi-applications. This fd-leak can be prevented by destroying the 'struct glfs_fd' before returning the 'struct gfls_object' to the gfapi-application.

* telldir()/seekdir() portability fixesEmmanuel Dreyfus2014-12-179-31/+137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | POSIX says that an offset obtained from telldir() can only be used on the same DIR *. Linux is abls to reuse the offset accross closedir()/opendir() for a given directory, but this is not portable and such a behavior should be fixed. An incomplete fix for the posix xlator was merged in http://review.gluster.com/8926 This change set completes it. - Perform the same fix index xlator. - Use appropriate casts and variable types so that 32 bit signed offsets obtained by telldir() do not get clobbered when copied into 64 bit signed types. - modify glfs-heal.c and afr-self-heald.c so that they do not use anonymous fd, since this will cause closedir()/opendir() between each syncop_readdir(). On failure we fallback to anonymous fs only for Linux so that we can cope with updated client vs not updated brick. - Avoid sending an EINVAL when the client request for the EOF offset. Here we fix an error in previous fix for posix xlator: since we fill each directory entry with the offset of the next entry, we must consider as EOF the offset of the last entry, and not the value of telldir() after we read it. - Add checks in regression tests that we do not hit cases where offsets fed to seekdir() are wrong. Introduce log_newer() shell function to check for messages produced by the current script. This fix gather changes from http://review.gluster.org/9047 and http://review.gluster.org/8936 making them obsolete.

* gfapi: new inode created in glfs_resolve_component even if inode is in inode ↵Rajesh Joseph2014-12-081-6/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | table problem: USS allows split-brain file to be accessed while main volume gives I/O error. cause: AFR detects split-brain on lookup. It stores this information in inode context. open and readv fop checks this flag from inode context. open and readv fop fails if split-brain flag is set for the file. USS uses gfapi to access snapshot volume. During open call gfapi internally calls glfs_resolve_component. glfs_resolve_component generates a new inode even if inode is present for the file. Because of which afr_lookup acts on a new inode which does not contain the split-brain flag.

* ec: Fix self-healing issues.Xavier Hernandez2014-12-0410-313/+548

Self healing is executed in background, allowing the fop that detected the problem to continue without blocks nor delays. While this is quite interesting to avoid unnecessary delays, it can cause spurious failures of self-heal because it may try to recover a file inside a directory that a previous self-heal has not recovered yet, causing the file self-heal to fail. 2. When a partial self-heal is being executed on a directory, if a full self-heal is attempted, it won't be executed because another self-heal is already in process, so the directory won't be fully repaired. 3. Information contained in loc's of some fop's is not enough to do a complete self-heal. To solve these problems, I've made some changes: * Improved ec_loc_from_loc() to add all available information to a loc. * Before healing an entry, it's parent is checked and partially healed if necessary to avoid failures. * All heal requests received for the same inode while another self-heal is being processed are queued. When the first heal completes, all pending requests are answered using the results of the first heal (without full execution), unless the first heal was a partial heal. In this case all partial heals are answered, and the first full heal is processed normally. * An special virtual xattr (not physically stored on bricks) named 'trusted.ec.heal' has been created to allow synchronous self-heal of files. Now, the recommended way to heal an entire volume is this: find <mount> -d -exec getfattr -h -n trusted.ec.heal {} \; Some minor changes: * ec_loc_prepare() has been renamed to ec_loc_update(). * All loc management functions return 0 on success and -1 on error. * Do not delay fop unlocks if heal is needed. * Added basic ec xattrs initially on create, mkdir and mknod fops. * Some coding style changes Change-Id: I2a5fd9c57349a153710880d6ac4b1fa0c1475985 BUG: 1161588 Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> Reviewed-on: http://review.gluster.org/9072 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com>

But since the tested file was accessed just before that operations, it may still be in kernel page cache. As a result, file read is handled by kernel cache and never sent to the filesystem, and the test is successful where it should have failed. Fix this by waiting 10s before reading the supposed-to-be-broken file.
