* afr: support split-brain CLI for replica 3Ravishankar N2019-11-133-2/+115
| | | | | | | | | | | | | | | | | | | | | | | | | Ever since we added quorum checks for lookups in afr via commit bd44d59741bb8c0f5d7a62c5b1094179dd0ce8a4, the split-brain resolution commands would not work for replica 3 because there would be no readables for the lookup fop. The argument was that split-brains do not occur in replica 3 but we do see (data/metadata) split-brain cases once in a while which indicate that there are a few bugs/corner cases yet to be discovered and fixed. Fortunately, commit 8016d51a3bbd410b0b927ed66be50a09574b7982 added GF_CLIENT_PID_GLFS_HEALD as the pid for all fops made by glfsheal. If we leverage this and allow lookups in afr when pid is GF_CLIENT_PID_GLFS_HEALD, split-brain resolution commands will work for replica 3 volumes too. Likewise, the check is added in shard_lookup as well to permit resolving split-brains by specifying "/.shard/shard-file.xx" as the file name (which previously used to fail with EPERM).

* dht: Rebalance causing IO Error - File descriptor in bad stateMohit Agrawal2019-11-135-17/+116
| | | | | | | | | | | | | | | | | | | | | Problem : When a file is migrated, dht attempts to re-open all open fds on the new cached subvol. Earlier, if dht had not opened the fd, the client xlator would be unable to find the remote fd and would fall back to using an anon fd for the fop. That behavior changed with https://review.gluster.org/#/c/glusterfs/+/15804, causing fops to fail with EBADFD if the fd was not available on the cached subvol. The client xlator returns EBADFD if the remote fd is not found but dht only checks for EBADF before re-opening fds on the new cached subvol. Solution: Handle EBADFD at dht code path to avoid the issue > Change-Id: I43c51995cdd48d05b12e4b2889c8dbe2bb2a72d8 > Fixes: bz#1758579 > (cherry picked from commit 9314a9fbf487614c736cf6c4c1b93078d37bb9df) > (Reviewed on upstream link https://review.gluster.org/23518) Change-Id: I43c51995cdd48d05b12e4b2889c8dbe2bb2a72d8 Fixes: bz#1761910

* geo-rep: Fix config upgrade on non-participating nodeKotresh HR2019-11-063-1/+181
| | | | | | | | | | | | | | | | | | | After upgrade, if the config files are of old format, it gets migrated to new format. Monitor process migrates it. Since monitor doesn't run on nodes where bricks are not hosted, it doesn't get migrated there. So this patch fixes the config upgrade on nodes which doesn't host bricks. This happens during config either on get/set/reset.

* geo-rep: Fix the name of changelog archive fileKotresh HR2019-11-062-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Background: The processed changelogs are archived each month in a single tar file. The default format is "archive_YYYYMM.tar" which is specified as "%%Y%%m" in configuration file. Problem: The created changelog archive file didn't have corresponding year and month. It created as "archive_%Y%m.tar" on python2 only systems. Cause and Fix: Geo-rep expects "%Y%m" after the ConfigParser reads it from config file. Since it was "%%Y%%m" in config file, geo-rep used to get correct value "%Y%m" in python3 and "%%Y%%m" in python2 which is incorrect. The fix can be to use "%Y%m" in config file but that fails in python3. So the fix is to use "RawConfigParser" in geo-rep and use "%Y%m". This works both in python2 and python3.

* geo-rep : fix gluster command path for non-root sessionSunny Kumar2019-11-062-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: gluster command not found. Cause: In Volinfo class we issue command 'gluster vol info' to get information about volume like getting brick_root to perform various operation. When geo-rep session is configured for non-root user Volinfo class fails to issue gluster command due to unavailability of gluster binary path for non-root user. Solution: Use config value 'slave-gluster-command-dir'/'gluster-command-dir' to get path for gluster command based on caller.

* core: fix memory allocation issuesv7.0rc1Xavi Hernandez2019-09-162-27/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | Two problems have been identified that caused that gluster's memory usage were twice higher than required. 1. An off by 1 error caused that all objects allocated from the memory pools were taken from a pool bigger than required. Since each pool corresponds to a size equal to a power of two, this was wasting half of the available memory. 2. The header information used for accounting on each memory object was not taken into consideration when searching for a suitable memory pool. It was added later when each individual block was allocated. This made this space "invisible" to memory accounting. Credits: Thanks to Nithya Balachandran for identifying this problem and testing this patch. >Fixes: bz#1722802 Change-Id: I90e27ad795fe51ca11c13080f62207451f6c138c >Signed-off-by: Xavi Hernandez <xhernandez@redhat.com> >(cherry picked from commit 1716a907da1a835b658740f1325033d7ddd44952) Fixes: bz#1748774 Change-Id: I90e27ad795fe51ca11c13080f62207451f6c138c Signed-off-by: Xavi Hernandez <xhernandez@redhat.com>

* [RFC] change get_real_filename implementation to use ENOATTR instead of ENOENTMichael Adam2019-09-032-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | get_real_filename is implemented as a virtual extended attribute to help Samba implement the case-insensitive but case preserving SMB protocol more efficiently. It is implemented as a getxattr call on the parent directory with the virtual key of "get_real_filename:<entryname>" by looking for a spelling with different case for the provided file/dir name (<entryname>) and returning this correct spelling as a result if the entry is found. Originally (05aaec645a6262d431486eb5ac7cd702646cfcfb), the implementation used the ENOENT errno to return the authoritative answer that <entryname> does not exist in any case folding. Now this implementation is actually a violation or misuse of the defined API for the getxattr call which returns ENOENT for the case that the dir that the call is made against does not exist and ENOATTR (or the synonym ENODATA) for the case that the xattr does not exist. This was not a problem until the gluster fuse-bridge was changed to do map ENOENT to ESTALE in 59629f1da9dca670d5dcc6425f7f89b3e96b46bf, after which we the getxattr call for get_real_filename returned an ESTALE instead of ENOENT breaking the expectation in Samba. It is an independent problem that ESTALE should not leak out to user space but is intended to trigger retries between fuse and gluster. But nevertheless, the semantics seem to be incorrect here and should be changed. This patch changes the implementation of the get_real_filename virtual xattr to correctly return ENOATTR instead of ENOENT if the file/directory being looked up is not found. The Samba glusterfs_fuse vfs module which takes advantage of the get_real_filename over a fuse mount will receive a corresponding change to map ENOATTR to ENOENT. Without this change, it will still work correctly, but the performance optimization for nonexisting files is lost. On the other hand side, this change removes the distinction between the old not-implemented case and the implemented case. So Samba changed to treat ENOATTR like ENOENT will not work correctly any more against old servers that don't implement get_real_filename. I.e. existing files will be reported as non-existing Change-Id: I971b427ab8410636d5d201157d9af70e0d075b67 fixes: bz#1745914 Signed-off-by: Michael Adam <obnox@samba.org> (cherry picked from commit dc1b87fcfef08c9497b0c02b2410c9d18bbc2dba)

So open fop will create just the gfid which will lead to problems. Fix: Filter out these two flags in reopen.

* cluster/ec: fix EIO error for concurrent writes on sparse filesXavi Hernandez2019-08-222-10/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EC doesn't allow concurrent writes on overlapping areas, they are serialized. However non-overlapping writes are serviced in parallel. When a write is not aligned, EC first needs to read the entire chunk from disk, apply the modified fragment and write it again. The problem appears on sparse files because a write to an offset implicitly creates data on offsets below it (so, in some way, they are overlapping). For example, if a file is empty and we read 10 bytes from offset 10, read() will return 0 bytes. Now, if we write one byte at offset 1M and retry the same read, the system call will return 10 bytes (all containing 0's). So if we have two writes, the first one at offset 10 and the second one at offset 1M, EC will send both in parallel because they do not overlap. However, the first one will try to read missing data from the first chunk (i.e. offsets 0 to 9) to recombine the entire chunk and do the final write. This read will happen in parallel with the write to 1M. What could happen is that half of the bricks process the write before the read, and the half do the read before the write. Some bricks will return 10 bytes of data while the otherw will return 0 bytes (because the file on the brick has not been expanded yet). When EC tries to recombine the answers from the bricks, it can't, because it needs more than half consistent answers to recover the data. So this read fails with EIO error. This error is propagated to the parent write, which is aborted and EIO is returned to the application. The issue happened because EC assumed that a write to a given offset implies that offsets below it exist. This fix prevents the read of the chunk from bricks if the current size of the file is smaller than the read chunk offset. This size is correctly tracked, so this fixes the issue. Also modifying ec-stripe.t file for Test #13 within it. In this patch, if a file size is less than the offset we are writing, we fill zeros in head and tail and do not consider it strip cache miss. That actually make sense as we know what data that part holds and there is no need of reading it from bricks.

* event: rename event_XXX with gf_ prefixedXiubo Li2019-08-2115-90/+92
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I hit one crash issue when using the libgfapi. In the libgfapi it will call glfs_poller() --> event_dispatch() in file api/src/glfs.c:721, and the event_dispatch() is defined by libgluster locally, the problem is the name of event_dispatch() is the extremly the same with the one from libevent package form the OS. For example, if a executable program Foo, which will also use and link the libevent and the libgfapi at the same time, I can hit the crash, like: kernel: glfs_glfspoll[68486]: segfault at 1c0 ip 00007fef006fd2b8 sp 00007feeeaffce30 error 4 in libevent-2.0.so.5.1.9[7fef006ed000+46000] The link for Foo is: lib_foo_LADD = -levent $(GFAPI_LIBS) It will crash. This is because the glfs_poller() is calling the event_dispatch() from the libevent, not the libglsuter. The gfapi link info : GFAPI_LIBS = -lacl -lgfapi -lglusterfs -lgfrpc -lgfxdr -luuid If I link Foo like: lib_foo_LADD = $(GFAPI_LIBS) -levent It will works well without any problem. And if Foo call one private lib, such as handler_glfs.so, and the handler_glfs.so will link the GFAPI_LIBS directly, while the Foo won't and it will dlopen(handler_glfs.so), then the crash will be hit everytime. The link info will be: foo_LADD = -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) I can avoid the crash temporarily by linking the GFAPI_LIBS in Foo too like: foo_LADD = $(GFAPI_LIBS) -levent libhandler_glfs_LIBADD = $(GFAPI_LIBS) But this is ugly since the Foo won't use any APIs from the GFAPI_LIBS. And in some cases when the --as-needed link option is added(on many dists it is added as default), then the crash is back again, the above workaround won't work.

* posix/ctime: Fix race during lookup ctime xattr healKotresh HR2019-08-191-18/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Ctime heals the ctime xattr ("trusted.glusterfs.mdata") in lookup if it's not present. In a multi client scenario, there is a race which results in updating the ctime xattr to older value. e.g. Let c1 and c2 be two clients and file1 be the file which doesn't have the ctime xattr. Let the ctime of file1 be t1. (from backend, ctime heals time attributes from backend when not present). Now following operations are done on mount c1 -> ls -l /mnt/file1 | c2 -> ls -l /mnt/file1;echo "append" >> /mnt/file1; The race is that the both c1 and c2 didn't fetch the ctime xattr in lookup, so both of them tries to heal ctime to time 't1'. If c2 wins the race and appends the file before c1 heals it, it sets the time to 't1' and updates it to 't2' (because of append). Now c1 proceeds to heal and sets it to 't1' which is incorrect. Solution: Compare the times during heal and only update the larger time. This is the general approach used in ctime feature but got missed with healing legacy files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The files which were created before ctime enabled would not have "trusted.glusterfs.mdata"(stores time attributes) xattr.

It should update only the corresponding time attribute and rest from backend Solution: Creating xattr with values from brick is not possible as each brick of replica set would have different times. So create the xattr upon successful lookup if the xattr is not created Note To Reviewers: The time attributes used to set xattr is got from successful lookup. Instead of sending the whole iatt over the wire via setxattr, a structure called mdata_iatt is sent. The mdata_iatt contains only time attributes.
