* rpm: add thin-arbiter packagev6.0rc1Ashish Pandey2019-03-138-63/+220
| | | | | | | | | | | | | | | | | | | | Discussion on thin arbiter volume - https://github.com/gluster/glusterfs/issues/352#issuecomment-350981148 Main idea of having this rpm package is to deploy thin-arbiter without glusterd and other commands on a node, and all we need on that tie-breaker node is to run a single glusterfs command. Also note that, no other glusterfs installation needs thin-arbiter.so. Make sure RPM contains sample vol file, which can work by default, and a script to configure that volfile, along with translator image.

* cluster/afr: Send truncate on arbiter brick from SHDkarthik-us2019-03-123-16/+52
| | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume configuration SHD will not send any writes onto the arbiter brick even if there is data pending marker for the arbiter brick. If we have a arbiter setup on the geo-rep master and there are data pending markers for the files on arbiter brick, SHD will not mark any data changelog during healing. While syncing the data from master to slave, if the arbiter-brick is considered as ACTIVE, then there is a chance that slave will miss out some data. If the arbiter brick is being newly added or replaced there is a chance of slave missing all the data during sync. Fix: If there is data pending marker for the arbiter brick, send truncate on the arbiter brick during heal, so that it will record truncate as the data transaction in changelog.

* dict: handle STR_OLD data type in xdr conversionsAmar Tumballi2019-03-082-0/+3
| | | | | | | | | | | | | | | | | Currently a dict conversion on wire for 3.x protocol happens using `dict_unserialize()`, which sets the type of data as STR_OLD. But the new protocol doesn't send it over the wire as its not considered as a valid format in new processes. But considering we deal with old and new protocol when we do a rolling upgrade, it will allow us to get all the information properly with new protocol.

* performance/readdir-ahead: fix deadlockRaghavendra Gowdappa2019-03-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | This deadlock happens while processing dentry corresponding to current directory (.) in rda_fill_readdirp. In this case following order is followed: LOCK(directory_fd_ctx->lock); rda_inode_ctx_get_iatt -> LOCK(directory_inode->lock); However, in rda_mark_inode_dirty following lock order is followed: LOCK(directory_inode->lock); LOCK(directory_fd_ctx->lock); these two codepaths when executed concurrently resulted in a deadlock. Current patch fixes this by removing locking directory inode and fd-ctx in rda_fill_readdirp. This is fine as directory inode's stat won't change due to writes to files within directory.

* io-threads: Prioritize fops with NO_ROOT_SQUASH pidSusant Palai2019-03-061-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | There was 30% regression observed in mkdir path with commit b139bc58eb504adf5ef81658896c9283ae21f390. On analysis it is found that io-threads xlator deprioritzes fops with all -ve pid. Some context in to the no-root-squash pid requirement: DHT xlator does some of the internal fops with root privileges. This is needed so that operations like layout healing should not be abandoned because a non root user is operating. If root-squash option is enabled the layout set operation looses its root privilege as server xlator converts the uid and pid to random numbers. Hence, the above mentioned commit converted pid to GF_CLIENT_PID_NO_ROOT_SQUASH to continue fops as root. Combining the above I am proposing not to deprioritize fops with no-root-squash pid. > Change-Id: I54d056c01b25729304a77f9242fbaff39c5672ba > fixes: bz#1676430 > Signed-off-by: Susant Palai <spalai@redhat.com> (cherry picked from commit f5c3b1727f55ffaa3dcdb3c3a09b968ebb45dbb2) Change-Id: I54d056c01b25729304a77f9242fbaff39c5672ba fixes: bz#1676429 Signed-off-by: Susant Palai <spalai@redhat.com>

* cluster/dht: Request linkto xattrs in dht_rmdir opendirN Balachandran2019-02-221-1/+26
| | | | | | | | | | | | | | | | | | If parallel-readdir is enabled, the rda xlator is loaded below dht in the graph and proactively lists and caches entries when an opendir is performed. dht_rmdir checks if the directory being deleted contains stale linkto files by performing a readdirp on its child subvols. However, as the entries are actually read in during the opendir operation which does not request the linkto xattr,no linkto xattrs are present for the entries causing dht to incorrectly identify them as data files and fail the rmdir operation with ENOTEMPTY. DHT now always adds the linkto xattr in the list of xattrs requested in the opendir.

Otherwise, inode and hence the context wb_inode can be freed by the type we try to unlock wb_inode 2. wb_readdirp_mark_end iterates over a list of wb_inodes of children of a directory. But inodes could've been freed and hence the list might be corrupted. To fix take a reference on inode before adding it to invalidate_list of parent.

* performance/md-cache: introduce an option to control invalidation of inodesRaghavendra Gowdappa2019-02-182-10/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Explicit invalidation by calling inode_invalidate is necessary when same (meta)data is shared/access across multiple mounts. Without an explicit inode_invalidate call, caches in the mount which didn't witness writes wouldn't be aware of changes as writes wouldn't have passed through them. However, if (meta)data is not shared, all relevant I/O goes through the cache of single mount and hence is coherent with (meta)data on bricks always. So, explicit inode invalidation can be disabled for this case which gives a huge performance boost for workloads that write data and then immediately read the data they just wrote. Note that otherwise, local writes (which pass through the cache) will change ctime and cause unnecessary invalidations. The name of the option that controls this behavior is "performance.global-cache-invalidation". This option is global and it purges caches both in glusterfs and kernel stack for native FUSE mounts. For non-native FUSE mounts, it purges cache only from glusterfs stack. This option is effective only when performance.stat-prefetch is on. Note that there is a similar option "performance.cache-invalidation", but the scope of that option is limited to quick-read and md-cache.

* glusterd: get-state command should not fail if any brick is gone badv7devSanju Rakonde2019-02-052-5/+7
| | | | | | | | | | | | | | | | | | | | | | Problem: get-state command will error out, if any of the underlying brick(s) of volume(s) in the cluster go bad. It is expected that get-state command should not error out, but should generate an output successfully. Solution: In glusterd_get_state(), a statfs call is made on the brick path for every bricks of the volumes to calculate the total and free memory available. If any of statfs call fails on any brick, we should not error out and should report total memory and free memory of that brick as 0. This patch also handles a statfs failure scenario in glusterd_store_retrieve_bricks(). fixes: bz#1672205 Change-Id: Ia9e8a1d8843b65949d72fd6809bd21d39b31ad83 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>

| | | | | | | | | | | | | | | 'configparser' is backported to python2 and can be installed using pip (pip install configparser). So trying to import 'configparser' first and later 'ConfigParser' can cause issues w.r.t unicode strings. Always try importing 'ConfigParser' first and then 'configparser'. This solves python2/python3 compat issues. Change-Id: I2a87c3fc46476296b8cb547338f35723518751cc fixes: bz#1671637 Signed-off-by: Kotresh HR <khiremat@redhat.com>

* mount/fuse: expose auto-invalidation as a mount optionRaghavendra Gowdappa2019-02-0210-10/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Auto invalidation is necessary when same (meta)data is shared/access across multiple mounts. However, if (meta)data is not shared, all relevant I/O goes through the cache of single mount and hence is coherent with (meta)data on bricks always. So, fuse-auto-invalidation can be disabled for this case which gives a huge performance boost for workloads that write data and then immediately read the data they just wrote. From glusterfs --help, <snip> --auto-invalidation[=BOOL] controls whether fuse-kernel can auto-invalidate attribute, dentry and page-cache. Disable this only if same files/directories are not accessed across two different mounts concurrently [default: "on"] </snip> Details on how disabling auto-invalidation helped to reduce pgbench init times can be found at [1]. Time taken for pgbench init of scale 8000 was 8340s. That will be an improvement of 86% (59280s vs 8340s) with auto-invalidations turned off along with other optimizations. Just disabling auto-invalidation contributed 56% improvement by reducing the total time taken by 33260s.

| | | | | | | | | | | | | | | | If a fop to create an entry fails on one of the data brick, we mark the pending changelog on the entry on brick for which it was successful. This is done as part of post op phase to make sure that entry gets healed even if it gets renamed to some other path where its parent was not marked as bad. As it happens as part of post op, we should consider thin-arbiter to check if the brick, which was successful, is the good brick or not. This will avoide split brain and other issues.
