* 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>
* geo-rep: Fix configparser import issueKotresh HR2019-02-051-2/+2
| | | | | | | | | | | | | | | '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>

* glusterd: manage upgrade to current masterAmar Tumballi2019-02-046-20/+18
| | | | | | | | | | | | | | | | | | | | | | Scenarios tested: * Upgrade the node when there are stripe / tiering and regular type of volumes are present. - All volumes are started fine (as the change was not on brick volfile) - For tier, the functionality may not even work, as changetimerecorder is not present. - 'gluster volume info' properly shows as 'NOT SUPPORTED' for stripe and tier type of volume. * Upgrade in a rolling upgrade scenario, where an old version is able to connect to higher master. - on a normal volume, if the volfile-server was new, the newer client volfiles needed to have utime xlator conditionally. - with this one change, all other changes seem to work fine.

* cluster/dht: Do not use gfid-req in fresh lookupN Balachandran2019-02-022-8/+60
| | | | | | | | | | | | Fuse sets a random gfid-req value for a fresh lookup. Posix lookup will set this gfid on entries with missing gfids causing a GFID mismatch for directories. DHT will now ignore the Fuse provided gfid-req and use the GFID returned from other subvols to heal the missing gfid.

* 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.

* core: make gf_thread_create() easier to useXavi Hernandez2019-02-019-82/+110
| | | | | | | | | | | | | | This patch creates a specific function to set the thread name using a string format and a variable argument list, like printf(). This function is used to set the thread name from gf_thread_create(), which now accepts a variable argument list to create the full name. It's not necessary anymore to use a local array to build the name of the thread. This is done automatically.

* cluster/thin-arbiter: Consider thin-arbiter before marking new entry changelogAshish Pandey2019-02-015-25/+103
| | | | | | | | | | | | | | | | 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.

* core: heketi-cli is throwing error "target is busy"Mohit Agrawal2019-01-315-6/+5
| | | | | | | | | | | | | | | | | | | | Problem: When rpc-transport-disconnect happens, server_connection_cleanup_flush_cbk() is supposed to call rpc_transport_unref() after open-files on that transport are flushed per transport.But open-fd-count is maintained in bound_xl->fd_count, which can be incremented/decremented cumulatively in server_connection_cleanup() by all transport disconnect paths. So instead of rpc_transport_unref() happening per transport, it ends up doing it only once after all the files on all the transports for the brick are flushed leading to rpc-leaks.

* readdir-ahead: do not zero-out iatt in fop cbkRavishankar N2019-01-312-20/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | ...when ctime is zero. ia_type and ia_gfid always need to be non-zero for things to work correctly. Problem: Commit c9bde3021202f1d5c5a2d19ac05a510fc1f788ac zeroed out the iatt buffer in the cbks of modification fops before unwinding if the ctime in the buffer was zero. This was causing the fops to fail: noticeable when AFR's 'consistent-metadata' option was enabled. (AFR zeros out the ctime when the option is set. See commit 4c4624c9bad2edf27128cb122c64f15d7d63bbc8). Fixes: -Do not zero out the ia_type and ia_gfid of the iatt buff under any circumstance. -Also, fixed _rda_inode_ctx_update_iatts() to always update these values from the incoming buf when ctime is zero. Otherwise we end up with zero ia_type and ia_gfid the first time the function is called *and* the incoming buf has ctime set to zero. fixes: bz#1670253 Reported-By:Michael Hanselmann <public@hansmi.ch> Change-Id: Ib72228892d42c3513c19fc6dfb543f2aa3489eca Signed-off-by: Ravishankar N <ravishankar@redhat.com>

* features/sdfs: disable by defaultAmar Tumballi2019-01-292-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the feature enabled, some of the performance testing results, specially those which create millions of small files, got approximately 4x regression compared to version before enabling this. On master without this patch: 765 creates/sec On master with this patch : 3380 creates/sec Also there seems to be regression caused by this in 'ls -l' workload. On master without this patch: 3030 files/sec On master with this patch : 16610 files/sec This is a feature added to handle multiple clients parallely operating (specially those which race for file creates with same name) on a single namespace/directory. Considering that is < 3% of Gluster's usecase right now, it makes sense to disable the feature by default, so we don't penalize the default users who doesn't bother about this usecase. Also note that the client side translators, specially, distribute, replicate and disperse already handle the issue upto 99.5% of the cases without SDFS, so it makes sense to keep the feature disabled by default.

In some cases, moved different code that was not needed to be under lock (for example, taking time, or malloc'ing) to be executed before taking the lock.

* socket: fix issue on concurrent handle of a socketZhang Huan2019-01-281-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Found an issue on concurrent invoke of event handler to the same socket fd, causing memory corruption. This issue arises after applying commit "socket: Remove redundant in_lock in incoming message handling" that removes priv->in_lock to serialize socket read. The following call sequence describes how concurrent socket event handle happens. thread 1 thread 2 thread 3 epoll_wait() return (slot->in_handler is 0) call select_on_epoll() and epoll_ctl() on fd epoll_wait() return slot->in_handler++ (slot->in_handler is 1) slot->in_handler++ (slot->in_handler is 2) call handler() call handler() Fix this issue by skip invoke of handler if there is already a handler inprogress.

* features/shard: Ref shard inode while adding to fsync listKrutika Dhananjay2019-01-242-8/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: Lot of the earlier changes in the management of shards in lru, fsync lists assumed that if a given shard exists in fsync list, it must be part of lru list as well. This was found to be not true. Consider this - a file is FALLOCATE'd to a size which would make the number of participant shards to be greater than the lru list size. In this case, some of the resolved shards that are to participate in this fop will be evicted from lru list to give way to the rest of the shards. And once FALLOCATE completes, these shards are added to fsync list but without a ref. After the fop completes, these shard inodes are unref'd and destroyed while their inode ctxs are still part of fsync list. Now when an FSYNC is called on the base file and the fsync-list traversed, the client crashes due to illegal memory access. FIX: Hold a ref on the shard inode when adding to fsync list as well. And unref under following conditions: 1. when the shard is evicted from lru list 2. when the base file is fsync'd 3. when the shards are deleted.

| | | | | | | | | | | | | | In automatic Splitbrain resolution when favorite child policy is set as size, split brain resolution must not work for directories. Currently, if a directory is in split brain with both copies having same size, the source is selected arbitrarily and healed. fixes: bz#1655050 Change-Id: I5739498639c17c89874cc577362e543adab55f5d Signed-off-by: Sheetal Pamecha <sheetal.pamecha08@gmail.com>

* core: Feature added to accept CidrIp in auth.allowRinku Kothiya2019-01-188-15/+79
| | | | | | | | | | | | | | | Added functionality to gluster volume set auth.allow command to accept CIDR IP addresses. Modified few functions to isolate cidr feature so that it prevents other gluster commands such as peer probe to use cidr format ip. The functions are modified in such a way that they have an option to enable accepting of cidr format for other gluster commands if required in furture. updates: bz#1138841 Change-Id: Ie6734002a7078f1820e5df42d404411cce945e8b Credits: Mohit Agrawal Signed-off-by: Rinku Kothiya <rkothiya@redhat.com>
* lock: Add fencing supportSusant Palai2019-01-1710-122/+1029
| | | | | | | | | | | | | | | | | design reference: https://review.gluster.org/#/c/glusterfs-specs/+/21925/ This patch adds the lock preempt support. Note: The current model stores lock enforcement information as separate xattr on disk. There is another effort going in parallel to store this in stat(x) of the file. This patch is self sufficient to add fencing support. Based on the availability of the stat(x) support either I will rebase this patch or we can modify the necessary bits post merging this patch.

| | | | | | | | | | | | | | Problem: When geo-rep is configured as hybrid crawl directory renames are not synced to the slave. Solution: Rename sync of directory was failing due to incorrect destination path calculation. During check for existence on slave we miscalculated realpath. <host:brickpath/dir>.
