* glusterd: move new feature (tiering) enum op to the last of the arrayGaurav Kumar Garg2015-11-031-2/+5
| | | | | | | | | | | | | | | | | | | | Currently new feature tiering have GD_OP_DETACH_TIER and GD_OP_TIER_MIGRATE enum in the middle of the glusterd_op_ enum array. In multi nodes cluster when one of the node upgraded from lower version to higher version and upon executing command can end up in a mismatch in enum ops at the receiver ends causing command execution fail. Fix is to put every new feature glusterd operation enum code to last of the enum array.

| | | | | | | | | | | | | | | | | The tier query parsing code was using fscanf to read each record. As space is a delimiter for fscanf, filenames containing spaces caused the parsing to return unexpected values causing various issues in the tier process, including crashes due to buffer overflows.

| | | | | | | | | | | | | | | | | | | | | | | The snap-max-hard-limit being displayed in the volume info currently is propagated from system's snap-max-hard-limit as that is a global option common for all volumes, and hence ends up showing the system's snap-max-hard-limit. We should not be displaying snap-max-hard-limit and snap-max-soft-limit in the volume info at all, as these are snap config options and should be set and displayed via snap config command. Modified bug-1113476.t to test the same behaviour.

* debug/io-stats: Add FOP sampling featureRichard Wareing2015-11-0114-35/+864
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: - Using sampling feature you can record details about every Nth FOP. The fields in each sample are: FOP type, hostname, uid, gid, FOP priority, port and time taken (latency) to fufill the request. - Implemented using a ring buffer which is not (m/c) allocated in the IO path, this should make the sampling process pretty cheap. - DNS resolution done @ dump time not @ sample time for performance w/ cache - Metrics can be used for both diagnostics, traffic/IO profiling as well as P95/P99 calculations - To control this feature there are two new volume options: diagnostics.fop-sample-interval - The sampling interval, e.g. 1 means sample every FOP, 100 means sample every 100th FOP diagnostics.fop-sample-buf-size - The size (in bytes) of the ring buffer used to store the samples. In the even more samples are collected in the stats dump interval than can be held in this buffer, the oldest samples shall be discarded. Samples are stored in the log directory under /var/log/glusterfs/samples. - Uses DNS cache written by sshreyas@fb.com (Thank-you!), the DNS cache TTL is controlled by the diagnostics.stats-dnscache-ttl-sec option and defaults to 24hrs. Test Plan: - Valgrind'd to ensure it's leak free - Run prove test(s) - Shadow testing on 100+ brick cluster Change-Id: I9ee14c2fa18486b7efb38e59f70687249d3f96d8 BUG: 1271310 Signed-off-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-on: http://review.gluster.org/12210 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* snapshot : copying nfs-ganesha export fileJiffin Tony Thottan2015-10-304-0/+213
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While taking snapshot, the export file used by the volume should copy to snap directory. So that when restore of snapshot happens, the volume can retain all its configuration for exporting via nfs-ganesha. The export file is stored at "/etc/ganesha/export" in the following format "export.<volname>.conf" The fix handles given cases in the following manner : case a: The nfs-ganesha(global) is ON during snapshot and restore. i.) Volume was exported during snapshot. When we restore snapshot, then volume should be exported back with old configuration file. ii.) Volume was unexported during snapshot. When we restore snapshot, then volume should unexported again. case b: The nfs-ganesha is ON during snapshot and OFF during restore Volume was exported during snapshot. When we restore snapshot, the conf will be copied to corresponding location and if nfs-ganesha enabled again, then volume will be exported. For the clones, export conf file will created in /etc/ganesha/export and then export it via ganesha.

Major impact: Any failure in the gf_defrag_process_dir means there are files left unmigrated in the directory. Fix-layout(setxattr) failure will impact it's child subtree i.e. the child subtree will not be rebalanced. Settle-hash (commit-hash)failure will trigger lookup_everywhere for immediate children until the next commit-hash. Note: Remove-brick opertaion is still sensitive to any kind of failure.

* features/changelog: record mknod if tier-dht linkto is setSaravanakumar Arumugam2015-10-271-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a series of patches which aims to fix geo-replication in a Tiering Volume. Problem: Consider, a file is placed in volume initially and then hot tier is attached. During any operation on the file, due to lookup a linkto file is created in hot tier. Now, any namespace operation carried out on the file is recorded in both cold and hot tier. There is a room for races when both changelogs are replayed. Solution: So, We are going to replay (namespace related)operations only in the hot tier. Why? a. If the file is directly placed in Hot tier, all fops will be recorded in HOT tier. b.

* tests: fix timeout in mount-nfs-auth.tJeff Darcy2015-10-271-11/+16
| | | | | | | | | | | | | | | | | | | | | The mount timeout was too short. The normal configuration-change path (construct graph, call reconfigure) and the auth-refresh path might in effect run serially. Therefore we have to wait for the *sum* of those two intervals. As with all too-short-timeout problems, the result was that the test would run fine most of the time. However, it has caused spurious failures on my own patches a half dozen times, and I have a half dozen other emails about it nuking other people's as well (most often but not always on NetBSD). The fix, obviously, is to calculate and use the right timeout value for NFS mount actions. Other actions and timeouts have been left alone.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Approach: Shard xlator on slave side is by passed for all the fops to geo-rep mount. So each shard on master is considered as a separate file for geo-rep and it syncs them separately on to slave. The extended attribute in which shard maintains the size is also synced from master and shard on slave doesn't calculate by itself. Pre-requisites: 1. If master is sharded volume, slave also should be sharded. 2. Slave's shard configurations should be same as master. 3. Geo-rep config of xattr sync should not be disabled.

* geo-rep: Avoid cold tier bricks during ENTRY operationSaravanakumar Arumugam2015-10-264-5/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a series of patch which aims to fix geo-replication in a Tiering Volume. Problem: Consider, a file is placed in volume initially and then hot tier is attached. During any operation on the file, due to lookup a linkto file is created in hot tier. Now, any namespace operation carried out on the file is recorded in both cold and hot tier. There is a room for races when both changelogs are replayed. Solution: So, We are going to replay (namespace related)operations only in the hot tier. Why? a. If the file is directly placed in Hot tier , all fops will be recorded in HOT tier. b. If the file is already present in Cold tier, and if any fop is carried out, it creates linkto file in Hot tier. Now, operations like UNLINK, RENAME are captured in Hot tier(by means of linkto file). This way, we can get both tier's operation in HOT tier itself. Now, once the file is demoted to COLD tier, any namespace operation carried out on the cold tier can be avoided as we directly RECORD the same in HOT tier. How? 1. Check whether the brick is cold tier and skip ENTRY operation. 2. Also, if it is cold tier brick, use Xsync(which is used during initial run). This will help in getting all cold tier bricks changes using File System crawl and helps in avoiding races with hot tier brick(which can happen if historychangelog used in cold tier brick).

* mount/fuse: use a queue instead of pipe to communicate with threadRaghavendra G2015-10-263-63/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | doing inode/entry invalidations. Writing to pipe can block if pipe is full. This can lead to deadlocks in some situations. Consider following situation: 1. Kernel sends a write on an inode. Client is waiting for a response to write from brick. 2. A lookup happens on behalf of different application/thread on the same inode. In response, mdc tries to invalidate the inode. 3. fuse_invalidate_inode is called. It writes a invalidation request to pipe. Another thread which reads from this pipe writes the request to /dev/fuse. The invalidate code in fuse-kernel-module, tries to acquire lock on all pages for the inode and is blocked as a write is in progress on same inode (step 1) 4. Now, poller thread is blocked in invalidate notification and cannot receive any messages from same socket (on which lookup response came). But client is expecting a response for write from same socket (again step1) and we've a deadlock. The deadlock can be solved in two ways: 1. Use a queue (and a conditional variable for notifications) to pass invalidation requests from poller to invalidate thread. This is a variant of using non-blocking pipe, but doesn't have any limit on the amount of data (worst case we run out of memory and error out). 2. Allow events from sockets, immediately after we read one rpc-msg. Currently we disallow events till that rpc-msg is read from socket, processed and handled by higher layers. That way we won't run into these kind of issues. Also, it'll increase parallelism in way of reading from sockets. This patch implements solution 1 above.

* libglusterfs: replace default functions with generated versionsJeff Darcy2015-10-2212-3428/+1853
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replacing repetitive code like this with code generated from a more compact "canonical" definition carries several advantages. * Ease the process of adding new fops (e.g. GF_FOP_IPC). * Ease the process of making global changes to existing fops (e.g. adding "xdata"). * Ensure strict consistency between all of the pieces that must be compatible with each other, through both kinds of changes. What we have right now is just a start. The above benefits will only truly be realized when we use the same definitions to generate stubs, syncops, and perhaps even parts of gfapi or glupy. This same infrastructure can also be used to reduce code duplication and potential for error in many of our translators. NSR already uses a similar technique, using a few hundred lines of templates to generate a few *thousand* lines of code. The ability to make a global "aspect" change (e.g. to quorum checking) in one place instead of seventy has already been demonstrated there. Other candidates for code generation include the AFR/EC transaction infrastructure, or stub creation/resumption in io-threads.
