* inodelk-count: Add stats to count the number of lock objectskrad2017-09-136-1/+194
| | | | | | | | | | | | | | | | | | | | | | | | Summary: We want to track the number of locks held by the locks xlator. One of the ways to do it would be to track the total number of pl_lock objects in the system. This patch tracks the total number of pl_lock object and exposes the stat via io-stats JSON dump. Test Plan: WIP, haven't got a pass. Putting the diff to get a sense of this approach would yield what you guys are looking for?

* Remediation for XFS/DIO corruption problem.Jeff Darcy2017-09-1215-24/+669
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new volume option, shd-validate-data. When set, the self-heal code will fetch checksums for regular files along with all the usual xattrs. If the file seems OK but the checksums show a data mismatch, and if there is only one replica that's out of step with the others, then we modify the source/sink calculations to force a heal from one of the agreeing replicas to the odd one out. Combined with a tool to put files into the self-heal index (being developed separately), this provides a very rudimentary kind of scrubbing functionality. Validation is now conditional on the "trusted.glusterfs.validate-status" xattr having the specific value of "suspect" to avoid redoing validation (which is expensive) as we find the same file in multiple bricks' indices. When we decide to take action, we update this xattr to "clean" for copies that were in the majority and "repaired" for the odd one out that gets clobbered. We also copy the about-to-be-clobbered copy into an "orphans" directory to facilitate analysis of corruption patterns. The data goes into ${GFID}.data there, while ${GFID}.link is a symlink to the file's old location.

| | | | | | | | | | | | Summary: These requests haven't been issued, yet alone acknowledged. They would disappear if we crashed, which to the client is indistinguishable from any other kind of disconnection - if indeed the client itself isn't the one that died. So we're completely within our rights to discard these. There are strong hints that such "orphan" requests are part of how we get into the lock-revocation hangs we've been seeing for a while. Even if that theory doesn't pan out, there's no good reason to keep them around clogging up queues and so forth.

* exports: Add a reference count to export_item_t structs and ensure they are ↵Shreyas Siravara2017-09-083-10/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | correctly used Summary: This diff fixes a bug in the NFS daemon where the auth cache would use an export item after it was free'd by the auth params refresh thread. This usually manifests as a crash in production, when exports files are updated by chef. Since each auth cache entry holds a pointer to an export_item_t it makes sense that it should first get a reference to it. Freein'g the export_item_t struct happens only in `exp_item_unref()`, once the reference count has dropped to 0. This diff also fixes a use-after-free bug in the auth-cache, in the insertion path. In _cache_item(), if we find an entry in the dict, we update that entry with a timestamp & ref the export item associated with it. However, if the item already existed and we called old_cache_insert() with the same key, we gave the dict permission to free the old entry. We then end up using that entry. The fix is to use dict_set_static_bin() instead of dict_set_bin() which informs the dict that the pointer we are giving it belongs to us.

The main functional change is locking around the external calls into this module, to prevent some of the races that we've seen.

* performance/io-threads: Add watchdog to cover up a possible thread leakJeff Darcy2017-09-083-16/+213
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: There appears to be a thread leak somewhere, which causes io-threads to run out of threads to process a particular (priority-based) queue. The leak should obviously be fixed, but that might take a while and the consequences until then are severe - a brick essentially going offline without the courtesy of actually dying. This patch adds a watchdog that checks for stuck queues, and adds threads to break the deadlock. The same thing done manually on one afflicted cluster caused brick CPU usage to drop from 2600% to 400%, with latency quickly returning to normal. The controlling option is performance.iot-watchdog-secs, which is the number of seconds we'll watch for a non-empty queue with no items being dequeued. That's our signal to add a thread. A value of zero (the default) disables this watchdog feature. This is a port of D5177414 to 3.8. Test Plan: All the usual tests to determine safety. Use gdb to hack priv->queue_sizes to a non-zero value. This will make it look like the queue is non-empty, but since it does in fact have zero items there will be no dequeues. After watchdog-secs seconds, this should add a thread, with a corresponding entry in the brick log.

* features/namespace: Add namespace xlator and link into brick graphMichael Goulet2017-09-0711-1/+1520
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This translator tags namespaces with a unique hash that corresponds to the top-level directory (right under the gluster root) of the file the fop acts on. The hash information is injected into the call frame by this translator, so this namespace information can later be used to do throttling, QoS and other namespace-specific stats collection and actions in later xlators further down the stack. When the translator can't find a path directly for the fd_t or loc_t, it winds a GET_ANCESTRY_PATH_KEY down to the posix xlator to get the path manually. Caching this namespace information in the inode makes sure that most requests don't need to recalculate the hash, so that typically fops are just doing an inode_ctx_get instead of the more expensive code paths that this xlator can take. Right now the xlator is hard-coded to only hash the top-level directory, but this could be easily extended to more sophisticated matching by modification of the parse_path function. Test Plan: Run `prove -v tests/basic/namespace.t` to see that tagging works.

Negative numbers indicate that quorum has been lost and show the number of bricks that must be brought online to restore quorum. Additionally, I found that the code contained both afr_have_quorum() and afr_has_quorum(), which were mostly cut-n-pasted copies of each other, but with subtle differences. Mercifully, afr_have_quorum() was totally unused, so I nuked it in passing. This is a port of D4089969 to 3.8. Test Plan: Run, observe stats output. Kill brick, observe proper change. fb-smoke.
