After glusterfs 3.7.11, around 4-5 bugs were found in sharding and
replicate modules and fixed, some of them causing the VM(s) to pause. Could
you share the glusterfs client logs from around the time the issue was
seen? This will help me confirm it's the same issue, or even debug further
any vms at any point before or after the upgrade?

Couple of things:
1. Like Darrell suggested, you should enable stat-prefetch and increase
client and server event threads to 4.
# gluster volume set performance.stat-prefetch on
# gluster volume set client.event-threads 4
# gluster volume set server.event-threads 4
2. Also glusterfs-3.10.1
No, you don't need to do any of that. Just executing volume-set commands is
sufficient for the changes to take effect.

No. It's just that in the internal testing that was done here, increasing
the thread count beyond 4 did not improve the performance any further.

This seems like a case of O_DIRECT reads and writes gone wrong, judging by
the 'Invalid argument' errors.
The two operations that have failed on gluster bricks are:

As for the fsync hang and subsequent IO errors, it seems a lot like
https://bugzilla.redhat.com/show_bug.cgi?id=1497156 and Paolo Bonzini from
qemu had pointed out that this would be fixed by the following commit:
Adding Ravi who works on replicate component to hep resolve the mismatches.

Could you share the gluster mount and brick logs? You'll find them under
Also, what's the version of gluster you're using?
Also, output of `gluster volume info `?

Gluster's write-behind translator by default buffers writes for flushing to
disk later, *even* when the file is opened with O_DIRECT flag. Not honoring
O_DIRECT could mean a reader from another client could be READing stale
data from bricks because some WRITEs may not yet be flushed to disk.

So in our internal tests (with nvme ssd drives, 10g n/w), we found read
performance to be better with choose-local
disabled in hyperconverged setup. See
https://bugzilla.redhat.com/show_bug.cgi?id=1566386 for more information.
With choose-local off, the read replica is chosen randomly (based on

Agreed. Please share the bug report when you're done filing it. In
addition to the logs Nir requested, include gluster version and the
`gluster volume info` output in your report.
We'll take the discussion forward on the bz.

Yes, so the bug has been fixed upstream and the backports to release-7 and
