Dear all,
we would like to describe the situation that we have and that does not
solve since a long time, that means after many minor
and major upgrades of GlusterFS
We use a KVM environment for VMs for glusterfs and host servers are
updated regularly. Hosts are disomogeneous hardware,
but configured with same characteristics.
The VMs have been also harmonized to use the virtio drivers where
available for devices and resources reserved are the same
on each host.
Physical switch for hosts has been substituted with a reliable one.
Probing peers has been and is quite quick in the heartbeat network and
communication between the servers for apparently has no issues on
disruptions.
And I say apparently because what we have is:
- always pending failed heals that used to resolve by a rotated reboot
of the gluster vms (replica 3). Restarting only
glusterfs related services (daemon, events etc.) has no effect, only
reboot brings results
- very often failed heals are directories
We lately removed a brick that was on a vm on a host that has been
entirely substituted. Re-added the brick, sync went on and
all data was eventually synced and started with 0 pending failed heals.
Now it develops failed heals too like its fellow
bricks. Please take into account we healed all the failed entries
(manually with various methods) before adding the third brick.
After some days of operating, the count of failed heals rises again, not
really fast but with new entries for sure (which might solve
with rotated reboots, or not).
We have gluster clients also on ctdbs that connect to the gluster and
mount via glusterfs client. Windows roaming profiles shared via smb
become frequently corrupted,(they are composed of a great number small
files and are though of big total dimension). Gluster nodes are
formatted with xfs.
Also what we observer is that mounting with the vfs option in smb on the
ctdbs has some kind of delay. This means that you can see the shared
folder on for example
a Windows client machine on a ctdb, but not on another ctdb in the
cluster and then after a while it appears there too. And this frequently st
This is an excerpt of entries on our shd logs:

How are he clients mapped to real hosts in order to know on which one´s
logs to look at?
We would like to go by exclusion to finally eradicate this, possibly in
a conservative way (not rebuilding everything) and we
are becoming clueless as to where to look at as we also tried various
options settings regarding performance etc.

Again, sorry for the long post. We would be happy to have this solved as
we are excited using glusterfs and we would like to go back to having a
stable configuration.
We always appreciate the spirit of collaboration and reciprocal help on
this list.
