The switches above our environment had some VPC issues and the port channels
went offline. The ports that had issues belonged to 2 of the gfs nodes in our
environment. We have 3 storage nodes total with the 3rd being the arbiter. I
wound up rebooting the first 2 nodes and everything came back happy. After a
few hours I noticed that the storage was up but complaining about being out of
sync and needing healing. Within the hour I noticed a VM had paused itself due
to storage issues. This is a small environment, for now, with only 30 VM's. I
am new to Ovirt so this is uncharted territory for me. I am tailing some logs
and things look sort of normal and google is sending me down a wormhole.
If I run "gluster volume heal cps-vms-gfs info" this number seems to be
changing pretty regularly. Logs are showing lots of entries like this:
[2018-11-08 21:55:05.996675] I [MSGID: 114047]
[client-handshake.c:1242:client_setvolume_cbk] 0-cps-vms-gfs-client-1: Server
and Client lk-version numbers are not same, reopening the fds
[2018-11-08 21:55:05.997693] I [MSGID: 108002] [afr-common.c:5312:afr_notify]
0-cps-vms-gfs-replicate-0: Client-quorum is met
[2018-11-08 21:55:05.997717] I [MSGID: 114035]
[client-handshake.c:202:client_set_lk_version_cbk] 0-cps-vms-gfs-client-1:
Server lk version = 1
I guess I am curious what else should I be looking for? Is this just taking
forever to heal? Is there something else I can run or I should do to verify
things are actually getting better? I ran an actual heal command and it cleared
everything for a few seconds and then the entries started to populate again
when I did the info command.
