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.
