[Gluster-users] afr-self-heald.c:479:afr_shd_index_sweep
Hi all,
for the upgrade I followed this procedure:
* put node in maintenance mode (ensure no client are active)
* yum versionlock delete glusterfs*
* service glusterd stop
* yum update
* systemctl daemon-reload
* service glusterd start
* yum versionlock add glusterfs*
* gluster volume heal vm-images-repo full
* gluster volume heal vm-images-repo info
on each server every time I ran 'gluster --version' to confirm the
upgrade, at the end I ran 'gluster volume set all cluster.op-version
30800'.
Today I've tried to manually kill a brick process on a non critical
volume, after that into the log I see:
[2017-06-29 07:03:50.074388] I [MSGID: 100030] [glusterfsd.c:2454:main]
0-/usr/sbin/glusterfsd: Started running /usr/sbin/glusterfsd version

49163 --xlator-option iso-images-repo-server.listen-port=49163)
I've checked after the restart and indeed now the directory
'entry-changes' is created, but why stopping the glusterd service has
not stopped also the brick processes?
Now how can I recover from this issue? Restarting all brick processes is
enough?
Greetings,
Paolo Margara
