[ovirt-users] Gluster 3.7.8 from ovirt-3.6-glusterfs-epel breaks vdsm ?

[Matteo]

Hi,

today I update one node os, in the updates gluster client
packages where upgraded from 3.7.6-1.el7, centos-ovirt36 repository
to 3.7.8-1.el7, ovirt-3.6-glusterfs-epel and after reboot
the node was marked not operational.

looking into the logs, vdsm was failing to get gluster volume information.

the command (ovirt-storage is the gluster storage where the hosted engine is kept)

gluster --mode=script volume info --remote-host=gluster1 ovirt-storage --xml

was failing, returning error 2 (and no output)

doing yum downgrade on gluster client packages (back to 3.7.6-1.el7, centos-ovirt36) fixed everything.

Data nodes are running glusterfs 3.7.6-1.el7.

The funny thing is that from the ovirt I was able to manually mount the glusterfs shares,
only the volume info command was failing, thus breaking vdsm.

Any hint?

regards,
Matteo
