We have an ovirt system with 3 clusters, all running centos7.
ovirt engine is running on separate host,

2 of the clusters are running newer version of ovirt, 3 nodes each,
ovirt-engine-4.0.3-1.el7.centos.noarch, glusterfs-3.7.16-1.el7.x86_64,
vdsm-4.18.11-1.el7.centos.x86_64.
1 cluster is still running the older version,
ovirt-engine-3.6.4.1-1.el7.centos.noarch.
Which ioprocess version?
Yes we are in the process of upgrading the whole system to ovirt4.0, but
takes time....
One of the 2 clusters running ovirt4 is complaining of timeouts, vdsm
talking to gluster. No warnings on the 2 other clusters.

This warning is harmless, it means that ioprocess thread did not start
in 1 second.
This probably means that the host is overloaded, typically new threads start
instantly.
Anyway I think we are using too short timeout. Can you open an ioprocess
bug for this?
