Hello there,

I am facing the following problem from time to time one of the hypervisor (there are 3 of them)s is rebooting, I am using ovirt-release42-4.2.1-1.el7.centos.noarch and glsuter as a storage backend (glusterfs-3.12.5-2.el7.x86_64).

I am suspecting gluster because of the e.g. message bellow from one of the volumes,

Could you please help and suggest to which direction should investigation go?

Thanks in advance

Cheers

Erekle
