[ovirt-users] Fwd: Re: Hosts lost the communication with FC Storage Domains

[VONDRA Alain]

Hello,
Did you try to reboot your oVirt engine ?
Did you make updates before this happen ?
What kind of storage do you use, iSCSI, nfs, etc... ?
Regrads
Alain

Hello,

No luck with this? Awaiting urgent response. Also attached the vdsm and supervdsm logs from one of the hosts.

Please provide guidance to solve this issue.

Hi,

We have a single cluster with 6 Nodes in a single DC and added 4 FC Storage domains. All the while it was working fine, migrations, creation of new VMs everything were working fine. Now, all of a sudden we see the error message "vdsm is unable to communicate with Master domain ......." and all storage domains, including DC are down. But all Hosts are up, all VMs are running without any issues. But migrations stopped, we cannot create new VMs, we cannot start a shutdown VM.

Can someone help us trouble shoot the issue?

By the way, we are running oVirt Version 4.0.1.
