Dear All,
I’m struggling with this issue since day one and I have not found any solution
for it yet. We use VEEAM to back up our VMs and an OmniOS VM as a CIFS target.
We have one OmniOS VM for internal and one for DMZ. VEEAM Backups to the one
for internal work fine. No problems at all. Backups to the DMZ one fail every
time. I can access the CIFS share just fine from windows. When the backup
starts two or three VMs are backed up and then it fails. I have requested
support from VEEAM and it turns out the same job running against a Windows
server CIFS share works just fine. I couldn’t believe that OmniOS is the
culprit as the CIFS implementation from Illumos is very good. So I setup a new
OmniOS bare-metal server and created a zone for DMZ. I setup a cifs share and
ran the same job. Everything works fine. I compared the settings from both the
VM and the Zone and they are 100% identical. Only difference is one is a VM and
one is a Zone. But since the VEEAM backup to the internal VM has no problems
with the backup, I don’t think virtualization is a problem here. Is there
anywhere I can start investigating further? I would be more than happy to use a
zone instead of a full blown VM but since there is no ISCSI and NFS server
support in a Zone I have to stick with the VM as we need NFS since the VM is
also a datastore for a few VMs.
Any help is really appreciated.
Best Regards,
Oliver
