urgent help needed: primary storage became unplugged after
xenserver roboot
Hi, All:
I need some urgent help in restoring my CS instance (version 4.3.1).
After patching xenserver 6.2, I rebooted the pool master (I have two xen hypervisors). After the pool master comes back, the SR for the primary storage became “unplugged”, and shown as broken in XenCenter. The volume is not mounted on pool master host any more.
How do I get it back without losing any data ?
Thanks for all helps.

It can be fixed. I too had same issue when I did the patch on xenserver.
The problem is after you apply patch you might lost the mount point
information for example
cat /opt/cloud/bin/heartbeat
/var/run/sr-mount/42d66763-9251-ab84-8717-8f5e9dcedc09
So just simply add mount point information on /opt/cloud/bin/heartbeat.
Where can I find that?
cd /var/run/sr-mount/
ls -ltrh
total 60K
drwxr-xr-x 3 root root 56K Jan 8 09:01 42d667 (you might see a log
directory) so place that into the /opt/cloud/bin/heartbeat
after that mount manually and do the rescan in xencenter.
You issue might get resolve.
Thanks,
Keerthi

We had a similar problem before. It turned out to be a unsupported combination of cloudstack + xenserver (we did run 4.2.1 with xenserver 6.2 sp1) . Please check you have all required patches applied on the Xen box.
Best regards

I seem to recal there were some clouds tack files overwritten with updates. I'd try redeploy it in cloudstack. I would also take a pool backup first.
Also check the XS logs for errors. /var/log/messages and /var/log/SMlog

[SOLVED]: urgent help needed: primary storage became unplugged
after xenserver roboot
Posted by Yiping Zhang <yz...@marketo.com>.
Doing ³repair² Ÿrom xencenter give me following error:
Error code: SR_BACKEND_FAILURE_73
Error parameters: , NFS mount error [opterr=mount failed with return code
32],
Looking at /var/log/SMlog, I see a NFS mount error, because the cmd tried
to mount "server:/path/<uuid>² instead of just ³server:/path² !
So I manually mounted NFS volume on the hypervisor, then did a ³repair² in
XenCenter, and the SR became available !
Looks to me XenCenter repair has a bug!!!

I believe you could try repair from XenCenter. It gets the PBD get plugged most often than not.
