Subject Re: Snapshot and Template Issue with VMWare
Date Fri, 22 Feb 2013 15:12:24 GMT
Hi,

I should have said that we have a working XenServer cluster within that 
zone, so I would be suprised the issue is with the SSVM itself...

Thanks!

and VMWare 5.  The snapshot of a volume appears to be working fine on the VMWare side (I can
see it in the vCenter task list), but the snapshot cannot be copied to the secondary storage
NFS share.  The log file is a bit fuzzy about the exact cause, I do see couple errors. Maybe
someone can shed some lights.  Thanks in advance, and let me know if I should open a case
on the BTS!
