Subject Re: Help: Can't start instances: Db_exn.Uniqueness_constraint_violation
Date Fri, 08 Aug 2014 01:33:19 GMT
Trying to dig a bit deeper here:

The SMLog from my previous email was from my host xen03.  So looks like
this uuid already existed on a different machine and it belongs to an SR
for secondary storage mount of my ubuntu template.  In looking across my
hosts, 3 of the 6 appear to have these.

I looked on xen05 for its SMLog and I am seeing the following that tells me
this vdi should have been detached.  Is this a XS bug or did CS not send
the proper command?
