I am running Citrix Xenserver 5.6 and unfortunately suffered a fault with both of the disks that I have in this server! The faulty disks have been fixed but I am suffering 2 problems from this original issue. Since the disks have been replaced I have been unable to start 3 of the 5 VMs on there (all Windows 2008R2). The error I get is "The SR backed failed to complete the oepration". I've yet to find a way around this issue but I have backups so attempted to recover from a backup and delete the broken VM. This worked for me without problems so I removed the older VM and went to restore the next one. The problem I now have is that there is not enough disk space to recover from backup for the other VMs. I have tried the solution as suggested by Ctirix but this does not work for me (http://support.citrix.com/article/CTX123400
Any ideas on this would be great. Fortunately this is just a test server so nothing too serious but would very much like to be able to get these VMs back and running asap.
Thanks in advance.
