We have a xenserver 6.0 environment with an iscsi SR that has had an RAID problem, disk replaced, and now VMs with Windows 2008 R2 have strange errors. Probably because the underlying SR has bad blocks.
Most of the VMs run fine, perhaps the parts of the windows file system that has been affected is not used in the VM - we are lucky.
So, we try to use a VM backup software to pull the VMs and store them elsewhere, but the snapshot hangs on 56 % probably cause it reaches something bad on the drive. Is there anyway to get these VMs snapped and extracted?
Any ideas? We´ve seen the Acronis software can do this, but is it less sensitive to these errors.
