I have inherited a xenserver setup running 6.0. There is a storage pool set up with two host servers (a bad idea to start with I gather), 8 vms and several SRs. I recently had one of the hosts fail and now it can't see any of the SRs that used to be attached, including the dvd-rom drive. As a result, I cant restart any of the vms that were not on the HA plan (the HA protected vms are still running on the other host, fortunately).
When trying to reconnect the host to one of the SRs by doing a xe pbd-plug uuid=the_uuid_for_local_storage for example, I get the following error in response:
message: Failure("Storage_access failed with: INTERNAL_ERROR: [ Sm.Unknown_driver(\"lvm\") ]")
Attempts to plug the other SRs fail in the same way with the driver name varying depending on the type of storage.
A web search failed to bring up anything matching this particular error and the documentation hasn't revealed any clues either. Being new to xenserver, I'm a bit lost as to how to troubleshoot this problem. Any help would be greatly appreciated.
