Cannot mount user disk after system backup

On a rx2600 running VMS 8.3...
We lost a system disk, replaced it, restored it from backup, installed the latest update kit.

Everything ran fine for a week but there were a few disk errors, so we ran a new system backup, replaced the disk yet again, restored the backup and now we get this weird error after boot when trying to mount the user disk. (see below).

Replacing the system disk with the previous one that was getting errors, same problem.

Booting from the upgrade disk, going to DCL, no problem, user disk mounts fine.

After booting up I log into the system account
sho dev dkb200: says "(remote mount)".
so I try to mount it manually:

$ dismount dkb200
%SYSTEM-F-DEVNOTMOUNT, device is not mounted
$ mount/cluster/system dkb200: IVMSUSER
%MOUNT-I-OPRQST, different volume already mounted on this device
%MOUNT-I-OPRQST, Please mount volume IVMSUSER in device _FISH$DKB200:
%MOUNT-I-NOOPR, no operator available to service request
*INTERRUPT*

$ mount/override=id dkb200:
%MOUNT-I-OPRQST, device is already mounted
%MOUNT-I-OPRQST, device _FISH$DKB200: is not available for mounting.
%MOUNT-I-NOOPR, no operator available to service request
*INTERRUPT*

$ dismount dkb200:
%SYSTEM-F-DEVNOTMOUNT, device is not mounted

So mount says it's mounted, dismount says it's not mounted. Any idea what's going on?

Re: Cannot mount user disk after system backup

Is the problem disk still mounted on other
cluster members? If so, I'd vote for
DISMOUNT /ABORT
on all the cluster members where it is.

Cluster members share info, so if one
believes that some volume name is in use
somewhere, then they all tend to believe it.

Otherwise, a little more info about which
disks are where might be useful.

That was it, thanks.

Re: Cannot mount user disk after system backup

This situation is even more annoying when the
disk in limbo is the system disk from which
you're trying to boot. As I recall, you get
some unhelpful message with a hex error code,
and then you need to find a working system
where you can decode the code. (Easier now,
with the Web, than in the old, pre-Web days.)

Fun is where you find it.
