We issue the following command to take snapshot for backups each night
DATA_SNAP=`/usr/sbin/fssnap -F ufs -o
bs=/snapshots/backing_stores/data_snapshot,unlink /data`
/usr/sbin/mount -F ufs -o ro $DATA_SNAP /snapshots/data
Normally, during the tape backup process, there is not a lot of activity on
/data.
After the tape backup process is finished, the snapshot is removed
/usr/sbin/umount /snapshots/data
fssnap -d /data
However, during an application upgrade process, a great deal of data was
being written and rewritten to /data while at the same time,
a temporary backup copy of the data in /snapshots/data was being written to
another disk.
During the copy process, an error occurred stating that the device
/snapshots/data/filename was an invalid device. Inspection of
/snapshots/data showed no files.
At the same time, a "df -k "on the /snapshots mount showed it was at 100%
capacity.
/dev/md/dsk/d90 35293316 35293263 0 100% /snapshots
I accepted that the snapshot was lost and tried to delete it using fssnap -d
/data, but received the error:
fssnap: ioctl: error 2: No such file or directory
fssnap -i also shows nothing.
How can I delete this snapshot if I can't reference it?
The only thing I've been able to find is that the snapshot would be delete
by a reboot, but this is not the option I was hoping for at this time.
