Unable to unmount snapshot mount point snapshot mountpoint during cleanup of snapshot 'snapshot' of volume 'volume'. Error is 'error'. Operation will continue. Please manually unmount, remove the snapshot mount point directory and delete the snapshot after backup is completed.

Explanation

During the termination phase of TSM client operation, it was not possible to unmount the snapshot for some reason. However, TSM operation was completed successfully.

System action

Processing continues, and the unmount error is ignored.

User response

Please manually cleanup the snapshots as follows: Query the snapshot: snapshot -q -c: <source FS>. Snapshot name will be of the format: tsmxxxxxxxxxx. Check if it is mounted: df -k | grep tsmxxxxxxxxxx. Unmount the snapshot: umount -f tsmxxxxxxxxxx. Remove snapshot mount point: rmdir tsmxxxxxxxxxx. Delete the snapshot: snapshot -d /dev/tsmxxxxxxxxxx. If snapshot delete fails with "Device Busy" or some other error, unmount the snapshot source filesystem: umount -f <source FS>. Retry snapshot delete: snapshot -d /dev/tsmxxxxxxxxxx. Check if any logical volumes are remaining: ls -l /dev/tsm*. Remove any remaining logical volumes: rmlv -f tsmxxxxxxxxxx. Remount source file system, if previously unmounted: mount <source FS>.
