[Bacula-users] Problem changing tapes due to inconsistency between 'list media' and 'query catalog'?
2010-01-28 04:44:59
Dear all
In our current setup, Bacula does not seem to automatically load the correct tape in the drive for its backups. We did specify the correct autochanger options in the storage daemon conf file and made sure the device uses the autochanger.
When we execute the 'list media' command in bconsole, we get the following output:
Automatically selected Catalog: ClientDB
Using Catalog "ClientDB"
Pool: Default
+---------+------------+-----------+---------+----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| MediaId | VolumeName | VolStatus | Enabled | VolBytes | VolFiles | VolRetention | Recycle | Slot | InChanger | MediaType | LastWritten |
+---------+------------+-----------+---------+----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
| 1 | 426BBL | Append | 1 | 26,842,862,592 | 65 | 31,536,000 | 1 | 0 | 1 | LTO-4 | 2010-01-28 06:00:11 |
+---------+------------+-----------+---------+----------------+----------+--------------+---------+------+-----------+-----------+---------------------+
from which i derive that Bacula recognizes one pool ('Default') with one associated volume, that is currently in the autochanger.
But the 'query catalog' command (we use the mysql db) seems not to know about the volume in the autochanger:
*query catalog
Automatically selected Catalog: ClientDB
Using Catalog "ClientDB"
Available queries:
1: List up to 20 places where a File is saved regardless of the directory
2: List where the most recent copies of a file are saved
3: List last 20 Full Backups for a Client
4: List all backups for a Client after a specified time
5: List all backups for a Client
6: List Volume Attributes for a selected Volume
7: List Volumes used by selected JobId
8: List Volumes to Restore All Files
9: List Pool Attributes for a selected Pool
10: List total files/bytes by Job
11: List total files/bytes by Volume
12: List Files for a selected JobId
13: List Jobs stored on a selected MediaId
14: List Jobs stored for a given Volume name
15: List Volumes Bacula thinks are in changer
16: List Volumes likely to need replacement from age or errors
Choose a query (1-16): 15
No results to list.
In addition, the logs show the following message blocks:
28-Jan 04:00 blade03-sd JobId 19: Invalid slot=0 defined in catalog for Volume "426BBL" on "TS2900" (/dev/nst0). Manual load may be required.
28-Jan 04:00 blade03-sd JobId 19: 3301 Issuing autochanger "loaded? drive 0" command.
28-Jan 04:00 blade03-sd JobId 19: 3302 Autochanger "loaded? drive 0", result: nothing loaded.
28-Jan 04:00 blade03-sd JobId 19: 3301 Issuing autochanger "loaded? drive 0" command.
28-Jan 04:00 blade03-sd JobId 19: 3302 Autochanger "loaded? drive 0", result: nothing loaded.
28-Jan 04:00 blade03-sd JobId 19: Warning: mount.c:219 Open device "TS2900" (/dev/nst0) Volume "426BBL" failed: ERR=dev.c:474 Unable to open device "TS2900" (/dev/nst0): ERR=No medium found
In other words, the catalog does not seem to know about the volumes in the autochanger slots? Could we run a bscan or take other actions to restore consistency between the catalog and the tape library? We already tried the 'update slots' command but that had no effect.
Note that we are just getting started with Bacula soo re-initializing the whole catalog is an option if it would make our setup consistent again.
Many thanks in advance
