Help! Bacula is unable to use one of the two drives in our LTO2 (Dell
Powervault 132) autochanger.
I've been fine-tuning my bacula config, and went from having all backups going
to a default pool to separate pools for incrementals, full, and archive backups.
Previously, backups worked fine with the autochanger, writing to both tape
drives at once.
I haven't made any changes to the "Storage" resource in the bacula-dir.conf, or
to the bacula-sd.conf at all. Only the Job definitions, Pools, and Schedules
were changed in the bacula-dir file.
I do not believe that this is a configuration issue, just that bacula is
confused about whether it's got control over Drive-1, and that bacula needs to
have it's idea of the status of that device reset.
Backups are working, but only to a single drive. The "status storage" command
produces the following:
-------------------
Device status:
Autochanger "pv132t" with devices:
"Drive-0" (/dev/tape0)
"Drive-1" (/dev/tape1)
Device "Drive-0" (/dev/tape0) is mounted with Volume="000062" Pool="Incremental"
Slot 3 is loaded in drive 0.
Total Bytes=433,027,038,315 Blocks=6,712,350 Bytes/block=64,511
Positioned at File=433 Block=851
Device "Drive-1" (/dev/tape1) is not open or does not exist.
Device is BLOCKED. User unmounted.
Drive 1 is not loaded.
-------------------
I've tried loading a new tape into drive 1 (via mtx, outside of bacula), but
any attempt to get bacula to recognize the tape (update slots, mount,
umount) seems to hang at "Contacting storage director".
Currently, there are 8 backups running, writing (slowly!) to the same drive.
Environment:
bacula-sd, bacula-dir 1.38.9 on the same server (Linux 2.4.26)
bacula-fd 1.38.9 on various servers
[1] Is there any way to force bacula to recoginize the 2nd drive without
interrupting the current backups?
[2] Will restarting bacula-sd interrupt the current backups (will they be
resumed at the same point)?
I'd appreciate any answers as quickly as possible, as there is about 4TB of
data being written very slowly, one tape at a time...when it could be using
both devices.
(By the way, I tried searching the archives on sourceforge before posting, but
that returns the message "Permission Denied. Searching of non-projects is not
allowed.")
Thanks,
Mark
