[Bacula-users] automatic (un)mount of USB disk does not work
Hi,
I'm trying to get a USB disk to be automatically mounted and unmounted
before/after each backup job with Bacula 1.38.9. My USB drive in at /dev/sdb,
so I created this device configuration for the Storage Daemon:
Device {
Name = FileStorage
Media Type = File
Archive Device = /dev/sdb1;
LabelMedia = yes;
Random Access = Yes;
Automatic Mount = yes;
Removable Media = yes;
Always Open = no;
Label Media = yes;
Requires Mount = yes;
Mount Point = /media/sdb1;
Mount Command = "/bin/mount -t ext3 -o rw %a %m"
Unmount Command = "/bin/umount %m"
}
With this setup, bacula-sd complains:
dev.c:189 Write part command must be defined for a device which requires
mount.
So, I addedd this "Write Part Command" line:
Write Part Command = "echo nothing > /dev/null"
Unfortunately, the backup jobs don't run as expected. Bacula keeps waiting for
the volume to be mounted. If I run bacula-sd with debugging turned on, I get
the following output:
server-sd: dev.c:276 open dev: tape=0 dev_name="FileStorage" (/dev/sdb1)
vol=FILE0004 mode=OPEN_READ_WRITE
server-sd: dev.c:476 Enter: open_dvd_dev: DVD dev= mode=OPEN_READ_WRITE
server-sd: dev.c:493 open_dvd_device: num_parts=0, VolCatInfo.VolCatParts=0

server-sd: dvd.c:824 check_can_write_on_non_blank_dvd: got 8 files in the
mount point (matched=0)
server-sd: dvd.c:93 Enter unmount_dev
server-sd: dvd.c:93 Enter unmount_dev
After that, nothing happens and the console log says:
24-May 13:09 server-sd: Please mount Volume "FILE0004" on Storage Device
"FileStorage" (/dev/sdb1) for Job BackupCatalog.2006-05-24_13.08.55
How do I get Bacula to recognize the files on the disk properly?
Best regards,
Henning Holtschneider

How do I do this? I'm a bit confused because the documentation does not seem to be up to the code and it mainly refers to DVDs, which have to be treated differently than removable hard drives. I know that I can use fstab-sync to automatically mount any partition on a hot-plug device to a unique mount point, but how does this integrate with Bacula?

I suppose you are referring to [1] http://article.gmane.org/gmane.comp.sysutils.backup.bacula.general/22626 and [2] http://article.gmane.org/gmane.comp.sysutils.backup.bacula.general/22598 While these approaches are nice, there are two serious problems which render them useless in many environments: [1] requires the disk to be unmounted manually. In many cases, there is no qualified personnel available to unmount the backup disk before actually unplugging the disk. Usually, this would not destroy any data on the disk but this is no clean solution for unattended operation. [2] shows nice disk handling, but it still requires a temporary spool directory where Bacula stores the backup data before actually writing it to the disk. Considering the amount of wasted space, this is ridiculous. I don't understand while Bacula treats all removable non-tape media as DVDs, which requires spooled write access. If only the storage director would support the options "Mount Command" and "Unmount Command" without the "Write Part" command (... and underlying logic), most problems related to backing up to removable disks would be solved. However, I faced almost the same problem about two years ago and I had to abandon Bacula back then because backing up to removable disks was more or less impossible. Bacula has made huge improvements since then and I hope it doesn't take two more years to fill in the remaining holes in the implementation ;-) Best regards, Henning Holtschneider -- LocaNet oHG - http://www.loca.net Lindemannstrasse 81, D-44137 Dortmund tel +49 231 91596-25, fax +49 231 91596-55 sip [EMAIL PROTECTED] pgpjkaqSQ35ki.pgp Description: PGP signature
[Bacula-users] problems with incremental backups after upgrade
Hi, I upgraded our Bacula server from 1.36.3 to 1.38.11. Since then, I cannot run incremental backup jobs on some (!) clients anymore. All I get is this: 24-Jul 00:00 weissnich-dir: Start Backup JobId 1762, Job=webfarm3.2006-07-23_23.50.04 24-Jul 00:00 weissnich-dir: webfarm3.2006-07-23_23.50.04 Error: bnet.c:257 Read error from File daemon:webfarm3.dortmund.loca.net:9102: ERR=Connection reset by peer 24-Jul 00:00 weissnich-dir: webfarm3.2006-07-23_23.50.04 Error: Bacula 1.38.11 If I run a full backup of the same client, everything is fine. I upgraded the existing Bacula database with the supplied script and modified the filesets in bacula-dir.conf. Everything else has been left untouched except for one client which I also upgraded from 1.36.6 to 1.38.11. It shows the same symptoms as the other (older) clients. What can I do to track down the problem?

All I get is this: Meanwhile, I solved my problems: two clients were still running Bacula 1.34 and the third one, which I upgraded to 1.38.11, had re-started the old file daemon. After correcting these errors, everything is fine! After all, Bacula 1.38 seems to be able to back up clients down to 1.36, but not below that version. I suppose I could have RTFM that ;-) Cheers, Henning Holtschneider -- LocaNet oHG - http://www.loca.net Lindemannstrasse 81, D-44137 Dortmund tel +49 231 91596-25, fax +49 231 91596-55 sip [EMAIL PROTECTED] pgpq71rN6wQJA.pgp Description: PGP signature - Take Surveys.

That sounds good. The volume status update can be automated as a Run Before Job script, i.e. check which volumes are available and mark all other volumes as Used (or Full). But what do I set the status to when I want to re-use the volumes marked as Used or Full before? Will volstatus=Purged result in the database records being purged as soon as the volume is actually being written to or will I be left with a huge pile of orphaned database records after a while? I already experienced that it's no good idea to set volstatus=Append because this will cause Bacula to append to the volume beyond the "Maximum Volume Bytes" setting, which will in turn cause a serious deadlock of Bacula once the USB disk runs out of free space :-/ Or will the volume be purged automatically once the volume retention period has been exceeded?
