Hello List, I am using Bacula 3.0.3 in conjunction with a 4 drive autochanger and "Prefer Mounted Volumes" set to "No." Unfortunately, I have had a number of problems with Bacula trying to back up to a volume that is already being used for another job. As a result, the job will continue to wait for the tape in the other drive to become free, essentially eliminating any benefit that the job concurrency might have had.
This problem is occurring on a nightly basis, with some nights being worse than others. If I tell Bacula to prefer mounted volumes instead, the backups complete just fine, but then I am not taking advantage of the large tape library that we have at our disposal. Here is an example of what I see in the logs. This will repeat until the tape is finally freed from the other drive (which can sometimes be hours). backup.domain.tld-dir JobId 4783: Start Backup JobId 4783, Job=jobname.2010-02-24_02.00.00_11 backup.domain.tld-dir JobId 4783: Using Device "Drive-5" backup.domain.tld-sd JobId 4783: 3301 Issuing autochanger "loaded? drive 5" command. backup.domain.tld-sd JobId 4783: 3302 Autochanger "loaded? drive 5", result: nothing loaded. backup.domain.tld-sd JobId 4783: Warning: Volume "023071" wanted on "Drive-5" (/dev/nst3) is in use by device "Drive-4" (/dev/nst2) backup.domain.tld-sd JobId 4783: 3301 Issuing autochanger "loaded? drive 5" command. backup.domain.tld-sd JobId 4783: 3302 Autochanger "loaded? drive 5", result: nothing loaded. backup.domain.tld-sd JobId 4783: Warning: Volume "023071" wanted on "Drive-5" (/dev/nst3) is in use by device "Drive-4" (/dev/nst2) backup.domain.tld-sd JobId 4783: 3301 Issuing autochanger "loaded? drive 5" command. backup.domain.tld-sd JobId 4783: 3302 Autochanger "loaded? drive 5", result: nothing loaded. backup.domain.tld-sd JobId 4783: 3301 Issuing autochanger "loaded? drive 5" command. backup.domain.tld-sd JobId 4783: 3302 Autochanger "loaded? drive 5", result: nothing loaded. backup.domain.tld-sd JobId 4783: Warning: mount.c:227 Open device "Drive-5" (/dev/nst3) Volume "023071" failed: ERR=dev.c:491 Unable to open device "Drive-5" (/dev/nst3): ERR=No medium found Any help would be greatly appreciated. -- Dave ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
