John, I believe this is expected, given the log entries above it.. bacula never told the autoloader to load drive 0 after unloading it. I'll step through the log entries below in order and say what I think they are telling me: 11-Aug 01:30 zztop-dir JobId 9: Using Device "chg0_drive0" 11-Aug 01:30 zztop-sd JobId 9: 3307 Issuing autochanger "unload slot 1, drive 0" command. * Okay, we want to use drive0. It has a tape in it - unload it. 11-Aug 01:33 zztop-sd JobId 9: Warning: Volume "bvol_ELAN-OnSite0_003" wanted on "chg0_drive0" (/bacula-storage/chg0/drives/drive0) is in use by device "chg0_drive2" (/bacula-storage/chg0/drives/drive2) * Hmm this is strange, the volume that we decided to use is already mounted in another drive. (likely considered a warning because logically the selection code should have picked this drive, yes?) 11-Aug 01:33 zztop-sd JobId 9: 3301 Issuing autochanger "loaded? drive 0" command. 11-Aug 01:33 zztop-sd JobId 9: 3302 Autochanger "loaded? drive 0", result: nothing loaded. * Is the drive we want to use, drive 0, loaded? Nope. (but then, I haven't asked the autoloader to load it!) 11-Aug 01:33 zztop-sd JobId 9: Warning: Volume "bvol_ELAN-OnSite0_003" not on device "chg0_drive0" (/bacula-storage/chg0/drives/drive0). 11-Aug 01:33 zztop-sd JobId 9: Marking Volume "bvol_ELAN-OnSite0_003" in Error in Catalog. * Hmm this is strange, I expected the volume to be available in drive 0 (even though I never asked for it to be loaded there) and it is not. Something msut be wrong with the volume, marking it as Error. 11-Aug 01:33 zztop-sd JobId 9: Warning: mount.c:217 Open device "chg0_drive0" (/bacula-storage/chg0/drives/drive0) Volume "bvol_ELAN-OnSite0_003" failed: ERR=dev.c:549 Could not open: /bacula-storage/chg0/drives/drive0, ERR=No such file or directory * I'm trying to open the drive anyway, just in case the autoloader is lying to me? (just guessing there).. Can't open it, because nothing is loaded in it (/bacula-storage/chg0/drives/drive0 would be a symlink to the actual volume file, if the autoloader had been told to load drive 0) When I tried to solve this before, I dug into the code and to my shallow understanding of it, it looked like the volume & device selection code had some special cases to pick drives that already had the wanted volume loaded, but that they were perhaps disabled for Disk devices... I need to get this resolved if possible so I'll start to dig in again.. I turned up the debugging and tracing on the SD and dir, and will post those as soon as I have them.. In doing another test, it seems to be much harder to replicate this if I start all 20 jobs by hand rather than have them auto-start based on schedule.. not sure if that's a concurrency thing or what Any ideas? :-/ Thanks, Joe ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
