Public bug reported: Binary package hint: amanda-server
I have a server with Ubuntu Feisty Server, and is about to add a backup service to it as well. However, when I run: su backup -c "amlabel DailySet1 DailySet1-0" I get: rewinding, reading label, not an amanda tape (Device or resource busy) rewinding, writing label DailySet1-0, checking label amlabel: not an amanda tape (Device or resource busy) After some research, I found out that this behavior is the same with HP StorageWorks DAT72 USB (internal) from http://forums.zmanda.com/showthread.php?t=462 The fix to this is to recompile amanda with --with-maxtapeblocksize=64k. I tried with dd, and apparently a blocksize between 32k and 124k works. Blocksize of 31k gives "dd: reading `/dev/st0': Cannot allocate memory" and 125k gives "dd: reading `/dev/st0': Device or resource busy". Maybe it could be a problem with the cciss driver as well, all I've done so far is: echo "engage scsi" > /proc/driver/cciss/cciss0 This to get SCSI on the controller. Maybe a blocksize can be increased for the controller or tapedrive? I don't like recompiling stuff from source on my servers (and the hassle of getting a good build environment on my pretty binary installations just feels bad - I left Gentoo for a reason) and there must be a good reason why amanda is compiled with --with-maxtapeblocksize=256k in the deb, so I'd rather raise the throughoutput on the controller or tapedrive before recompiling the software. However, I haven't found any information on raising these bars - will this be solved upstream (either by making maxblocksize a configuration option or decreasing maxblocksize in the deb) or am I forced to recompile amanda for myself? ** Affects: amanda (Ubuntu) Importance: Undecided Status: New -- amanda maxblocksize too high for HP Ultrium 1-SCSI drive https://bugs.launchpad.net/bugs/136456 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
