I am using amanda 3.1.1 on a Sun Solaris 10 x86.
I have been running my daily backups with no problem but, by using taperflush=100, my daily backups only require one tape and the rest of the data is kept in the holding disk to be flushed at the next daily backup. I have just started doing my monthly archive backups, which requires that all the data be level 0 and be flushed to tape and so my taperflush=0, which means that amanda has to change tapes during the backup. Since going to amanda 3.1.1 I am getting the following error message on my archive backup, which causes my backup to go into degrade mode. hertz /gauss/export/users-m lev 0 partial taper: Error writing block: Mysterious short write on tape device: Tried 2097152, got 1052672 hertz /gauss/export/users-y lev 0 FLUSH while ejecting volume: Can't open tape device /dev/rmt/0cbn: Device busy Moving to amanda 3.1.1, I have moved to the chg-robot define changer which is defined as: tapedev "c4" define changer "c4" { tpchanger "chg-robot:/dev/changer/0" changerfile "chg-zd-mtx-state" property "tape-device" "0=tape:/dev/rmt/0cbn" property "eject-before-unload" "yes" property "eject-delay" "5" property "use-slots" "31-36" property "load-poll" "0s poll 3s until 120s" } I used the same values in the define changer above that I had in my 2.6.1p2 amanda.conf file, which had no changer problems. 1) I am thinking this might be a changer timing problem. Does this sound correct or am I way off base? 2) Should the value of "eject-before-unload" equal "yes" or "true" or will either work? I am thinking of modifying the define changer to add a little more time. tapedev "c4" define changer "c4" { tpchanger "chg-robot:/dev/changer/0" changerfile "chg-zd-mtx-state" property "tape-device" "0=tape:/dev/rmt/0cbn" property "eject-before-unload" "yes" property "eject-delay" "10" <<<<<< property "unload-delay" "10" <<<<<< property "use-slots" "31-36" property "load-poll" "0s poll 5s until 120s" <<<<< } 3) Any other suggestions. 4) I looked through the /tmp/amanda logs and the /var/amanda/archive logs but could not find any useful information about this error. This does not mean that it is not their it means that there is some much information that I cannot find what I am looking for. What log file would give me more information about the above error, so I can narrow down the log file that I need to search.
