Yesterday I did a test run using Amanda 2.5.0 - just backing up a single DLE, and all seemed well. So last night I ran my first test to see how Amanda 2.5.0 handles spanning across multiple tapes. This morning, tape daily-3 was ejected, amstatus looked OK, and I inserted the next tape (daily-4). However, the tape drive thinks about it for a while and then spits out the tape. I thought it may be the tape itself, so tried daily-5 eventually, but with the same result (I'm pretty sure the tapes are good).
I'm using a single-slot HP StorageWorks SDLT320 tape drive, so I have a feeling that somewhere there's a problem with using it as if it has multiple slots. In amanda.conf, I've got the following entries - the rest are pretty much standard: runtapes 2 tpchanger "chg-manual" tapedev "/dev/nst0" changerfile "/etc/amanda/daily/changer.conf" changerdev "/dev/null" chunksize 1Gb tape_splitsize 1Gb In /etc/amanda/daily: changer.conf is an empty file, created manually (by me) changer.conf-access contains a value of 9 changer.conf-clean contains a value of 9 changer.conf-slot contains a value of 8 I've had a look a the logs, but don't know what the make of them: amindexd.20080529170749.debug shows no errors. amcheck.20080529172331.debug contains the following, and succeeds: changer: got exit: 0 str: 2 99 1 changer_query: changer return was 99 1 changer_query: searchable = 0 changer_find: looking for NULL changer is searchable = 0 changer: got exit: 0 str: 2 /dev/nst0 changer.debug contains: >>> First attempt to insert next tape (daily-4) /dev/nst0 status: ONLINE BOT -> loaded </dev/nst0 status: ONLINE BOT> AMANDA: TAPESTART DATE X TAPE daily-4 014 1+0 in 1+0 out Exit -> 3 /dev/nst0 MT -> /usr/sbin/ammt -f DD -> /usr/sbin/amdd Args -> -slot next -> rewind /dev/nst0 -> status /dev/nst0 /dev/nst0 status: ONLINE BOT -> loaded </dev/nst0 status: ONLINE BOT> -> offline /dev/nst0 -> load 4 -> rewind /dev/nst0 /dev/nst0 rewind failed: Input/output error -> status /dev/nst0 /dev/nst0 status failed: Input/output error -> loaded <> -> rewind /dev/nst0 /dev/nst0 rewind failed: Input/output error -> status /dev/nst0 >>> Second attempt to insert next tape (daily-4) /dev/nst0 status: ONLINE BOT -> loaded </dev/nst0 status: ONLINE BOT> AMANDA: TAPESTART DATE X TAPE daily-4 014 1+0 in 1+0 out Exit -> 4 /dev/nst0 MT -> /usr/sbin/ammt -f DD -> /usr/sbin/amdd Args -> -slot next -> rewind /dev/nst0 -> status /dev/nst0 /dev/nst0 status: ONLINE BOT -> loaded </dev/nst0 status: ONLINE BOT> -> offline /dev/nst0 -> load 5 -> rewind /dev/nst0 Would appreciate any advice. I've read through http://wiki.zmanda.com/index.php/Amanda.conf and http://wiki.zmanda.com/index.php/Splitting_dumps_across_tapes, but may be missing something somewhere. Thanks, as always.
