I've got a Neo8000 and it spends 10 seconds at most before moving, when given a load/unload command. 2 minutes sounds manifestly excessive - I'd guess that something else on the machine is holding the sg device open. > However, mtx, Bacula and the library itself have quite different > opinions on which way to number the slots. No big deal mostly but for > the 'mail magazine'. I have not yet further investigated this. The library can be configured to make slots and drives 0-anchored or 1-anchored. The defaults usually match mtx. Which is chosen doesn't matter as long as bacula and the library agree on which slot number any given tape is in - bacula believes mtx for this and if mtx is used for all activity then any disagreement is moot. (FWIW MTX is 0-anchored for drives and 1-anchored for slots) Assuming 1-anchoring on slots, the mail magazine is slots 501-515 I've written a couple of simple shell scripts to load/unload the magazine (places tapes randomly in slots to give even wear patterns) Update slots MUST be run after any changes or things start getting out of sync very quickly. Because of potential multipathing issues and varying discovery order at startup, it's best to NOT refer to drives as /dev/nst* in bacula's configuration, but to use /dev/tape/by-id/ Even better is to create something like /etc/bacula/DEVICES/ and put symlinks from /dev/tape/by-id/XYZ to changer-driveN in there, then use those inside bacula - that makes the setup much more human readable. ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
