I'm using AMANDA 2.4.4p3 under CentOS 4.5 on an Itanium. Previously I was using a single magazine with 11 tapes--there were no problems. After loading a second magazine and adjusting the config to use 23 tapes instead of 11 (the initial magazine has a cleaner tape), amcheck Daily fails because mtx -f /dev/sg3 status needs more time.
I've adjusted some delays in changer.conf, but it's not clear which is the crucial delay o use, and the delays seems to need to be very long (at least 45 seconds). -bash-3.00$ amcheck Daily Amanda Tape Server Host Check ----------------------------- Holding disk /var/lib/amanda/holdingdisk: 61421084 KB disk space available, that's plenty amcheck-server: slot 4: date 20071006 label Daily04 (active tape) amcheck-server: slot 5: date 20071007 label Daily05 (active tape) amcheck-server: slot 6: date 20071008 label Daily06 (active tape) amcheck-server: fatal slot 7: mtx: Request Sense: Long Report=yes ERROR: new tape not found in rack (expecting a new tape) NOTE: skipping tape-writable test Server check took 422.307 seconds Amanda Backup Client Hosts Check -------------------------------- Client check: 4 hosts checked in 10.038 seconds, 0 problems found (brought to you by Amanda 2.4.4p3)
