One additional possibility, the external USB drive. My pair shut off the drive motors when unused. On next access attempt the attempted read hangs while the drive wakes up. I can see amcheck might abort this read due to some timeout. One possible way to avoid this is to combine the call to amcheck with a preceeding action that accesses the drive so it is already awake when amcheck is called. Maybe an 'ls' of a directory on the drive. > > From: "Amanda user" <[email protected]> > Date: Feb 4, 2013 4:43 PM > Subject: 60 Village Drive AMANDA PROBLEM: FIX BEFORE RUN, IF POSSIBLE > To: <[email protected]> > Cc: > > Amanda Tape Server Host Check > ----------------------------- > Holding disk /dumps/amanda: 98976 MB disk space available, using 98876 MB > slot 25: volume '60villagedrive-025' is still active and cannot be overwritten > slot 26: volume '60villagedrive-026' > Will write to volume '60villagedrive-026' in slot 26. > NOTE: skipping tape-writable test > Server check took 2624.707 seconds > > Amanda Backup Client Hosts Check > -------------------------------- > WARNING: bach: selfcheck request failed: timeout waiting for REP > Client check: 3 hosts checked in 95.344 seconds. 1 problem found. > > (brought to you by Amanda 3.2.0) > > The second issue is what Amanda is stating about the tape(s) it is > expecting in the amdump report: > > "These dumps were to tape 60villagedrive-027. > The next tape Amanda expects to use is: 60villagedrive-vault-023. > The next new tape already labelled is: 60villagedrive-028." > > The 'vault' tapes are on a *different* virtual changer (full backups > are vaulted there weekly and these vault tapes are burned to DVD-Rs from > time to time).
