Mondo does not timeout or exit if the tape drive fails

[tastle73]

I noticed on a few occasions that when running mondorescue in verify or backup mode my tape drive will throw some kind of SCSI error. Rather than failing when it cannot read the tape, mondo runs away and takes 100% of cpu and never exits.

The command is called from a script called from cron:

mondoarchive -Vt -0 -d /dev/nst0 -o -N -e

/var/log/mondoarchive.log:

No, Schlomo, that doesn't mean /dev/mapper/vg-lv03 is the root partition. It's just a debugging message. Relax.
