Hi all,
More a discussion question than an urgent cry for help ( mind you... :o) )
We use AIT-2 tape drives for backup on some servers here and recently
either the device or the media failed on one of them during a write
process (tar).
This failure left the device ( /dev/tape ) in a state of busy. There was
little I could find that I could do except reboot the machine to get it
to free up the tape drive. There were (according to ps -eaf and fuser )
no processes and/or tasks using that device so I had nothing I could
kill to free up the supposedly busy tape.
In this instance, rebooting was not a major headache but wondering what
I would have done if it was preferable not to reboot. Anyone have any
alternatives to rebooting in order to free a busy device/tape drive?
cheers
