It's a 12/24 GB tape, so I'm thinking I put "dump -0u -B 12582912 -b 64 /dev/nrsa0 /" but that won't write to 24 GB which the tape drive is capable of with compression. Is there any way to enable that? 5) Finally, last night i was trying out flexbackup (the perl front end for dump/cpio/etc) and the tape drive froze (something about "This tape doesn't have an index at /usr/bin/flexbackup line 2385".) and sat there for over an hour not doing anything. So I killed the process and tried to kill the "mt -f /dev/nrsa0 erase" but it wouldn't, and any attempts to read/write/mount etc came back with a device busy. I eventually just restarted the box, but is there any way to stop this? Thanks for all your help.
