Was trying to do an 'amrestore /dev/nst0' when I received the following OOPS:


I've also had problems restoring large XFS partitions off of tape
(amrestore returns with input/output errors), but I'm not sure whether
that is kernel or userspace related (no errors in dmesg or anything).
In that case, amrestore did not have any problems restoring TAR-ed
filesystems from tape (that was with 2.6.14-gentoo-r5).


As a follow-up to the above on 2.6.14-gentoo-r5, while trying to
restore an XFS partition off of the tape (amrestore/dd doesn't oops on
this kernel) my dmesg fills with the following:

st0: Error with sense data: <6>st0: Current: sense key=0xb
ASC=0x4b ASCQ=0x0

the command I'm running specifically is:
dd bs=32k skip=1 count=520531 conv=noerror,notrunc if=/dev/nst0 of=fs0restore

As you can see, my backups are not going as well as I had planned.

Thanks again.
