oops, you got me! Guess I didn't RTFM close enough ;)
However, this morning I came in and the same error happened last night
when Amanda ran (using /dev/nsa0). When I tried to flush it to tape (on a
fairly new tape, only used 17 times), it failed again. I even ran the
tape cleaner. Only putting in a brand new tape did it work. Is the sa
driver that particular about used tapes?!!
Note to developers, there's a discrepency in the documentation for
sa(4) and mt(1) for the proper SCSI tape devices.
from mt(1):
FILES
/dev/*rwt* QIC-02/QIC-36 magnetic tape interface
/dev/*rsa[0-9]* SCSI magnetic tape interface
from sa(4):
FILES
/dev/[n][e]sa[0-9] general form:
/dev/sa0 Rewind on close
/dev/nsa0 No rewind on close
/dev/esa0 Eject on close (if capable)
/dev/sa0.ctl Control mode device (to examine state while another
program is accessing the device, e.g.).
I think I saw it was mentioned that the /dev/r* device was only there for
historical reasons and was probably going away -- but don't quote me on that ;)
