Help with tar: Cannot open /dev/st0: Read-only file system

I can't seem to figure out this problem for the life of me...


tar: Cannot open /dev/st0: Read-only file system
tar: Error is not recoverable: exiting now

Devices are read/writeable


crw-rw----   1 root     disk       9, 128 May  5 16:32 nst0
crw-rw----   1 root     disk       9,   0 May  5 16:32 st0

SCSI is comipiled into kernel.

Why does the system think that /dev/st0 and /dev/nst0 are read-only
filesystems?

Thanks in advance!

If it was not the case, the streamer was not detected
("no such device ...").

The are not only read-only. Lambda user cannot use the
streamer (---). 2 solutions: you put users allowed to
use the streamer in the group disk or you do a "chmod 0666".

I tried chmod to 0666 and had the same exact problem.  FYI - The tape is
not write protected.

:Devices are read/writeable

What type of drive and what kind of tape?  Many tape drives will read
from more kinds of tape than they will accept for writing, and the usual
behavior is to pretend that tapes they don't like are write-protected.

1. tar: /dev/st0: Warning: Cannot seek: Illegal seek

Hi group,

after upgrading several packages with apt I have problems backing up data to
tape (DDS-3) with the "verify" option of tar (tar cvfW). After writing the
data, at the point where tar should rewind the tape and start the verify
pass, I get the message above.

Could it be the tape media that causes this error? Unfortunately, I have no
other media for testing. What can I do to get things verified?

Thanks a lot,
Magnus
