Description Ilariu Raducan 2000-08-07 19:07:49 UTC
When trying to list an empty tape :
tar tf /dev/st0
the system fails to open new processes (bash shells in my case)
After some time (~3 min) tar reports an error and everything is working 
again.

Comment 1 Jeff Johnson 2000-08-08 15:44:17 UTC
This smells more like a problem with the st0 driver open than with tar, so I'm
changing the
component for suggestions on what to do.

Comment 2 Alan Cox 2000-09-23 22:43:17 UTC
Sounds like the tape drive does not support disconnect or is jumpered to not do
disconnect.
Is the disk on the same scsi bus ?


Comment 3 Ilariu Raducan 2000-09-24 00:16:55 UTC
Yes, it is.
The system is a Dell PowerEdge1300. Lines from dmesg:
