Subject: Devfs strangeness in 2.4.18
Date: Thu, 06 Jun 2002 23:57:27 +0300 [thread overview]
Message-ID: <20020606205727.18760.qmail@dag.newtech.fi> (raw)
Hi,
just installed a fresh Mandrake 8.2 here and am
seeing devfs behaving very strangely.
Here is some out put that shows the problems:
backup:dev 1004 % ls -ld sg*
drwxr-xr-x 1 root root 0 Jun 7 2002 sg
lr-xr-xr-x 1 root root 36 Jun 7 2002 sg0 ->
scsi/host0/bus0/target0/lun0/generic
lr-xr-xr-x 1 root root 36 Jun 7 2002 sg1 ->
scsi/host1/bus0/target1/lun0/generic
lr-xr-xr-x 1 root root 36 Jun 7 2002 sg2 ->
scsi/host1/bus0/target2/lun0/generic
lr-xr-xr-x 1 root root 36 Jun 7 2002 sg3 ->
scsi/host1/bus0/target3/lun0/generic
lr-xr-xr-x 1 root root 36 Jun 6 23:46 sg4 ->
scsi/host2/bus0/target2/lun0/generic
backup:dev 1005 % cat /proc/scsi/scsi
Attached devices:

backup:dev 1006 % ls -l /dev/st?
lr-xr-xr-x 1 root root 31 Jun 7 2002 /dev/st0 ->
scsi/host1/bus0/target2/lun0/mt
lr-xr-xr-x 1 root root 31 Jun 7 2002 /dev/st1 ->
scsi/host1/bus0/target3/lun0/mt
The problems are tha the sg? links doesn't correspond to the real
devices shown by /proc/scsi/scsi (Which matches the real situation)
sg0 matches the first disk, OK
sg1 matches the Medium changer, OK
sg2 matches nothing...... There is no target 2 on host1 !!!
sg3 matches the DLT tape drive
sg4 matches the DAT tape drive
The other problem is the st? links.
st0 is linked out into nothing ...
Seems like 3 host adapters is too much for devfs......
Do I need an upgrade ?
