I've got this 1.3 Gig SCSI drive that's about to go out. It has to warm
up for about 30 minutes when starting cold (not kidding) and for the
most part runs fine until a storm comes along and causes the power to
drop. (Yes, I know, a new drive and/or a UPS would fix this). However,
every now and then, it produces a read error and I get this panic:
SCSI disk error : host 0 channel 0 id 0 lun 0 return code = 28000002
Current error sd08:02: sns = f0 4
ASC=15 ASCQ= 1
Raw sense data:0xf0 0x00 0x04 0x00 0x22 0xef 0x75 0x28 0x00 0x00 0x00
0x00 0x15 0x01 0x00 0x80
scsidisk I/O error: dev 08:02, sector 1245228
Kernel panic: EXT2-fs panic (device 08:02): ext2_read_inode: unable to
read i-node block - inode=155765, block=622614
This is a Fujitsu M2651SA on an Adaptec 2940 controller. Kernel is
2.0.21 (although the behaviour has been the same for quite some time,
now). System is a P/100, 48 meg RAM.
Does the SCSI driver retry after an error? When I get an error access a
dos partition on the same drive from within dos, I usually don't get the
error a second time.
After this happens, I can't shut down clean, not even my other drives.
It becomes a permanent error and I have to hit reset to recover my
system. Sync locks up, init fails to init, reboot just prints it's
message and does nothing else. Surely this doesn't have to have such
catastrophic effects.
Any advice on how to clean up the error without having to reboot?
Thanks,
Robert
