Subject: Linux-2.4.18-rc3-ac3: bug with using whole disks as filesystems
Date: Thu, 25 Jul 2002 18:58:12 +1000 [thread overview]
Message-ID: <004901c233b9$680612b0$638317d2@pacific.net.au> (raw)
I attempted to mkfs and use a whole disk rather than a partition
with reiserfs. It failed (not a major problem, I'll just make a
partition), but it failed with a "kernel BUG" message, so here 'tis.
A subsequent attempt to cfdisk the same disk hung and refused
to die even with a kill -9.
Here's the hung cfdisk (fdisk could touch the disk while this
is hung).
root@praxis8:~# ps lx | grep cfdisk
100 0 469 312 15 0 1852 692 rwsem_ D pts/0 0:00
cfdisk /dev/sdb
100 0 513 476 16 0 1336 428 pipe_w S pts/1 0:00
grep cfdisk
After reboot everything worked fine.
Original commands to cause failure:
mkfs -b 8192 /dev/sdb -f
mount /dev/sdb /cache
/dev/sdb is an IBM ServeRAID array, of 4x36Gb/2=72Gb.
