Hello !
I would like to try out jfs on my alpha (LX, 20164a) under Linux.
I checked out the latest version via CVS (actually, from beginning
of january), patched and compiled the kernel, compiled the utilities,
formated the partition but I am unable to mount it.
Inititally I was using 2.4.13-ac5, now 2.4.17 (both under Debian/woody)
but the results are the same. The harddisk contains BSD lables.
Here is what I get:
sixtyfor:~# modprobe jfs
JFS development version: $Name: $
Now attempting to mount:
sixtyfor:/local/local2/src/linux/fs/jfs# mount -t jfs /dev/sdb2 /mnt
mount: wrong fs type, bad option, bad superblock on /dev/sdb2,
or too many mounted file systems
Unfortunately I cannot fsck:
sixtyfor:/local/local2/src/linux/fs/jfs# fsck.jfs /dev/sdb2
fsck.jfs version 1.0.13, Jan 27 2002
Segmentation fault
When I try to strace mount, it also segfaults:
sixtyfor:/local/local2/src/linux/fs/jfs# strace mount -t jfs /dev/sdb2 /mnt 2>>~/jfsbug
Segmentation fault
Full strace below. Interestingly it looks for /sbin/mount.jfs which does
not exist (and I could not find any reference to it). Especially the
segmentation faults look like bugs to me.
The full strace for mount:
