Subject: corrupted UFS2 label after ffs_vfsops.c,v 1.198
Hi,
after cvsupping a kernel with the mentioned version of ffs_vfsops.c
I tried to upgrade my kernel from a some weeks aged -current.
After that I'm no longer able to mount or fsck a UFS2 formatted
disk. My dmesg is attached.
Trying fsck_ffs /dev/da0s1a gives:
(nihil)(root) # fsck_ffs /dev/da0s1a
** /dev/da0s1a
Cannot find file system superblock
LOOK FOR ALTERNATE SUPERBLOCKS? [yn] y
Fließkommafehler
(floating point error in german)
Any possible alternate superblock given with -b gives
a fp-error also.
How to resolve this?
Bye!

Once you have upgraded your fsck to the current version, it will only
check converted UFS2 filesystems. To convert your UFS2 filesystem,
simply mount it with your new kernel. Once you have done that, you
will be able to unmount it and run the new fsck. Similarly, if you
have an older kernel (vintage last four months of -current) then it
will back-convert your UFS2 filesystems every time you run it and thus
you will have to forward convert before fsck will run on it again.
