When I create a disklabel and newfs the filesystem more than a few gigs on
either one of my Ultra1 sparc64 boxes, I can't mount them (mount_ffs:
invalid parameter) until I run an fsck and fix the superblock.
Here's an example:
# disklabel -E sd0
This platform requires that partition offsets/sizes be on cylinder
boundaries.
Partition offsets/sizes will be rounded to the nearest cylinder
automatically.

BAD SUPER BLOCK: MAGIC NUMBER WRONG
LOOK FOR ALTERNATE SUPERBLOCKS? [Fyn?] y
USING ALTERNATE SUPERBLOCK AT 32
** File system is already clean
** Last Mounted on
** Phase 1 - Check Blocks and Sizes
** Phase 2 - Check Pathnames
** Phase 3 - Check Connectivity
** Phase 4 - Check Reference Counts
** Phase 5 - Check Cyl groups

UPDATE STANDARD SUPERBLOCK? [Fyn?] y
***** FILE SYSTEM WAS MODIFIED *****

I've run this on a vanilla 4.1 install, as well as a stable kernel/userland
upgraded as of last night.
Any clues?
