PMAZB-AA and ST12400N Drives

In one of my 3000-500 machines running DU 3.2c, I've just put
in a PMAZB-AA SCSI controller connected to a BA350 Storageworks
cabinet with 6 disks drives. The system sees the drives, the
kernel has been rebuilt, etc. etc.

Problems crop up when trying to use a UFS filesystem on some
of the drives. I've got one DEC RZ28 drive, and five Seagate
ST14200N 2Gig drives. The DEC RZ28 works, the ST12400N's do
not. Here's what I am doing on all of the drives :

# disklabel -rw rz21 rz28
# newfs /dev/rrz21c rz28
# mount /dev/rz21c /mnt

When I try to write a file to any of the ST12400N filesystems,
I get this :

# touch /mnt/test

/mnt: create/symlink failed, no inodes free
touch: /mnt/test cannot create

Yet, there are a boatload of inodes on this newly created
and quite empty filesystem. Any idea how to correct this?
I've tried using a custom disklabel rather than defaulting
everything to rz28 values and got the same result. The
firmware in the PMAZB-AA is V2.0, I upgraded that as well.

I'm rather stumped.. does this mean the PMAZB-AA will only
work with DEC drives?
