We recently purchased a swallow5 disk for our Sequent system.  When
moving my users partition from a 256 MB swallow to the new swallow I
came across the problem of running out of inodes.  It seems that mkfs
limits the number of inodes per cylinder group to 2048.  The new
swallow has cylinders that are about 4 times as dense as the old
swallow.  Mkfs also limits the number of cylinders per group to at
least 16.

Does anyone know the effect of changing the code to allow fewer than
16 cylinders per group or more than 2048 inodes per cylinder group?
Or does anyone have a suggestion as to how to get more inodes on a
partition.

We have also recently added a swallow 5 to our sequent configuration. The work
we are using the new disk for is somewhat indoe hungry (lots of symlinks) so
I made the filesystem using:

	mkfs -b 4096 -f 512 -c 4 -i 2048 zd8c zdswallow5

and ended up with a better inode <-> disk block ratio than on the standard
swallow. I guess -c 6 will be more what you are looking for though.
