UFS on System V uses the System V partition table, which allows 15 partitions. I don't know what use even 7 are, which is probably one of the reasons nobody has done anything about it. >> I'm also intersted in having a way to shrink an FFS filesystem, but it is >> much more difficult than growing and you have to rename inodes which is not >> always good. >> At this moment I'm thinking of some ways to retain the inode numbers. >> In the more common case your system is getting to small and you want to >> have another HDD added - so only be able to grow does make sense. > > For me the issue has always been a mistake in the allocation of space on > my disks.

I'm not sure what you're talking about here, but the best thing I can think of is Vinum.
