[comp.unix.ultrix] inode limit in file systems

jwp@larry.sal.wisc.edu (Jeffrey W Percival) (02/04/90)

I learned from responses to a previous posting that my news partition
had too few inodes.  I was maxing out on inodes before the partition
was full.  Sooo, I tried making a new file system.  It turns out, in
Ultrix 3.0, that mkfs(8) will not go below 2048 bytes/inode.  (Recall
that the number of inodes is specified in Ultrix as the number of data
bytes per inode, so smaller numbers means more inodes).  If I say 4096
bytes per inode, I get, say, 10000.  If I say 2048 bytes per inode, I
get 12288.  If I say 1024 bytes per inode, I *still* get 12288.

Am I stuck with this?  It's about a 40Mbyte partition.

There was some fairly extensive discussion about this a couple of months
ago.  If nobody pulls out the right answers, I'll grep it out and post
something tonite...
