The nfs inode cache is quite large > (from slabtop): Hmmm... Can you get me a dump of /proc/fs/fscache/stats to look at? The "Objects:" and "Relinqs:" lines are the most interesting. On the first line avl=N shows the number of objects that are in the "available" state - ie. are live for caching. Also, can you do: df -i /path/to/cache/partition to get the number of inodes available and used. David
