On a related note to the conversation below - What's the impact to increasing maxdirsize on a given volume?  We have a qtree approaching the limit for its volume.  Does maxdirsize function like maxfiles/inodes?

Re: running out of inodes problem





Just add more with maxfiles, and ask about netapps plan to adopt
dynamic inode allocation.  Which there may not be, but one can hope.
:)  We have a data set that constantly runs out of inodes, we just
keep a close eye on it, and add more inodes when needed.  We've not
had an issue with mysterious loss of performance when adding inodes
using maxfiles.

hope that helps,
