ran 'top', looked at 'mem free' created 1000 filesystems ran 'top' again. rebooted to be sure ran 'top' again I'm sure I should use something better than top, but it does the job. I just repeated this and found that I was wrong on usage. 1000 filesystems brought my free memory on a freshly booted system down from 856MB to 620MB. I make 236KB per filesystem. If that's right, 10,000 mounts would eat 2.4GB of memory. > > The ability to mount a tree of ZFS filesystems in > > one go would be useful. > I'm not sure but IIRC there were changes to NFS v4 to > allow it - but you should check (search opensolaris newsgroups). It looks like it's a proposed feature in NFSv4, but it only seems to run on the 'powerpoint' platform so far... > You can start with one filesystem and migrate account > by account later.

What happens if the contents of the dir before conversion will not fit into the quota that you set on the directory? I'm sure there's other problems too. It's easier to leave things like filesystem conversion to standard utils than have tools like zfs taking magical actions in the background. Steve.
