Hi, IHAC who wants to use ZFS for user''s home directory. He is worry about the number of mount points. Does ZFS have any limitation about the number of mount points in a server? Regards, Jono

I saw Solaris 2.6 (yes 2.6) systems with 10,000 local mount points most of which were shared via NFS. -- Darren J Moffat

There''s another CR which I can''t find right now, but it has to do with ZFS trying to mount everything at boot time, resulting in a long-ish boot. Not a big deal if number of FS is small, but if it''s in the tens of thousands probably something to think about. -CT
Bud ig 6538014 ( http://bugs.opensolaris.org/view_bug.do?bug_id=6538014 ) was also related to mounting many fs. but I have no visibility on this bugID progress..maybe someone from Sun can update us? selim ------------------------------------------------------ Blog: http://fakoli.blogspot.com/ On 11/2/07, Christine Tran <Christine.Tran at sun.com> wrote:> Hidehiko Jono wrote: > > Hi, > > > > IHAC who wants to use ZFS for user''s home directory. > > He is worry about the number of mount points. > > Does ZFS have any limitation about the number of mount points in a server? > > > > No limit as far as I know, but you may want to check out CR 6425094; > that one has to do with mem requirement.
