I too am having the same issues. I started out using Solaris 10 8/07 release. I could create all the filesystems, 47,000 filesystems, but if you needed to reboot, patch, shutdown.... Very bad. So then I read about sharemgr and how it was supposed to mitigate these issues. Well, after running a process that creates zfs filesystems for all our users and then they get shared through inherited zfs/nfs permissions I have only 6400 filesystems created after 3 days of the process running. Not very good. I am going to try and recreate the filesystems with sharenfs being done on each filesystem rather than from the top of the tree to see if I can improve the speed. In case you are wondering the system I have configured is the following.
Sun v245 with 16 gigs of RAM and 2 procs 3 Apple X-Raids in a RAID-Z config -- each X-Raid is really like 2 direct attached... so there are 6 independent connections to the server. More like a RAID-Z set with 6 disks attached. You may ask why I would have that many filesystems. Well, as one of the posters above pointed out, we had this same setup on an aging sun 450 server. We had the 47k user home directories stored on it with quotas enabled. Well, we needed to migrate this to a new system and ZFS seemed like it was the answer to all our problems. We have 16TB raw disk and needed a filesystem that could see this, was robust, and very safe/secure. Enter zfs...maybe. Well, I can see all the disk, I can create all the directories, I have done some load testing....Impressive. I just can't share them.
