We have two aging Netapp filers and can't afford to buy new Netapp gear,

discussion
- Adding new disks to a RAID-Z pool (Netapps handle adding new disks very
nicely). Mirroring is an alternative, but when you're on a tight budget
losing N/2 disk capacity is painful.
- The default scheme of one filesystem per user runs into problems with
linux NFS clients; on one linux system, with 1300 logins, we already have
to do symlinks with amd because linux systems can't mount more than about
255 filesystems at once. We can of course just have one filesystem
exported, and make /home/student a subdirectory of that, but then we run
into problems with quotas -- and on an undergraduate fileserver, quotas
aren't optional!
well, if the mount limitation is imposed by the linux kernel you might
consider trying running linux in zone on solaris (via BrandZ). Since
BrandZ allows you to execute linux programs on a solaris kernel you
shoudn't have a problem with limits imposed by the linux kernel.
brandz currently ships in an solaris express (or solaris express
community release) build snv_49 or later.
Another alternative is to pick an OpenSolaris based distribution that
"looks and feels" more like Linux. Nexenta might do that for you.
