Hi.
Only indirectly related to zfs. I need to test diskusage/performance
on zfs shared via nfs. I have installed nevada b64a. Historically
uid/gid for user www has been 16/16 but when I try to add uid/gid www
via smc with the value 16 I'm not allowed to do so.

Hmm, I don't know how you figure this has nothing to do with zfs. This is all
about zfs and seems to me zfs-discuss is the perfect thread for it.
Because the discussion tu
Perhaps Jonathan Schwartz really didn't want ZFS in OS X - Solaris competition
- and he knew that if he did pre-announce ZFS in OS X that Steve Jobs would
drop it just to get back at him. Maybe this was intentionally done by Schwartz
to keep ZFS out of a competing OS. Just a thought.

Hi.
I'm managing a HDS storage system which is slightly larger than 100 TB
and we have used approx. 3/4. We use vxfs. The storage system is

shared via nfs to our webservers.
If I was to replace vxfs with zfs I could utilize raidz

Hi.
If I create a zpool with the following command:
zpool create tank raidz2 da0 da1 da2 da3 da4 da5 da6 da7
and after a reboot the device names for some reason are changed so da2
and da5 are swapped, either by altering the LUN setting on the storage
or by switching cables/swapping disks etc.?
Over the weekend I got ZFS up and running under FreeBSD and have
had much the same experience with it that I have with Solaris - it works
great out of the box and once configured, it is easy to forget about.
So far the only real difference is anything you might tune via /etc/system

I have tested zfs for a while and is very impressed with the ease one
can create filesystems (tanks). I'm about to try it out on a atabeast

this goes well (as I assume it will) I'll consider to desploy zfs on a
larger scale
