For ~100 people, I like Bob's answer. RAID 10 will get you lots of speed.
Perhaps RAID50 would be just fine for you as well and give your more space, but
without measuring, you won't be sure. Don't forget a hot spare (or two)!
Your MySQL database - will that generate a lot of IO?

To be honest, never. It's a cheap server sat at home, and I never got around
to writing a script to scrub it and report errors.

Hi,
Currently no ACL inheritance takes place when a new
file system is
created. Feel free to open an RFE for this.
Thank you for your reply ...
Good to know about it, but its really simple to write a small shell-script that
would create the home directory, change ownership and set the ACL
Just a side note on the PERC labelled cards: they don't have a JBOD
mode so you _have_ to use hardware RAID. This may or may not be an
issue in your configuration but it does mean that moving disks between
controllers is no longer possible. The only way to do a pseudo JBOD is
to create

Such entries should go away with an invocation of devfsadm -vC.
If they don't, it's a bug IMHO.

Hi,
I'd like to be able to select zfs filesystems, based on the value of properties.
Something like this:
zfs select mounted=yes
Is anyone aware if this feature might be available in the future?
If not, is there a clean way of achieving the same result?
Thanks, Mike.

How about this:

This is not a straight to disk connection and you'll have problems if
you ever need to move disks around or move them to another controller.
I agree that the MD1000 with ZFS is a rocking,

I thought the 1078 are supposed to work with SPARC (mega_sas).

Because the property compression could decrease the file size, and the
