ZFS disk strategies

[Paul Austin]

I'm looking at a fresh install of Nexenta and with be using ZFS at the
file system. What I was thinking of doing is partitioning the disk to
have a 50GB partition and a 450GB partition. This would be done on two
disk drives. I would then create a ZFS mirrored pool on the two 50GB
partitions and a regular pool on the two 450GB partitions. I would
create a ZFS file system under / from the mirrored pool. Then I can use
the non mirrored pool for other parts of the file system that I don't
need a redundant setup for.

Is this kind of scheme a good thing to do and would it be easy to setup
as part of the install?

Cheers,
Paul

Paul,

this is not a good scheme. Reason is simple - if system pool dies, you
don't want your data pool be dead as well. And mirror will not help
here.

The best you can do is isolate system pool from data pool physically.
I.e. add 2x80GB disks to the system and use them for your system pool
only.
