We are using the following equipment:
- 12 x WD RE3 1TB SATA
- 1 x lsi 1068e HBA
- supermicro expander
- xeon 5520 / 12gb memory
We're having very slow read performance on our san/nas. We have one raidz2 pool
of 12 devices. We use the pool for iscsi ( xenserver virtual machines) + cifs
share.

Hi all,
I've been following the Oracle Solaris ZFS Administration guide here:
http://download.oracle.com/docs/cd/E19963-01/821-1448/ftyxh/index.html
I am able to create my ZFS volume but am having trouble when I get to the step
of creating a LUN using sbdadm, it will inevitably return the
My first inclination is 128k is too small for a pool component.
You might try something more reasonable, like 1G, if you're
just testing.
Thanks,

Oh, and with 4x 3 TByte SATA mirrored pool is pretty much without

You can also use raidz2, which will have a little more resiliency.
With mirroring, you can lose one disk without data loss, but losing a

The discussion is really old: writing many small files on an nfs mounted zfs

Is it true that a raidz2 pool has a read capacity equal to the slowest
disk's IOPs
per second ??
No, but there's a grain of truth there.
