Hi,
I just installed OpenSolaris on my Dell Optiplex 755 and created
raidz2 with a few slices on a single disk. I was expecting a good
read/write performance but I got the speed of 12-15MBps.
How can I enhance the read/write performance of my raid?
Thanks,
Abhi.
You absolutely DON'T want to do what you've done. Creating a ZFS pool
(or, for that matter, any RAID device,whether hardware or software) out
of slices/partitions of a single disk is a recipe for horrible performance.
In essence, you reduce your performance to 1/N (or worse) of the whole
disk, where N is the number of slices you created.
So, create your zpool using disks or partitions from different disks.
It's OK to have more than one partition on a disk - just use them in
different pools for reasonable performance.
