Hello
I have one 80gb hdd and 2 identical 320 hdd-s. All of them are sata drives.
I'm going to install OpenSolaris 2009.06 on 80gb HDD and create
mirrored pool using 2 320 hdd drives to store my data.
I have the following questions:
1. Is it good drive layout? Can I have mirrored root pool using only
2 320 hdd-s?
It's one option. As long as you don't mind having no parity for your
root pool on the 80G disk. And yes, you can create a mirrored root
pool using only the 320G disks.
That's great that I can do mirrored pool using only 2 320 disks, So I
will save 80gb disk for something else.
If I create mirrored root pool using only 2 320 disks will I be able to
recover easily in case of one disk failure?
I mean it will like:
1. remove failed hdd from the pool.
2. remove it physically
3. install new one physically
4. add new disk into the pool
and everything will be rebuilt and my root mirrored pool will be ready?
2. Will I be able create pool at the install time or I should do it
afterwards?
The installer will create the root pool for you on whatever disk you
choose. You will have to setup the mirror after installation. See the
ZFS documentation on how to do that.
Ok I will look at it.
3. My motherboard Asus P5B Deluxe has 2 controllers. Should I
connect 320 hdd-s to separate sata port of the each controller to
achieve better safety/performance?
IIRC sata doesn't have this sort of guideline like old IDE interfaces
did. In IDE land, you wanted to seperate out the controllers you used
so that you weren't blocked when making requests to drives on the same
controller. Sata did away with this limitation.
I undesrtand, but will it be faster or slower to use two separate
controllers?
Cheers,
