Using a slice for the root pool

Added by Geoff Nordli about 1 year ago

I am building a smaller storage box with 6 disks in it and I don't want to allocate two of the disks just for the root pool, but I do want to have a separate data and root pools. My main concern is losing those two disks worth of IO.

I believe i can partition a couple of the disks to create a mirrored vdev for the root, let's say 30GB.

Then I could allocate the rest of the disk to be used with the data pool.

What are the downsides to doing this?

thanks,

Geoff

You cannot do that using Nexenta (so far, at least). Only mirroring of whole disks is supported by the installer for the root pool.

You may consider running NCP from a mirrored pool of 2 x USB Thumbdrives. This solution works fine for me since over one year and it doesn't cost a valuable SATA port.

Hi Patrick.

That would work, though it doesn't look very professional if it were a customer deployment.

Depending on the server, I was also thinking about using a compact flash to IDE adapter, which plugs directly into the motherboard.

Some of the new Dell servers have a space right on the mobo to plug in a flash card.

thanks,

My system has two 8GB PicoUSB drives plugged into an adapter that sticks them right on a motherboard header. It's compact and unless the client opens the system they won't even know they're there.

That is very slick, I really like the USB adapter.

It looks like it is pretty low profile as well.

thanks,
