Hello list,
I pre-created the pools we would use for when the SSD eventually come in. Not my
finest moment perhaps.
Since I knew the SSDs would be 32GB in size, I created 32GB slices on HDDs in
slot 36 and 44.

I read the other posts in this thread, they look fine. But still, I
thing you have bad concept. Generally, it is a good idea to separate
root pool from data, but as I understand, you have only one physical
disk.
I would install Solaris using ZFS as the root filesystem on the whole
disk

Thanks for your reply. These units are located at a remote site

Something occurs to me: how full is your current 4 vdev pool? I'm

yes, by adding another 3 vdevs, any writes will be biased towards the

Richard?). That is, if I'm doing a write that
