When creating a ZFS pool, it seems the default format is striping. But is there
a way to create a pool of concatenated disks? That is, let's say I have 2 local
disks (SATA, 100GB each) and 1 iscsi partition (from remote Solaris server,
80GB).
So, if I issue a command:
# zpool create -f mypool c0t1d0 c0t2d0 c2t010000E0815E35D500002A0049313F80d0
(for example)
I would get 'mypool' that is 280GB in size, right? But this would be in striped
mode. As a stripe, if any one of the disks were to fail, mypool would be toast.
But, if mypool was a concatenation, things would get written onto the c0t1d0
first, and if any one of the subsequent disks were to fail, I should be able to
recover everything off of mypool, as long as I have not filled up c0t1d0, since
things were written sequentially, rather than across all disks like striping.
Is my understanding correct, or am I totally off the wall here?
And, if I AM correct, how do you create a concatenated zpool?
