hi.
i am trying to attach a mirror disk to my root pool. if the two disk are the
same size.. it all works fine, but if the two disks are with different size
(8GB and 7.5GB) i get a "I/O error" on the attach command.
can anybody tell me what am i doing wrong?

As queried by Ian, the new disk being attached must be at least as big
as the original root pool disk. It can be bigger, but the difference
will not be used in the mirroring.

Hi !
I've done the moves this morning, and the high service times followed the disks

So, I have 3 disks to replace urgently !

Replacing c7t2d0, I get the following :

Current status :

continue to function, possibly in a degraded state.

You can't do this at a pool level, but you can at a zfs/zvol level.
to prevent a filesystem or vol from being mounted at boot:
zfs set canmount=no
Anyone have any idea on this.
I wanted to separate out my VirtualBox VDIs so that I could activate
