I have a question. I have a disk that solaris 10& zfs is installed. I wanted
to add the other disks and replace this with the other. (totally three others). If
I do this, I add some other disks, would the data be written immediately? Or only
the new data is mirrored? Or I should use snapshots to replace that?
If you add a disk as a mirror, it will be resilvered as an exact copy (mirror!)
of the original.
I'm sure Ian meant "attach a disk as a mirror" rather than "add" :-). In ZFS
terminology "attach" is used for mirrors (RAID-1) and "add" is used for
stripes (RAID-0)
Good catch Richard!
