I had a zpool we'll call 'testpool'.
testpool had 3 devices included in it, and a single zfs called 'test'.
I needed to move 'test' to a new, smaller pool. I wanted to name the new pool the same name 'testpool'.
Basically did the following.
zfs send testpool@backup > /tmp/test-dump zpool export -f testpool zpool create -f testpool newdevice zfs receive -F testpool < /tmp/test-dump
Unfortunately I found out that the testpool@backup snapshot was the wrong snapshot. Too old. I have yet to reallocate the three devices that were in the OLD testpool. (None of these 3 devices are 'newdevice', they are a separate 3.)
Is there any way I can recover data in those devices? I'm thinking since I named the new, smaller pool the same as the old zpool, I'm pretty much SOL. But if not, that would be nice to know.
Edit: More info
I did a 'zpool import' and got this.
bash-3.00# zpool import pool: testpool id: 14781458723915654709 state: ONLINE action: The pool can be imported using its name or numeric identifier. config: testpool ONLINE c5t8d0 ONLINE c5t9d0 ONLINE c5t10d0 ONLINE
So I'm guessing I just need the syntax to import this zpool using its numeric identifier, while giving it a new name.
