Hello Jeff! Could you (or anyone else, of course *G*) please show me how?
Situation: There shall be 2 snapshots of a ZFS called rpool/rb-test Let's call those snapshots "01" and "02". $ sudo zfs create rpool/rb-test $ zfs list rpool/rb-test NAME USED AVAIL REFER MOUNTPOINT rpool/rb-test 18K 170G 18K /rpool/rb-test $ sudo zfs snapshot rpool/rb-t...@01 $ sudo zfs snapshot rpool/rb-t...@02 $ sudo zfs clone rpool/rb-t...@02 rpool/rb-test-02 $ sudo zfs promote rpool/rb-test-02 $ zfs list -r rpool | grep rb-test rpool/rb-test 0 170G 18K /rpool/rb-test rpool/rb-test-02 18K 170G 18K /rpool/rb-test-02 rpool/rb-test...@01 0 - 18K - rpool/rb-test...@02 0 - 18K - Now, what do I need to do, so that I get rpool/rb-test back to where it was when the snapshot rpool/rb-t...@01 was created, but WITHOUT losing what's at rpool/rb-t...@02? As there's no rpool/rb-t...@01, I obviously can't do a zfs rollback rpool/rb-t...@01. I suppose I might be able to do "zfs rollback rpool/rb-test...@01", but that would destroy rpool/rb-test...@02, wouldn't it? Could you please be so kind and show what exactly needs to be done?
