zfs send|zfs recv and am having trouble setting canmount=noauto on the recv side.I have tried
-o canmount=noauto and -o canmount=off and -x canmount while receiving the snapshot, but the canmount properties on the new datasets don't seem to be correct:
Code:
root@venus:/ # zfs send -c -v -R zroot@20241102_clone | zfs recv -u -o canmount=noauto backup/`hostname -s`
root@venus:/ # zfs send -c -v -R zroot@20241102_clone | zfs recv -u -x canmount backup/`hostname -s`
root@venus:/ # zfs send -c -v -R zroot@20241102_clone | zfs recv -u -o canmount=off backup/`hostname -s`
ccammack@venus:~ $ zfs get -r canmount backup | head -10

canmount properties be corrected at the end, or do I need to fix them with a script afterwards?If you needed to quickly clone a machine onto a fresh drive before going on vacation, how would you do it?
