I did not see the autoexpand property in this pool. zpool is v13, zfs is v3. > > No. You will need to reboot the system in order for the extra space to become usable in the pool. Or, if none of the OS is installed on the pool, you can export/import the pool to make the new space available. Ok, at least it grows on export/import, so I don't need to create a new pool and copy everything over. Thanks for the info! Benhelp
