FreeBSD 11.2-RELEASE was released a few days ago. This means it’s time to upgrade the FreeBSD running on my nas.
For the most part, this was all what I did:
# freebsd-update -r 11.2-RELEASE upgrade # freebsd-update install # reboot # freebsd-update install
After it’s been upgraded, I also need to update the Zpool.
root@nas:~ # zpool status pool: zroot state: ONLINE status: Some supported features are not enabled on the pool. The pool can still be used, but some features are unavailable. action: Enable all features using 'zpool upgrade'. Once this is done, the pool may no longer be accessible by software that does not support the features. See zpool-features(7) for details. scan: scrub repaired 0 in 0h0m with 0 errors on Tue Jan 23 23:54:42 2018 config: NAME STATE READ WRITE CKSUM zroot ONLINE 0 0 0 gpt/zfs0 ONLINE 0 0 0 errors: No known data errors
Let’s upgrade the zpool as suggested:
root@nas:~ # zpool upgrade zroot This system supports ZFS pool feature flags. Enabled the following features on 'zroot': device_removal obsolete_counts zpool_checkpoint If you boot from pool 'zroot', don't forget to update boot code. Assuming you use GPT partitioning and da0 is your boot disk the following command will do it: gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0 root@nas:~ #
Next is to update the boot code. If for whatever reason you’re following this step to update zpool (zroot) on your FreeBSD, make sure you know what is your boot disk is. In my case, it’s not
da0. To find out run the following command:
root@nas:~ # gpart show => 34 488397101 ada4 GPT (233G) 34 1024 1 freebsd-boot (512K) 1058 4194304 2 freebsd-swap (2.0G) 4195362 484201766 3 freebsd-zfs (231G) 488397128 7 - free - (3.5K)
ada4, and the partition the boot sits on is
root@nas:~ # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada4 partcode written to ada4p1 bootcode written to ada4
To upgrade non-zroot zpool, just run
zpool upgrade pool_name.
