FreeBSD 12.0-RELEASE was released today, and that means it’s time to upgrade 2 of FreeBSD 11.2 machines to this latest version. One of my FreeBSD boxes is a desktop used at work, and the upgrade went well without any issues. In this post, I’m going to document how the upgrade is done on my nas server at home. First ensure that the FreeBSD is up to date: root@nas:~ # freebsd-update fetch src component not installed, skipped Looking up update.FreeBSD.org mirrors... 2 mirrors found. Fetching metadata signature for 11.2-RELEASE from update1.freebsd.org... done. Fetching metadata index... done. Inspecting system... done. Preparing to download files... done. No updates needed to update system to 11.2-RELEASE-p6. Begin to perform the upgrade: ...

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 zroot as suggested: ...

I have a FreeBSD server which used to run of a smaller SSD drive. When replaced with a larger capacity SSD by using dd command to clone the disk, there is free space allocated. I want to extend the existing zroot pool to use this space. The following describes how I achieve this with the help of a forum post. Let’s list some information about the zroot pool: root@nas:~ # zfs list zroot NAME USED AVAIL REFER MOUNTPOINT zroot 4.88G 50.8G 144K none List the partition scheme of the drive I’d like to extend my zroot zpool with: ...

Recently one of my servers that runs FreeBSD 11.1 keeps hanging on boot. Usually, the 2nd hard reboot will fix it. The root file system on this server is using ZFS and the ZFS pool report it as healthy. nas:~ # zpool status [136/462] pool: zroot state: ONLINE 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 So I’ve been reluctant to do anything about it. Until tonight, when I accidentally list the partition of that drive (ada4): ...

My main machine at home has been upgraded from Fedora 26 to 27 since the day the 27 was released. Everything has been working great, except the ZFS file system. I’m a ZFS-believer and I store my important files on ZFS-based storage. For a while there was no repository for Fedora 27 provided by zfsonlinux, until 6 days ago. I have been using packages provided for Fedora 26 as work around solution. If you’ve been using the ZFS packages for Fedora 26, you can upgrade to the ones for Fedora 27 now. ...
