Hi. When I shutdown or halt my laptop, I see error messages like: [FAILED] Failed unmounting /root. [⋮] [FAILED] Failed unmounting /var/cache. [⋮] [ OK ] Reached target Unmount All Filesystems. [ OK ] Reached target Final Step. Starting halt...
My Nextcloud public folder has a screenshot: https://cloud.disroot.org/s/MFaEoozaHHJjtbs I suppose these Btrfs subvolumes do still get unmounted cleanly before shutdown, because: 1. The success message "[ OK ] Reached target Unmount All Filesystems." 2. When the laptop turns back on, I don't see any message about unclean filesystem. 3. In the output of ~smartctl -a /dev/nvme0n1~, the field "Unsafe Shutdowns" dos not increase. Am I thinking correctly, and can I safely disregard those error messages?
