This may be the case on file systems created before 2014. A a result of failing to mount the user will land in the initramfs busybox. Manually trying to mount will display the failing inodes. Unfortunately the built-in (in initramfs) btrfs checker from btrfs- progs 5.2.1 can not repair this problem. That is related to this patch for btrfs-progs 5.3-rc1: https://lore.kernel.org/linux- btrfs/eb937822-50fb-1515-9407-f5a4e4b06...@gmail.com/T/#mfa319e441efe5a3b66955891ed61ed47e33bf543 As a work around after the upgrade the user should boot the old (disco) kernel and should be made aware not to remove this. As a more permanent resolution then linux-oem can be installed. In principle a script can be devised to save the failing inodes with new, or when available btrfs-progs could be updated to 5.3 to repair the file system. In any case it should be considered that the failing inodes might be present on multiple snapshots of the fs. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ferry 2280 F.... pulseaudio DistroRelease: Ubuntu 19.10 HibernationDevice: RESUME=UUID=72896b7c-29c8-4560-af37-7ebda2e01c1a InstallationDate: Installed on 2012-11-19 (2526 days ago) InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.1) IwConfig: lo no wireless extensions. eth1 no wireless extensions.
