[Gentoo] Disappearing ext2/ext3 filesystems

Mittwoch, 03. Februar 2010

Sometime in the past few days I discovered that my media partition wasn’t mounted anymore (ext3 FS). Also my root partition (ext4 FS) wasn’t listed under /dev/ anymore.

The only clue I got was from /var/log/messages:
EXT3-fs: sda2: couldn’t mount because of unsupported optional features (240).

It seems that udev >= 150 doesn’t like the deprecated sysfs stuff very much (apparently it took over it functions).
To keep it short: I had to uncheck the kernel modules SYSFS_DEPRECATED_V2 (also you should uninstall SYSFS_DEPRECATED), rebuild and install the kernel and everything worked again
