Hello, Gentoo. My system isn't booting. In particular, most of the SSD partitions won't mount, because they are not under /dev any more. The root partition, /dev/md125 mounts, but that is all.
These partitions are lvm partitions under RAID-1 (software RAID). They simply fail to appear in /dev/mapper on boot up. (I don't remember the exact error message, here). I've managed to bring my system up using a Rescue-DVD followed by chroot. This shows that the partions on the SSD are basically undamaged. I strongly suspect that my emerge update from last night is to blame. There, lvm2-2.03.17-r1 was reinstalled after other packages (dependencies) were updated. The order of these packages, taken from /var/log/emerge.log was: 1. dev-libs/mpfr-4.1.1_p1 2. dev-lang/mujs-1.3.2 3. sys-apps/util-linux-2.38.1 4. sys-apps/systemd-utils-251.10 5. dev-python/installer-0.6.0 6. app-text/lib-paper-2.0.4 7. app-misc/ca-certificates-20211016.3.86 8. sys-fs/lvm2-2.03.17-r1 .. There were a few more packages after that, a total of 23. If any of these is relevant, then it is surely 3. or 4. lvm2 itself was merely rebuilt. I've had a quick scan of the gentoo bugzilla, but not found anything relevant there. Please help me get my system booting again! Thanks! -- Alan Mackenzie (Nuremberg, Germany).
