I had to force my computer to shut down (by holding the power button) and now I cannot login. The machine boots to a default unthemed SDDM login screen that is different to the normal one, and I can enter my password, but nothing happens when I press Enter.
I can boot to Recovery Mode, access the disk from the terminal, navigate the directories and run various commands. The problem is something to do with LVM (Logical Volume Management). Something about the disk/volume management seems to have been corrupted or deleted.
When I run pvscan it returns "No matching physical volumes found". Running lvscan or vgscan returns no information. Running some other commands gives "No logical volumes detected" and "No volume groups found". I think they were lvdisplay and vgdisplay.
Yet the disk is accessible from terminal and all the files and directories are there, so the Partition table is not corrupted nor is the disk.
I also ran fsck from the Recovery Mode menu and it returned this:
"/lib/recovery-mode/recovery menu: line 80: /etc/default/rcS: No such file or directory
fsck from util-linux 2.3.9.3
/dev/sdb2 is mounted
e2fsck: Cannot continue, aborting."
When I run fdisk -f it returns information on all the storage devices and their partitions. Running fdisk -l returns this comment in red "Partition 1 does not start on physical sector boundary." But this is after the listing for a hard disk that only has data on it, and does not seem to be part of the problem as I can access it from Windows.
In System Summary (accessed through Recovery Mode) everything reports normal except this:
= = = LVM state = = =
Physical Volumes: not ok (BAD)
Volume Groups: ok (good) [However I believe this is because it does not detect any Volume Groups.]
My computer setup:
I am running kubuntu 24.04 that I installed a few weeks ago on one SSD (238 GB Vi550). (It was working perfectly until I had to force shut-down a few day ago.)
I have Windows 10 installed on another different SSD (932 GB Samsung 860 EVO).
I have 2 other data disks, one SSD and one Hard Drive.
Processor Intel(R) Core(TM) i5-14600K 3.50 GHz
Installed RAM 32.0 GB (31.8 GB usable)
Storage 932 GB SSD Samsung SSD 860 EVO 1TB, 932 GB SSD Samsung SSD 980 1TB, 238 GB SSD Vi550 S3 SSD, 3.64 TB HDD ST4000DM004-2U9104
Graphics Card NVIDIA GeForce RTX 3050 (6 GB), Intel(R) UHD Graphics 770 (128 MB)
System Type 64-bit operating system, x64-based processor
Pen and touch Pen support
Does anyone know what is the problem here or how to fix it?
