ext4 partition rescue after volume group deletion

YakoYakoYokuYoku

During a boot rescue I've accidentally remove my SolusSystem volume group (instead of deactivating it) and by consequence my logical volumes (Swap and Root). I couldn't save my LVM config. Although I still have my physical volume intact I don't think I'd want to recreate my LVs like os-installer. Maybe doing an fsck.ext4 at a superblock and try to transfer the lost+found but I ain't have any further ideas.

testdisk can recover data and to my knowledge partition tables.

For the 4.2 or 4.3 Solus release. I accidentally installed a pre-release Solus ISO to the wrong drive during testing. Wiping a terabyte of data that I had no backup for. I did not try restore the partition, just the data to a separate drive. But I did manage to recover all of it. Maybe it can help?

Harvey I've tried testdisk for scan already an obtained relevant superblocks, maybe I could use the suggested ext2fsck that it suggests. But now I have to find a disk to do the migration 🤔

Doesn't boot, but I've managed to restore the valued data of my partition (I think the first sectors went kapoot), can be considered fixed then. Thanms for the help Harvey

P.S.: After deleting a volume group (with vgremove) and completely lost your LVM configs you'll have to recreate your SolusSystem vg (vgcreate) and your Swap (lvcreate with 4 Megabytes not Mebibytes in Solus' case) plus Root (lvcreate with a -l 100%FULL arg, your configs may vary), then you look for your best superblocks of your Root partition (either testdisk or e2fsprogs) and run a fsck on that partition, get the corresponding UUIDs of the lvs and edit /etc/fstab alongside /etc/kernel/cmdline.d/10-resume.conf and lastly you could either backup your data then install your OS again or update all your boot configs with clr-boot-manager update, boot, pray.
