Do you mean that thin Sreyan> pools cannot be migrated to from older LVMs ? I don't think so. The two versions of LVM thin pools aren't compatible. See the archives of this list for more details. I also don't quite trust them either with my data. Sreyan> Or are you trying to have the ability to take snapshots of your system Sreyan> to make rollbacks easier? Sreyan> Yes. You might want to think about using 'btrfs' instead, since it supports filesystem level snapshots, and I think Ubuntu 20.x or newer uses it for it's default filesystem now. I'm pretty sure Linux MINT does as well. But this will require you to copy the data off the current setup (if you can get it working again) and onto new disks. A full re-install of the OS will be needed. Not that I truest brtfs either quite yet. Nor do I like the mashing of various storage layers into one unified whole (like ZFS does) though I understand why they feel they need to do it.

I'm more of a Debian guy at home and a CentOS/RHEL guy at work.

Sreyan> No. You're probably toast. Can you boot off a rescue disk, or even a recent Fedora bootable ISO and poke around at your current setup? That might let your recover your data. Of course before you do that, you should copy the original disk onto a new disk on save the original somewhere offline and unpowered, so you can run tests on the copy of the data.
