My setup is different to yours but not totally different. I run ESXi 8, and I started to use BTRFS on some of my VM’s.
I had a power failure, that was longer than the UPS could handle. Most of the system shutdown safely, a few VM’s did not. All of the EXT4 VM’s were easily recovered (including another one that was XFS). TWO of the BTRFS systems crashed into a non recoverable state.
Nothing I could do to fix them, they were just toast. I had no choice but to recover using backups. This made me highly aware that BTRFS is still not a reliable FS.
I am migrating everything from BTRFS to something more stable and reliable like EXT4. It’s simply not worth the headache.
