Two of my three computers won’t boot after update

Two of my three computers won’t boot after update. For rootfs they use xfs on thin-provisioned lvm2 logical volumes. The thin pool fails a metadata check on boot and attempts at manual repair from the rescue shell fail. However, the pool is not damaged. SystemRescue iso activates all volumes automatically and with no errors. No data has been lost. I tried chrooting into the systems and reverting lvm2 and linux61 to the previous versions. Didn’t work. Does anyone know what I should try reverting to get my computers working again? I can convert them to btrfs like my working system if I need to, but I’d rather avoid the hassle.
