Hi

Can someone please help with how to recover from the below back checksum errors:

lvconvert --repair /dev/pve/data
terminate called after throwing an instance of 'base::checksum_error'
what(): bad checksum in space map bitmap (block 289)
Child 347585 exited abnormally
Repair of thin metadata volume of thin pool pve/data failed (status:-1). Manual repair required!

lvchange -ay /dev/pve/data
bad checksum in space map bitmap (block 260)
Check of pool pve/data failed (status:1). Manual repair required!

How can I fix this?
