The following field needs to be provided on the command line due to corruption in the superblock: transaction id

You're using a wrong input. The pool metadata volume for PVE should be /dev/mapper/pve-data_tmeta, so here's what you need:

lvchange -ay pve/data_tmeta
thin_dump --repair /dev/mapper/pve-data_tmeta

It's also recommended to run thin_check on a faulty metadata:

thin_check /dev/mapper/pve-data_tmeta

Once you've finished the jobs, bring down the metadata volume:

lvchange -an pve/data_tmeta
