If you're still on bullseye (Debian 11), then Debian Backports may solve this. Install btrfs-progs 6.2-1~bpo11+1. The kernel from backports may also be required. Note that backports support for Debian 11 (bullseye) will probably end within the next six months, so please consider upgrading to Debian 12 (bookworm) at your earliest convenience. Regards, Nicholas
