TASK ERROR: lvremove snapshot

[sumshouse]

I want to remove an old snapshot.
The VM disk is stored in a thin-lvm.

()
  Cannot send messages to thin pool data-thinpool01-tpool (253:7) with read only metadata which needs check first.
  Failed to suspend data/thinpool01 with queued messages.
TASK ERROR: lvremove snapshot 'data/snap_vm-242-disk-1_CB' error:   Failed to update pool data/thinpool01.

The pool has 200GB space left.

Do you know how to fix this?
