Now, that SSD isn't very new and has started developing some smart errors, so I thought I'd just remove it and find a nice recycle bin for it. However, this fails. This is Debian Buster (latest) with kernel 5.4 and lvm 2.03.02(2) Any idea how to get rid of this? # lvconvert --uncache data/data Unknown feature in status: 8 2488/262144 128 819192/819200 57263288 35277148 19955332 9916661 0 1 1 3 metadata2 writethrough no_discard_passdown 2 migration_threshold 2048 smq 0 rw - Flushing 1 blocks for cache data/data.
