LINSTOR

Answering my own question. :grin:

Found this drbd-9.2.13-rc.1 announcement addressing an issue with lvm-thin:

LINSTOR sets the
rs-discard-granularity when the backing devices are thinly provisioned
(lvm-thin or zfs-thin).

I don’t quite understand what it’s about and there’s nothing more to read about it in the release notes of drbd-9.2.13, but maybe I should give it a try.
