Description Prasanna Kumar Kalever 2018-10-09 06:42:26 UTC
Description of problem:

gluster already has the support for discard/unmap/trim to underlying storage, we need to add unmap support in tcmu layer to get use of it.

Comment 8 Amar Tumballi 2019-06-20 09:22:08 UTC
At this time, when we have stabilized many things with gluster-block, I am fine with dropping this bug from next release, but planning to see what we need to test and validate to get newer TCMU-RUNNER in OCS3 repos should be worked out for future.

Ack to drop.
