Hi,
according to http://docs.ceph.com/docs/luminous/rbd/qemu-rbd/ the use of
Discard/TRIM for Ceph RBD disks is possible. Openstack seems to have
implemented it
(https://www.sebastien-han.fr/blog/2015/02/02/openstack-and-ceph-rbd-discard/).
In oVirt there is no option "Enable Discard" for Cinder Disks (when
choosing IDE or VirtIO-SCSI driver), even when i set
"report_discard_supported = true" in Cinder. Are there plans for
supporting this in the future? Can i use it right now with custom
properties (never tried this before)?
thx
matthias
