Hello list,
does rbd support trim / unmap? Or is it planned to support it?
Greets,
Stefan
librbd (and thus qemu) support it. The rbd kernel module does not yet.
See http://ceph.com/docs/master/rbd/qemu-rbd/#enabling-discard-trim
Thanks! Is there any recommanded value for discard_granularity? With
fstrim and iscsi i use 128kb.
