Hi,
Is there any config on Ceph that block/not perform space reclaim? I test on one pool which has only one image 1.8 TiB in used.
rbd $p du im/root warning: fast-diff map is not enabled for root. operation may be slow. NAME PROVISIONED USED root 2.2 TiB 1.8 TiB
I already removed all snaphots and now pool has only one image alone. I run both fstrim over the filesystem (XFS) and try rbd sparsify im/root (don't know what it is exactly but it mentions to reclaim something) It still shows the pool used 6.9 TiB which totally not make sense right? It should be up to 3.6 (1.8 * 2) according to its replica?
Hi Istvan, Have you checked RBD trash? $ rbd trash ls -p im Thanks, Ilya
