Re: Clearing Incomplete Clones State

[Lazuardi Nasution <mrxlazuardin@xxxxxxxxx>]

Hi,

Additional information. It seem that snapshot state is wrong. Any idea on my case? How to manually edit pool flags for removing "incomplete_clones" flag?

[root@management-b ~]# rados -p rbd ls

rbd_directory

[root@management-b ~]# rados -p rbd_cache ls

rbd_directory

[root@management-b ~]# rados -p rbd lssnap

0 snaps

[root@management-b ~]# rados -p rbd_cache lssnap

0 snaps

Best regards,

Hi,

I have removed cache tiering due to "missing hit_sets" warning. After removing, I want to try to add tiering again with the same cache pool and storage pool, but I can't even the cache pool is empty or forced to clear. Following is some output. How can I deal with this? Is it possible to clear "incomplete_clones" and "snapshot state"? How to avoid "missing hit_sets" warning to appear again?

[root@management-b ~]# ceph osd tier add rbd rbd_cache

Error ENOTEMPTY: tier pool 'rbd_cache' is not empty; --force-nonempty to force

[root@management-b ~]# ceph osd tier add rbd rbd_cache --force-nonempty

Error ENOTEMPTY: tier pool 'rbd_cache' has snapshot state; it cannot be added as a tier without breaking the pool

[root@management-b ~]# rados -p rbd_cache ls

rbd_directory

[root@management-b ~]# rados -p rbd lssnap

0 snaps

[root@management-b ~]# ceph osd dump | grep rbd_cache
