Hi,

the stray replicas will be automatically removed in the background.

Sorry bout that

It's all set now, i thought that was replica count as it is also 4 and 5 :)

I can see the changes now

[root@controller-node ~]# ceph osd dump | grep 'replicated size'

pool 4 'images' replicated size 2 min_size 2 crush_ruleset 0 object_hash rjenkins pg_num 1024 pgp_num 1024 last_change 19641 flags hashpspool stripe_width 0

pool 5 'volumes' replicated size 3 min_size 2 crush_ruleset 0 object_hash rjenkins pg_num 512 pgp_num 512 last_change 19640 flags hashpspool stripe_width 0

[root@controller-node ~]#

To my other question, will it remove the excess replicas?

Hi,

My replication count now is this

[root@controller-node ~]# ceph osd lspools
4 images,5 volumes,

Those aren't replica counts they're pool ids.

[root@controller-node ~]#

and I made adjustment and made it to 3 for images and 2 to volumes to 3, it's been 30 mins now and the values did not change, how do I know if it was really changed.

this is the command I executed

 ceph osd pool set images size 2
 ceph osd pool set volumes size 3

ceph osd pool set images min_size 2
ceph osd pool set images min_size 2


Another question, since the previous replication count for images is 4 and volumes to 5, it will delete the excess replication right?

Thanks for the help
