Hi all,
I have a small ceph cluster with just 2 OSDs, latest firefly.
Default data, metadata and rbd pools were created with size=3 and min_size=1
An additional pool rbd2 was created with size=2 and min_size=1
This would give me a warning status, saying that 64 pgs were
active+clean and 192 active+degraded. (there are 64 pg per pool).
I realized it was due to the size=3 in the three pools, so I changed
that value to 2:
# ceph osd pool set data size 2
# ceph osd pool set metadata size 2
# ceph osd pool set rbd size 2
Those 3 pools are empty. After those commands status would report 64 pgs
active+clean, and 192 pgs active, with a warning saying 192 pgs were
unclean.
I have created a rbd block with:
rbd create -p rbd --image test --size 1024
And now the status is:
# ceph status
cluster 3e91b908-2af3-4288-98a5-dbb77056ecc7

It seems like those 192 pgs didn't realize there's no need for a 3rd copy?
How can I fix this so that I get active+clean for all pgs?
Thanks a lot.
