Hi Luis,
What i mean , we have three OSD with Harddisk size each 1TB and two
pool (poolA and poolB) with replica 2. Here writing behavior is the confusion
for us. Our assumptions is below.
PoolA -- may write with OSD1 and OSD2 (is this correct)
PoolB -- may write with OSD3 and OSD1 (is this correct)
suppose the hard disk size got full , then how many OSD's need to be added and
How will be the writing behavior to new OSD's
After added few osd's
PoolA -- may write with OSD4 and OSD5 (is this correct)
PoolB -- may write with OSD5 and OSD6 (is this correct)
Regards
Prabu

I don't understand your question? You created a 1G RBD/disk and it's full. You
are able to grow it though - but that's a Linux management issue, not ceph.
As everything is thin-provisioned you can create a RBD with an arbitrary size -
I've create one with 1PB when the cluster only had 600G/Raw available.

Hi All,
Also please find osd information.
ceph osd dump | grep 'replicated size'
pool 2 'repo' replicated size 2 min_size 2 crush_ruleset 0 object_hash rjenkins

Hi All,
We need to test three OSD and one image with replica 2(size 1GB). While
testing data is not writing above 1GB. Is there any option to write on third
OSD.
ceph osd pool get repo pg_num
pg_num: 126
# rbd showmapped
id pool image snap device

Dear Team,
We are using two ceph OSD with replica 2 and it is working properly.
Here my doubt is (Pool A -image size will be 10GB) and its replicated with two
OSD, what will happen suppose if the size reached the limit, Is there any
chance to make the data to continue writing in another two OSD's.
Regards
Prabu
