Greetings,
You need to set the following configuration option under [osd] in your
ceph.conf file for your new OSDs.
[osd]
osd_crush_initial_weight = 0
This will ensure your new OSDs come up with a 0 crush weight, thus preventing
the automatic rebalance that you see occuring.
Good luck,

Hi all,
We've 8 osd hosts, 4 in room 1 and 4 in room2.
A pool with size = 3 using following crush map is created, to cater for room
failure.

max_size 4

Background: I'm running single-node Ceph with CephFS as an experimental
replacement for "traditional" filesystems. In this case I have 11 OSDs,
1 mon, and 1 MDS.
I just had an unclean shutdown (kernel panic) while a large (>1TB) file
was being copied to CephFS (via rsync). Upon bringing the system

Any idea when 12.2.10 is going to be here, please?

Previous (partial) node failures and my current experiments on adding a
node lead me to the fact that, when rebalancing are needed, ceph
rebalance also on intra-node: eg, if an OSD of a node die, data are
rebalanced on all OSD, even if i've pool molteplicity 3 and 3 nodes.
This, indeed, make per
Hi Daniel, thanks a lot for your help.
Do you know how I can recover the data again in this scenario since I lost
1 node with 6 OSD?
My configuration had 12 OSD (6 per host).

Dear Igor
Thank you for your help!
I am working with Florian.
We have built the ceph-bluestore-tool with your patch on SLES 12SP3.
We will post back the results ASAP.
