Hello,
I have a ceph nautilus cluster. The crushmap is organized with 2 rooms,
servers in these rooms and osd in these servers, I have a crush rule to
replicate data over the servers in different rooms.
Now, I want to add a new server in one of the rooms. My point is that I
would like to specify the room of this new server BEFORE creating osd in
this server (so the data added to the osd will be directly at the right
location). My problem is that it seems that servers appears in the
crushmap only when they have osds... and when you create a first osd,
the server is inserted in the crushmap under the default bucket (so not
in a room and then the first data stored in this osd will not be at the
correct location). I could move it after (if I do it rapidly, there will
be no that much data to move after), but I was wondering if there is a
way to either define the position of a server in the crushmap hierarchy
before creating osd or eventually to specify the room when creating the
first osd ?
