Hi all,
I want to change an osd with an bigger one and reweight the osd to 0:
ceph osd tree | grep osd.0
0 3.57999 osd.0 up 0 1.00000
cluster is healthy, but pg dump shows PGs which are primary on osd.0:
root@ceph-01:~# ceph pg dump | grep "\[0,"
dumped all in format plain

ceph -v
ceph version 0.94.2 (5fb85614ca8f354284c713a2f9c610860720bbf3)
Now the question, what PGs are this??
Is it save to destroy the OSD?
Any hints?
best regards
Udo
