Great, it works. now I remember I was trying to add host by hand while
'ceph osd crush set ...' failed (maybe command is wrong).
Another problem: is there any chance to change 'rack'? Or how to
create a new rack? If I have to create a new rack first, I made
mistake, or maybe buggy again.
Before change rack:
log3 ~ # ceph osd tree
dumped osdmap tree epoch 611
# id weight type name up/down reweight
-1 45 pool default
-3 45 rack rack0205
-2 33 host log3
0 3 osd.0 up 3
1 3 osd.1 up 3
2 3 osd.2 up 3
3 3 osd.3 up 3
4 3 osd.4 up 3
5 3 osd.5 up 3
6 3 osd.6 up 3
7 3 osd.7 up 3
8 3 osd.8 up 3
9 3 osd.9 up 3
10 3 osd.10 up 3
-4 12 host squid87-log13
11 3 osd.11 up 3
12 3 osd.12 up 3
13 3 osd.13 up 3
14 3 osd.14 up 3
Looks reasonable, but log3 miss set rack, I wanna change rack=rack0205
to rack=rack0206), reset use this command, but not works:
for i in {0..10}; do ceph osd crush set $i osd.$i 3 pool=data
datacenter=dh-1L room=room1 row=02 rack=rack0206 host=log3; done
