I also don't really understand why crush selects OSDs with weight=0
....
host prox-ceph-3 {
id -4 # do not change unnecessarily
# weight 3.630
alg straw
hash 0 # rjenkins1
item osd.4 weight 0
}
root default {
id -1 # do not change unnecessarily
# weight 21.780
alg straw
hash 0 # rjenkins1
item prox-ceph-1 weight 7.260
item prox-ceph-2 weight 7.260
item prox-ceph-3 weight 0
item prox-ceph-4 weight 7.260
}
...
but crushtool --show-utilization still reports the OSD is used:
device 4: 59
Why?
