Hi,
We noticed that if one set an osd crush weight using the command
ceph osd crush set $id $weight host=$host
it updates the osd weight on $host bucket, but does not update it on
the "class" bucket (${host}~hdd or ${host}~ssd), and as a result the
old weight is still used until one runs `ceph osd crush reweight-all`
or do some other changes that cause the crushmap recalculation.
The same behaviour is for `ceph osd crush reweight-subtree <name> <weight>`
command.
Is it expected behavior or should I report a bug to the tracker?
I would consider this is ok if I knew a way how to set a weight for a
"class" (xyz~hdd or ~ssd) bucket. When I try to use ${host}~ssd it
complains about invalid chars ~ in the bucket name.
