Hallo Bradley, additionally to your question, I'm interesting in the following:
5) can I change all 'type' Ids because adding a new type "host-slow" to
distinguish between OSD's with journal on the same HDD / separate SSD? E.g.
from
type 0 osd
type 1 host
type 2 rack
..
to
type 0 osd
type 1 host
type 2 host-slow
type 3 rack
..
6) After importing the crush map to the cluster, how can I start rebalancing
all existing pools? (This is because all OSD now mixed up to other locations in
the crush hierarchy).
best regards
Danny

1) Do the ID's of the bucket types need to be consecutive, or can I make
them up as long as they are negative in value and unique?
2) Is there any way that I can control the assignment of the bucket type
ID's if I were to update the crushmap on a running system using the CLI?
3) Is there any harm in adding bucket types that are not currently used,
but assigning them a weight of 0, so they aren't used (a row defined, with
racks, but the racks have no hosts defined)?
4) Can I have a bucket type with no "item" lines in it, or does each
bucket type need at least on item declaration to be valid?
