this and keep it all bluestore
2. we only use the cluster for RBDs.

the storage be divided up?
The big questions are:
* 1 pool, or multiple,and why
* many RBDs, few RBDs, or single RBD per pool? why?

Interesting.
I thought when you defined a pool, and then defined an RBD within that pool..
that any auto-replication stayed within that pool?
So what kind of "load balancing" do you mean?
I'm confused.

No, you obviously don't need multiple pools for load balancing.

P
, and then go hand manage the slicing?
ceph-volume lvm create --data /dev/sdc --block.wal /dev/sdx1
ceph-volume lvm create --data /dev/sdd --block.wal /dev/sdx2
ceph-volume lvm create --data /dev/sde --block.wal /dev/sdx3
?
can I not get away with some other more simplified usage?

Interesting. What did the partitioning look like?

I had seen various claims here and there about how ceph would just
automatically figure things out, but I hadnt seen any real world examples.
Thank you for posting.

high
performance group, and allocate certain RBDs to only use that set of disks.
Pools, only control things like the replication count, and number of placement
groups.
I'd have to set up a whole new ceph cluster for the type of behavior I want.
Am I correct?

Sounds very useful.
Any online example documentation for this?
havent found any so far?

Yes I saw that thanks.
Unfortunately, that doesnt show use of "custom classes" as someone hinted at.

only goes as high as about 60% on a per-device basis.
CPU is idle.
Doesnt seem like network interface is capped either.
So.. how do I improve RBD throughput?

The odd thing is:
the network interfaces on the gateways dont seem to be at 100% capacity
and the OSD disks dont seem to be at 100% utilization.
so I'm confused where this could be getting held up.
