I'm trying to add a new storage host into a Ceph cluster (quincy 17.2.6). The
machine has boot drives, one free SSD and 10 HDDs. The plan is to have each HDD
be an OSD with a DB on a equal size lvm of the SDD. This machine is newer but
otherwise similar to other machines already in the cluster
and sent for
moderation. It never got approved or rejected. So I moved on, can't be using
something that does NOTHING with no way to proceed past that point.

Hello guys,
We are running Ceph Octopus on Ubuntu 18.04, and we are noticing spikes of
IO utilization for bstore_kv_sync thread during processes such as adding a
new pool and increasing/reducing the number of PGs in a pool.
It is funny though that the IO utilization (reported with IOTOP) is 99.99
I would say drop it for squid release or if you keep it in squid, but going to
disable it in a minor release later, please make a note in the release notes if
the option is being removed.
Just my 2 cents :)
Best regards,
Sake

The disks are 14.9, but the exact size of them does not matter much in this
