Hi:
I am using ceph nautilus with CentOS 7.6 and working on adding a pair of
iscsi gateways in our cluster, following the documentation here:

I was in the "Configuring" section, step #3, "Create the iSCSI gateways"
and ran into problems. Whe

Exactly. Should I create a tracker issue? I think this is not hard to reproduce

Hi Eric,

Yes. For all EC pools located in datacenter ServerRoom, we currently set

logical but not physical, disks in these buckets are co-located such that

I believe it is stored locally on the monitor host. Saving the cluster map into
RADOS would result in a chicken or egg problem.
This is supported by the following two sections in the docs:

Do you have any monitor / OSD logs from the maintenance when the issues
occurred?

All seems in order in terms of your CRUSH layout. You can speed up the
rebalancing / scale-out operations by increasing the osd_max_backfills on each
OSD (Especially during off hours). The unnecessary degradation is not expected
behavior with a cluster in HEALTH_OK status, but with backfill / re
I really would not focus that much on a particular device model.
Yes, Kingston SSDs are slower for reads, we knew that since we tested them.
But that was before they were used as block.db devices, they first were
intended purely as block.wal devices. This was even before bluestore

Thank you Gregor for the reply. I have read that page. It does say what a Crush

the map is stored in the system. Is it replicated on all OSD, vis a distributed

All seems in order then - when you ran into your maintenance issue, how long
was if after you added the new OSDs and did Ceph ever get to HEALTH_OK so it
could trim PG history? Also did the OSDs just start back up in the wrong place
in the CRUSH tree?

Here's some more insight into the issue.

backup pool that serves as Openstack cinder-backup storage, performing
