Thanks very much, I can use this.
It would be nice if the balancer module had functionality to
check/cleanup these stale entries.
I may create an issue for this.

you can run 13.2.1 mds on another machine. kill all client sessions
and wait until purge queue is empty. then it's safe to run 13.2.2
mds.
run command "cephfs-journal-tool --rank=cephfs_name:rank

purge queue is empty when write_pos == expire_pos

I am also having this problem. Zheng (or anyone else), any idea how to
perform this downgrade on a node that is also a monitor and an OSD
node?

You either need to accept that reads/writes will land on different data
centers, primary OSD for a given pool is always in the desired data center,
or some other non-Ceph solution which will have either expensive, eventual,
or false consistency.

I see the point, but not for the read case:
no overhead for just choosing or let Mount option choose read replica.
This is simple feature that can be implemented, that will save many
people bandwidth in really distributed cases.
Main issue this surfaces is that RADOS maps ignore clients - they

Hi all,
We're using mimic and enabled multiple fs flag. We can do kernel mount of
particular fs (e.g. fs1) with mount option mds_namespace=fs1.However, this
is not working for ceph-fuse:
#ceph-fuse -n client.acapp3 -o mds_namespace=fs1 /tmp/ceph

Update.
So I rebuilt the osd with a separate DB partition on the ssd drive and
i/o to disks is what I expected, about ~3x the client I/O.

Hello,
I'm running some tests on pure SSD pool with mimic and bluestore.
Strange thing is that currently running fio into rbd images I'm
getting a huge difference client and disk I/O. For pure write
performance I'm seeing about ~20k iops on the client side and about
~300k on the ssd side. I have
Hi ceph-users,
Most of our servers have 24 hdds plus 4 ssds.
Any experience how these should be configured to get the best rgw performance?
We have two options:
1) All osds the same, with data on the hdd and block.db on a 40GB
ssd partition
2) Two osd device types: hdd-only for the rgw
Me and quite a few others have had high random latency issues with disk
cache enabled.

Looks like you’ve considered the essential points for bluestore OSDs, yep.
:)
My concern would just be the surprisingly-large block.db requirements for
rgw workloads that have been brought up. (300+GB per OSD, I think someone
saw/worked out?).

Hi Florian,
what's your Ceph version?
Can you also check the output for
ceph-bluestore-tool show-label -p
It should report 'size' labels for every volume, please check they
contain new values.
Thanks,
Igor

One consideration is that you may not be able to fit higher DB levels on
the db partition and end up with a lot of waste (Nick Fisk recently saw
this on his test cluster). We've talked about potentially trying to
pre-compute the hierarchy sizing so that we can align a level boundary
to fit
