Hi all,
I have a cluster in jewel which is upgraded from hammer , I want to migrate
ms_type to async, but I can't find documents about it. Does somebody know how
to do that?
Thanks

You just have the set the config option ("ms_type = async", I think?) and
restart daemons. Both messengers use the same protocol and there's no
migration in terms of data or setting up compatibility.

Hi Greg,
Can I restart daemons one by one online? Or there will be a down time before I
restart all daemons?
Thanks

Yes, you can (and should!) restart them one at a time to avoid downtime.

I’ve test that, and yes. The cluster works fine with some node using
async-message while others using simple-message.
Thank you, Greg.

Hi Greg,

Well I can absolsulty try that or I can even make a mix of SPDK and non SPDK
OSDs and test them individually
I just wanted to know how stable is it and if I could use it as RocksDB
Thanks for the help

Hi,
setting the pplication pool helped - the performance is not skewed anymore
( i.e. SSDpool is better than HDD)
However latency when using more threads is still very high
I am getting 9.91 Gbits/sec when testing with iperf
Not sure what else should I check
As always, your help will be greatly a
Hey Eugen,
Pleasure. Glad you problem resolved itself.

Hello,
We are running Luminous 12.2.2. 6 OSD hosts with 12 1TB OSDs, and 64GB
RAM. Each host has a SSD for Bluestore's block.wal and block.db.
There are 5 monitor nodes as well with 32GB RAM. All servers have
Gentoo with kernel, 4.12.12-gentoo.
When I export an image using:
rbd export pool-name/
Yesterday I noticed some OSDs were missing from our cluster (96 OSDs total,
84up/84in is what showed).
After drilling down to determine which node and the cause, I found that all the
OSDs on that node (12 total) were in fact down.
I entered 'systemctl status ceph-osd@$osd_number' to determine e

The first and hopefully easy one:
I have a situation where I have two pools that are rarely used (the third will
be in use after I can get through these issues), but they need to present at
the whims of our cloud team. Is there a way I can turn off ‘2 pools have many
more objects per pg than av

The doc at
http://docs.ceph.com/docs/master/ceph-volume/lvm/prepare/#ceph-volume-lvm-prepare
says I can pass a physical device to ceph-volume. But when I try to do that:
gentooserver ~ # ceph-volume lvm create --bluestore --data /dev/sdb
usage: ceph-volume lvm create [-h] [--journal JOURNAL] --dat
Did you wipe all of the existing partitions and such first? Which version
of ceph? The below commands are what I ran to re-add my osds as bluestore
after moving all data off of them.
ceph-volume lvm zap /dev/sdb
ceph-volume lvm create --bluestore --data /dev/sdb

Hi,
We have set no scrub , no deep scrub flag on a ceph cluster.
When we are deleting snapshots we are not seeing any change in usage space.
I understand that Ceph OSDs delete data asynchronously, so deleting a
snapshot doesn’t free up the disk space immediately. But we are not seeing
any change
Hi List,
I read a old article about how ceph client read from ceph cluster.It said the
client only read from the primary osd. Since ceph cluster in replicate mode
have serveral copys of data only read from one copy seems waste the performance
of concurrent read from all the copys.
But that artci
Hi Peter,
Not sure if you have got to the bottom of your problem, but I seem to have
found what might be a similar problem. I recommend reading below, as there
could be a potential hidden problem.
Yesterday our cluster went into *HEALTH_WARN* state and I noticed that one
of my pg's was listed a
