Hi Ceph Users,
I deploy development cluster using vstart with 3 MONs and 3 OSDs.
On my experiment, Kill one of the monitor nodes by its pid. like this:
$ kill -SIGSEGV 27557
After a new monitor leader is chosen, I would like to re-run the monitor
that I've killed in the previous step. How do I
Hello,
Can we use rbd journaling without using rbd mirroring in Jewel ? So that
we can set rbd journals on SSD pools and improve write IOPS on standard
(no mirrored) RBD images.
Assuming IOs are acknowleged when written to the journal pool.
Everything I read regarding RBD journaling is relate
Looks like they are having major challenges getting that ceph cluster
running again.. Still down.

Hi,
I am evaluating RGW Multisite for disaster recovery.
I created us-east zone(master) and us-west zone in us zone group.
how can I see replication status:
which object is not replicated yet,replicating or replicated?
When one zone is down, I can not compare object list for each zone.
So this i
HI Chris,
That's an interesting point, I bet the managed switches don't have jumbo
frames enabled.
I think I am going to leave everything at our colo for now.

I see on this list often that peering issues are related to networking
and MTU sizes. Perhaps the HP 5400's or the managed switches did not
have jumbo frames enabled?
Hope that helps you determine the issue in case you want to move the
nodes back to the other location.

Hi David,
VLAN connectivity was good, the nodes could talk to each other on either
their private or public network. I really think they were doing something
weird across the fiber, not and issue with Ceph or how it was setup.
Thanks for the help!

There is a config option to have a public and private network configured on
your storage nodes. The private is what they would use to talk to each other
to do backfilling and recovery while the public is where clients access the
cluster. If your servers were able to communicate with each other

Thanks for your reply! I finally figured out that our issue was with the

You're right that you could be fine above the warning threshold, you can also
be in a bad state while being within the threshold. There is no one size fits

First I'm addressing increasing your PG counts as that is what you specifically
asked about, however I do not believe that is your problem and I'll explain
that later.
There are a few recent threads on the ML about increasing the pg_num and
pgp_num on a cluster. But if you learn how to search

I would actually recommend the exact opposite configuration for a
high-performance, journaled image: a small but fast SSD/NVMe-backed
pool for the journal data, and a large pool for your image data.
With the librbd in-memory, writeback cache enabled, the IO operations
will be completed as soon as
