I would recommend the latter solution.

I think it may be caused by the change of "images" pool id, right?
Is it possible to re-reference the rbds in "volumes" on new "images" pool? Or
is it possible to change or specify the pool id of new pool?
Any suggestions are very welcome. Thanks

Hi Jason,
This really did the trick!
I can now rescue my rbds, thank you very much!

Now we are still struggling with this problem.

I think I created 25600 pgs totally, but ceph -s reported 25600 / 51200
randomly. However ceph -w always reported 51200 on the latest line.
If this a kind of bug or just I was doing something wrong? Feel free to let me
know if you need mo
ilure.

Hi Greg,
Sorry I didn't reserve the environment due to urgent needs.
However I think you are right because at that time I just purged all pools and
re-create them in a short time, thank you very much!

Hi Daniel,
If you deploy your cluster by manual method, you can specify the OSD number as
you wish.
Here are the steps of manual deployment:

You should switch to the branch you are using.

Hello,
I suggest Prometheus
withceph_exporter(https://github.com/digitalocean/ceph_exporter)and Grafana
(UI). It can also monitor the node's health and any other services you want.
And it has a beautiful UI.

Hi List,
Three of our Ceph OSDs got unreasonably high latency right after the first
second of the new year (2017/01/01 00:00:00 UTC, I have attached the metrics
and I am in UTC+8 timezone). There is exactly a pg (size=3) just contains these
3 OSDs.
The OSD apply latency is usually up to 25 min
Hi ,
I'm glad to know that it happened not only to me.
Though it is unharmful, it seems like kind of bug...
Are there any Ceph developers who know how exactly is the implementation of
"ceph osd perf" command?
Is the leap second really responsible for this behavior?
Thanks.
Since
Hi List,
I am testing the stability of my Ceph cluster with power failure.
I brutally powered off 2 Ceph units with each 90 OSDs on it while the client
I/O was continuing.
Since then, some of the pgs of my cluster stucked in peering
pgmap v3261136: 17408 pgs, 4 pools, 176 TB data, 5082 kobject
from different host after
20.072026>= grace 20.00)
But that OSD was not dead actually, more likely had slow response to
heartbeats. What I think is increasing the osd_heartbeat_grace may somehow
mitigate the issue.

Hi John,
rbd mirroring can configured by
pool.http://docs.ceph.com/docs/master/rbd/rbd-mirroring/
However the rbd mirroring method can only be used on rbd with layering feature,
it can not mirror objects other than rbd for you.

Hi,
Sorry I gave the wrong feature.
rbd mirroring method can only be used on rbd with "journaling" feature (not
layering).
