Hi all,
We’re trying to stop and then restart our ceph cluster. Our steps are as
following:
stop cluster:
stop mds -> stop osd -> stop mon
restart cluster:
start mon -> start osd -> start mds
Our cluster will stuck in cephfs degraded and mds is replaying journal. After
restart
Hello ceph users,
I get the following output when I execute the ceph health detail command.
Could anyone assist me for that problem/warning? Thanks.
HEALTH_WARN 41 pgs backfill_wait; 2 pgs backfilling; 23 pgs degraded; 21
pgs recovery_wait; 23 pgs stuck degraded; 64 pgs stuck unclean; 2 pgs stuck
Thanks for clarifying, would have been nice to protect against admin
mistakes. Argument "--exclusive" is not available in jewel version of
rbd-nbd. So I'd better be careful with those rbd volumes :-)

Hello,
my cluster didn't have MDS. I recommended add "ceph osd set noout" before

Hi Cephers.
We try to get "metadata search" working on our test cluster. This is one of two things we promised an internal customer for a very soon to be stared PoC... the second feature is, as I wrote already in another post, the "object expiration" (lifecycle?!) [object's should be auto-remo
Below steps are taken from redhat documentation:
Follow the below procedure for Shutting down the Ceph Cluster:
1.Stop the clients from using the RBD images/Rados Gateway on this
cluster or any other clients.
2.The cluster must be in healthy state before proceeding.
3.Set the noout, no
Thanks for the suggestions. There turned out to be an old testing pool
with replication of 1 that was causing the issue. Removing the pool
fixed the issue.

That limit has been removed for kernel versions that don't have a bug [1].

Hi Jason,
I've tried to do enable the lttng tracing but no success.
I have done the steps from [1] and [2] but nothing happened ...
It's difficult to catch the event to dump the objecter requests because when we
observe the event, this is already past away.
Kind regards,

Hello,
I am setting up a 9 node ceph cluster. For legacy reasons I'm using Ceph giant
(0.87) on Fedora 21. Each OSD node has 4x4TB SATA drives with journals on a
separate SSD. The server is an HP XL190 Gen 9 with latest firmware.
The issue I'm seeing is that only 2 drives get detected and mount
The issue is now fixed, it turns out i have unnecessary iptables rules,
flushed and deleted them all, restarted the OSDs and now they are running
normally.

Hi Melzer,
Somewhat pointing out the obvious, but just in case: Ceph is in rapid
development, and Giant is way behind where the state of the art is. If
this is your first Ceph experience, it is definitely recommended you

Perhaps ceph-deploy can Work when you disable the "epel" Repo?
Purge all and try it again.

Hi Federico,
Yep I understand that. This is for legacy reasons. We already have 3 older
clusters running with a similar setup with minor differences (hardware, etc.)
and this one is being setup to test something [:(]
Thanks

Hi Anton,
I'm not sure exactly what you're trying to do. If you want to delete
everything and start over, then just remove the zones, zonegroups and
realms on both sides, and remove their pools.
If you have a master zone you want to keep, but you want to remove the
non-master zone that is mirror

Do the rados bindings exist for python3?
I see this sprinkled in various areas..

This being said, I can not find said package

Hello Peter,
Thank you for your answer.
In our setup we have the virtual machines running in KVM, and accessing the
ceph storage using librbd.
The rbd cache is set to "writethrough until flush = true". Here it is the
result of ceph config show | grep cache :
# ceph --admin-daemon
/run/ceph/gue
You don't need to recompile that tool. Please see
``ceph_erasure_code_benchmark -h``.
Some examples are:
