Hi,
If the OSD represents the primary one for a PG, then all IO will be
stopped..which may lead to application failure..
no, that's not how it works. You have an acting set of OSDs for a PG,
typically 3 OSDs in a replicated pool. If the primary OSD goes down,
the secondary becomes the prim
Hi list,
I have encounter this problem both on jewel cluster and luminous cluster.
The symptom is some request will be blocked forever and the whole
cluster won't able to receive any data anymore. Further investigating
shows the blocked request happened on 2 osds(the pool size is 2 so I
guess it wi

Hi,
thats a bad news.
round about 5000 OSDs are affected from this issue. It's not realy a
solution to redeploy this OSDs.
Is it possible to migrate the local keys to the monitors?
I see that the OSDs with the "lockbox feature" has only one key for
data and journal partition and the older OSDs h
Hello, Ceph users,
is it possible to migrate already deployed Ceph cluster, which uses
public network only, to a split public/dedicated networks? If so,
can this be done without service disruption? I have now got a new
hardware which makes this possible, but I am not sure how to do it.
Hi Yenya,
Can I ask how your cluster looks and why you want to do the network
splitting?
We used to set up 9-12 OSD nodes (12-16 HDDs each) clusters using 2x10Gb
for access and 2x10Gb for cluster network, however, I don't see the reasons
to not use just one network for next cluster setup.
Thank
Yes sort of. I do have an inconsistent pg for a while, but it is on a
different pool. But I take it this is related to a networking issue I
currently have with rsync and broken pipe.
Where exactly does it go wrong? The cephfs kernel clients is sending a
request to the osd, but the osd never re
Hi,
due to performance issues RGW is not an option.
This statement may be wrong, but there's the following aspect to consider.
If I write a backup that is typically a large file, this is normally a
single IO stream.
This causes massive performance issues on Ceph because this single IO
stream is se
Hi,
we are having issues with the crush location hooks on Mimic:
we deployed the same script we have been using since Hammer (and has
been working fine also in Jewel) that returns:
root=fresh-install host=$(hostname -s)-fresh
however it seems the output of the script is completely disregarded.

Jakub,
we have deployed the Ceph cluster originally as a proof of concept for
a private cloud. We run OpenNebula and Ceph on about 30 old servers

How can I get the snapshot create date on cephfs. When I do an ls on
.snap dir it will give me the date of the snapshot source date.

Hi Ceph Community,
I am using ansible 2.2 and ceph branch stable-2.2, on centos7, to deploy
the playbook. But the deployment get hangs in this step "TASK [ceph-mon :

I have all the three ceph nodes ceph-admin, ceph-mon, ceph-osd

Hi,
How is the commercial support for Ceph? More specifically, I was recently
pointed in the direction of the very interesting combination of CephFS,
Samba and ctdb. Is anyone familiar with companies that provide commercial
support for in-house solutions like this?
