Hi Guys,
i've inherited a CephFS-Cluster, I'm fairly new to CephFS.
The Cluster was down and I managed somehow to bring it up again.
But now there are some Problems that I can't fix that easily.
This is what 'ceph -s' is giving me as Info:
[root@pcl241 ceph]# ceph -s
cluster cde1487e-f930-417a
I have completed the installation of ISCSI.
The documentation is wrong in several parts of it.
Is it anyway to contribute and update with right commands?
I found only
https://github.com/ceph/ceph/tree/master/doc
Which is inside the main Ceph project.
Should I use this to fix docs?

Figure out which OSDs are too full:
ceph osd df tree
Then you can either reduce their weight:
ceph osd reweight 0.9
Or increase the threshhold after which an OSD is considered too full for
backfills.
How this is configured depends on the version, i think in your version it
is still

Hi everyone again,
I continue set up of my testing Ceph cluster (1-node so far).
I changed 'chooseleaf' from 'host' to 'osd' in CRUSH map

I also set 'minimum_gateways = 1' for Ceph iSCSI gateway.

This is the problem right here. Your script is using the dm device
that belongs to an LV.
What you want to do here is destroy/zap

I cannot release this lock! This is an expansion shelf connected with
two cables to the controller. If there is no multipath management, the
os would see every disk at least twice. Ceph has to deal with it
somehow. I guess I'm not the only one who has a setup like this.

Hi all,
I have a cluster with 6 OSD nodes, each has 20 disks, all of the 120
disks are strictly identical (model and size).
(The cluster is also composed of 3 MON servers on 3 other machines)
For design reason, I would like to separate my cluster storage into 2
pools of 60 disks.
My idea is
Hi,
my ceph cluster has two pools and I reinstalled the osds of one complete

I was expecting when using

that this would lead to recovering the pool_a first (btw. I t

Not sure if you have been helped, but this is know issue if you have many
files/subfolder. It depends on what cephFS version you are running. This should
have been resolved in the Red Hat version 3 of ceph which is based on Luminous.
