I see, but you went forward with that flag. Somebody set the flag.
I know that Redhat backports a lot of things to the 3.10 kernel, maybe

nobody have this problem?

Hello,
I have a cluster of 3 nodes, 3 OSD per nodes (so 9 OSD in total),
replication set to 3 (os each node has a copy).
For some reason, I would like to recreate the node 1. What I have done :
1. out the 3 OSDs of node 1, stop then, then destroy them (almost in the
same time)
2. recreate the new
I've done something similar. I used a process like this:
ceph osd set noout
ceph osd set nodown
ceph osd set nobackfill
ceph osd set norebalance
ceph osd set norecover
Then I did my work to manually remove/destroy the OSDs I was replacing,
brought the replacements online, and unset all of those o
Hello,
I have a CEPH cluster in luminous 12.2.10 dedicated to cephfs.
The raw size is 65.5 TB, with a replica 3, I should have ~21.8 TB usable.
But the size of the cephfs view by df is *only* 19 TB, is that normal ?
Best regards,
here some hopefully useful information :

Hello ceph-users. I'm operating a moderately large ceph cluster with
cephfs. We currently have 288 osd's, made up of all 10TB drives, and are
getting ready to migrate another 432 drives into the cluster (I'm going to
have more questions on that later). Our workload is highly distributed

Hey folks, I’m looking into what I would think would be a simple problem, but
is turning out to be more complicated than I would have anticipated. A
virtual machine managed by OpenNebula was blown away, but the backing RBD
images remain. Upon investigating, it appears
that the images still ha

Hi all
I'm seeing some behaviour I wish to check on a Luminous (12.2.10) cluster
that I'm running for rbd and rgw (mostly SATA filestore with NVME journal
with a few SATA only bluestore). There's a set of dedicated SSD OSDs
running bluestore for the .rgw buckets.index pool and also holding the

Dear Cephalopodians,
inspired by
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2019-January/032092.html I
did a check of the object-maps of our RBD volumes
and snapshots. We are running 13.2.1 on the cluster I am talking about, all
hosts (OSDs, MONs, RBD client nodes) still on CentOS 7.5.
