Hello,
On a Nautilus cluster, I'd like to move monitors from bare metal servers to VMs
to prepare a migration.
I have added 3 new monitors on 3 VMs and I'd like to stop the 3 old monitors
daemon. But I soon as I stop the 3rd old monitor, the cluster stuck
because the election of a new monitor f

By "stop" you mean "stop and then immediately re
Note that with 6 monitors, quorum requires 4.
So if only 3 are running, the system cannot work.
With one old removed there would be 5 possible, then with quorum of 3.
Best regards,

Good point! I hadn't thought of that.
Looks like it works if I remove one, thanks a lot!

I don't know if it is that specifically, but they are all are running the
latest version of Luminous and I set the cluster to only allow Luminous
OSDs in. All services have been upgraded to Luminous. Do I need to run a
command to activate the cls_rgw API?

Hello,
is there any way to reset deep-scrubbed time for pgs?
The cluster was accidently in state nodeep-scrub and is now unable to
deep scrub fast enough.
Is there any way to force mark all pgs as deep scrubbed to start from 0
again?

If I make a directory in linux the directory has the date of now, why is
this not with creating a snap dir? Is this not a bug? One expects this
to be the same as in linux not

Hello List,
when i initially enable journal/mirror on an image it gets
bootstrapped to my site-b pretty quickly with 250MB/sec which is about
the IO Write limit.
Once its up2date, the replay is very slow. About 15KB/sec and the
entries_behind_maste is just running away:
root@ceph01:~# rbd --clus
There's an xattr for this: ceph.snap.btime IIRC

Hello,
I have a Nautilus cluster with a cephfs volume, on grafana, it shows that
cephfs_data pool is almost full[1] but if I give a look to the pool
usage, it looks like I have plenty of space. Which metrics are used by grafana?

Hmmm, but typing a ls -lart is faster than having to lookup in my manual
how to get such a thing with xattr. I honestly do not get the logics
about applying everywhere the same date as the parent folder. Totally
useless information stored. Might as well store nothing.

Hello Jason,
thanks for that fast reply.
This is now my /etc/ceph/ceph.conf

rbd_mirror_journal_max_fetch_bytes = 4194304
I stopped and started my rbd-mirror manually with:
rbd-mirror -d -c /etc/ceph/ceph.conf
Still same result. Slow speed shown by iftop and entries_behind_master

Hello Jason,
okay, good hint!
I did not realize, that it will write the journal 1:1 but that makes
sense. I will benchmark it later.
However, my backup cluster is the place where the old spinning rust
will find its last dedication.
Therefore it will never be as fast as the live cluster.

Yes, it's replaying the exact IOs again to ensure it's point-in-time consistent.

Hello,
I think I've been running into an rbd export/import bug and wanted to see if
anybody else had any experience.
We're using rbd images for VM drives both with and without custom stripe sizes.
When we try to export/import the drive to another ceph cluster, the VM always
comes up in a buste
Hi,
Are you exporting rbd image while a VM is running upon it ?
As far as I know, rbd export is not consistent
You should not export an image, but only snapshots:
- create a snapshot of the image
- export the snapshot (rbd export pool/image@snap - | ..)
- drop the snapshot

Hi
no need to craete a namespace. You just specify the namespace you want to
access.
See https://docs.ceph.com/docs/nautilus/man/8/rados/ the -N cli option
For access to a particular namespace have a look at the example here:
