Hi
I am trying to upgrade from Mimic (13.2.10) to Octopus (15.x). Im also tryin
to sue cephadm and am following this
guide.https://docs.ceph.com/docs/master/cephadm/adoption/
It was all going fine until step 11 and deploying the new RGW's. I don't have
any realms set for my cluster, so how

Thanks for the information. I now consider myself well-advised.

My higher-ed organization is considering multi-day instructor-led training
similar to Red Hat's Ceph Storage "CEPH125" course, but perhaps based only
on the community codebase instead of the Red Hat Ceph Storage product.
Likewise if we were to plan or deploy a Ceph cluster using the community
Hi,
Do you have a running rpcbind service?
$ systemctl status rpcbind
NFSv3 requires rpcbind, but this dependency will be removed in a later release
of Octopus. I've updated the tracker with more detail.
Hope this helps,

As I said, these disks aren't that full as far as bytes are concerned.
But they do have a lot of objects on them! As I

Correct, "crush weight" and normal "reweight" are indeed very different.
The original post mentions "rebuilding" servers, in this case the correct
way is to use "destroy" and then explicitly re-use the OSD afterwards.
purge is really only for OSDs that you don't get back (or broken disks that

Ceph is from redhat and redhat is owned by IBM. I think the best
training you could get would be from RedHat.
I would not advise to learn how to use a mouse with a web interface nor
this ansible or some other deploy tool. Do it from scratch manually so
you know the basics. If you know
Hello, I am testing ceph from croit and it works fine: very easy web

Well, there's me, the docs guy that Sage hired.
What kinds of training would you like to see?

This is an issue that will happen regardless of pubsub configuration.

Are there reputable training/support options for Ceph that are not geared
toward a specific commercial product (e.g. "Red Hat Ceph Storage,") but
instead would cover the newest open source stable release?
Thanks,

Hi Lenz,
Hopefully this is the part that was required:
"tree": {
"nodes": [
{
"id": -1,
"name": "default",
"type": "root",
"type_id": 11,
"children": [

Sorry, allways the wrong button...
So I ran the command:
ceph orch apply nfs cephnfs cephfs.backuptest.data
And there is now a not working container:
ceph orch ps:

I'm trying to deploy nfs-ganesha with cephadm on octopus.
According to the docs, it's as easy as running the command in the docs:

Hi Marco,
looks like you have found a bug. It would be helpful to see the output
of the /api/health/full REST API call that is used to generate that tree
view.
You can obtain this via the dashboard's built-in API browser (click Help
icon -> API -> Health -> GET /health/full -> Try it out ->
As you have noted, 'ceph osd reweight 0' is the same as an 'ceph osd out', but
it is not the same as removing the OSD from the crush map (or setting crush
weight to 0). This explains your observation of the double rebalance when you
mark an OSD out (or reweight an OSD to 0), and then remove it
"reweight 0" and "out" are the exact same thing

Thank your reply
Our cluster are runing for two years in production,and it has no problem,so
we don't upgrade.
I check memory on host.Very little memory of free left.Does creating thread
failure have anything to do with this?
In addition to the kvm virtual machine, there are 22 osds on
