What is the cluster status? The permissions seem correct, maybe the
OSDs have a problem?
Zitat von "Jens Hyllegaard (Soft Design A/S)" <jens.hyllegaard@xxxxxxxxxxxxx>:
I have tried mounting the cephFS as two different users.
I tried creating a user obuser with:
fs authorize objstore client.objuser / rw
And I tried mounting using the admin user.
The mount works as expected, but neither user is able to create
files or folders.
Unless I use sudo, then it works for both users.
The client.objuser keyring is:
client.objuser
key: AQCGodxfuuLxCBAAMjaSNM58JtkkUwO8UqGGYw==
caps: [mds] allow rw
caps: [mon] allow r
caps: [osd] allow rw tag cephfs data=objstore

Sorry, I was afk. Did you authorize a client against that new cephfs
volume? I'm not sure because I did it slightly different and it's an
upgraded cluster. But a permission denied sounds like no one is
allowed to write into cephfs.

I found out how to get the information:
client.nfs.objstore.ceph-storage-3
key: AQBCRNtfsBY8IhAA4MFTghHMT4rq58AvAsPclw==
caps: [mon] allow r
caps: [osd] allow rw pool=objpool namespace=nfs-ns

I am sorry, but I am not sure how to do that? We have just started
working with Ceph.

Oh you're right, it worked for me, I just tried that with a new path
and it was created for me.
Can you share the client keyrings? I have two nfs daemons running and
they have these permissions:
client.nfs.ses7-nfs.host2
key: AQClNNJf5KHVERAAAzhpp9Mclh5wplrcE9VMkQ==
caps: [mon] allow r
caps: [osd] allow rw pool=nfs-test namespace=ganesha
client.nfs.ses7-nfs.host3
key: AQCqNNJf4rlqBhAARGTMkwXAldeprSYgmPEmJg==
caps: [mon] allow r
caps: [osd] allow rw pool=nfs-test namespace=ganesha

On the Create NFS export page it says the directory will be created.

Hi,
is the path (/objstore) present within your CephFS? If not you need
to mount the CephFS root first and create your directory to have NFS
access it.

Hi.
We are completely new to Ceph, and are exploring using it as an NFS
server at first and expand from there.
However we have not been successful in getting a working solution.
I have set up a test environment with 3 physical servers, each with
one OSD using the guide at:
https://docs.ceph.com/en/latest/cephadm/install/
I created a new replicated pool:
ceph osd pool create objpool replicated
And then I deployed the gateway:
ceph orch apply nfs objstore objpool nfs-ns
I then created a new CephFS volume:
ceph fs volume create objstore
So far so good 😊
My problem is when I try to create the NFS export The settings are
as
follows:
Cluster: objstore
Daemons: nfs.objstore
Storage Backend: CephFS
CephFS User ID: admin
CephFS Name: objstore
CephFS Path: /objstore
NFS Protocol: NFSV3
Access Type: RW
Squash: all_squash
Transport protocol: both UDP & TCP
Client: Any client can access
However when I click on Create NFS export, I get:
Failed to create NFS 'objstore:/objstore'
error in mkdirs /objstore: Permission denied [Errno 13]
Has anyone got an idea as to why this is not working?
If you need any further information, do not hesitate to say so.
Best regards,
