Could you share the exact command you're trying and then also 'ceph auth get client.<CLIENT>'?

Hi,

I just got the same message in my lab environment (octopus) which I had redeployed. The client's keyring had changed after redeployment and I think I had a stale mount. After 'umount' and 'mount' with the proper keyring it worked as expected.

Hello All,

i recently tried to reactivate a CEPH Cluster that I setup last year. I applied patches regularly and did some tests afterwards which always worked.

Now I did run my usual tests again before getting it ready to use in production but I am not able to mount my cephfs shares anymore, I always run into the following error:

mount error: no mds server is up or the cluster is laggy

The ceph health is OK, I can reach all MDS Servers and all other servers aswell, the S3 Gateways is also still working. I did not find any errors within the logs that would help me debug this further.

As i want to learn how to debug those issues in the future I’d rather try to repair the cluster instead of just recreating it since I dont have any pressure to get it running again quickly.

Could you guys give me any hints on where to look further?

CEPH Version: 14.2.22
OS: CentOS7

Thanks in Advance,

Hendrik
