reveal? Any pre-v0.94.4 hammer OSDs running as the error states?

Yes, as this is the first one I tried to upgrade.
The other ones are running hammer

Thanks

Hi,

I did change the ownership to user ceph. In fact, OSD processes are running

If I run one of the osd increasing debug

this is what I get in logs

It seems the osd is running but ceph is not aware of it

Thanks

Make sure the OSD processes on the Jewel node are running. If you didn't change the ownership to user ceph, they won't start.

Hi all,

I'm upgrading ceph cluster from Hammer 0.94.9 to jewel 10.2.6.

The ceph cluster has 3 servers (one mon and one mds each) and another 6 servers with
12 osds each.
The monitoring and mds have been succesfully upgraded to latest jewel release, however
after upgrade the first osd server(12 osds), ceph is not aware of them and
are marked as down

If I run this command with one of the down osd
ceph osd in 14
osd.14 is already in.
however ceph doesn't mark it as up and the cluster health remains
in degraded state.

Do I have to upgrade all the osds to jewel first?
Any help as I'm running out of ideas?

Thanks
Jaime
