Re: OSD activation issue

I was able to add a public_network line to the config on the admin host and push the config to the nodes with a "ceph-deploy --overwrite-conf config push rc-ceph-node1 rc-ceph-node2 rc-ceph-node3".  I was able to follow the quickstart after that without further incident.  Rzk had to take additional steps.  Search the list for his fix if mine doesn't help.

Thanks.   It does seem to be working ok and I can create / remove objects it seems without issues.

 

I am however having another problem.   In trying to add additional monitors to my cluster I am getting the following errors (note I did not see this when doing the first and currently only running monitor).   It seems to set it up fine, but then has problems starting it.

Hello Alistar

 

I also faced exactly same issue with one of my  OSD , after OSD Activate , progress got hanged but finally OSD gets added in cluster with no problem.

 

My cluster is running without knows issues as of now. If this is a test setup , you can ignore this , but keep an eye on this.

 

Regards

Hello all,

 

I am getting some issues when activating OSD’s on my Red Hat 6.4 Ceph cluster.  I am using the quick start mechanism so mounted a new xfs filesystem  and ran the “osd prepare” command.

 

The prepare seemed to be successful as per the log output below:

 

[ceph_deploy.cli][INFO  ] Invoked (1.2.7): /usr/bin/ceph-deploy osd prepare ldtdsr02se19:/osd2

[ceph_deploy.osd][DEBUG ] Preparing cluster ceph disks ldtdsr02se19:/osd2:

[ceph_deploy.osd][DEBUG ] Host ldtdsr02se19 is now ready for osd use.

 

When I ran the activate, however, I got the following:

 

[ceph_deploy.sudo_pushy][DEBUG ] will use a remote connection with sudo

[ceph_deploy.osd][INFO  ] Distro info: RedHatEnterpriseServer 6.4 Santiago

[ldtdsr02se19][ERROR ] create-or-move updating item name 'osd.1' weight 0.1 at location {host=ldtdsr02se19,root=default} to crush map

 

At this point, ceph-deploy just hung.  After waiting for many minutes, I had to kill it manually.   Looking at the OSD directory though, there is a lot of information that has been added there and when I do a “ceph health” it comes back as “HEALTH_OK”.

 

Is it really OK?

 

Thanks
