Re: basic single node set up issue on rhel6

["Mathew, Sijo (KFRM 1)" <sijo.mathew@xxxxxxxxxxxxxxxxx>]

Great, that fixed the issue of setting up the monitor, thanks. Now, I’ve got the monitor up and running in the server (target) machine. But during the process of setting up the OSD, I’m stuck with the following issue. Please advise. (I did create the directory in the target machine before attempting this from the admin machine.)

 

[host]$ ceph-deploy osd prepare ceph-server-299:/tmp/osd0

[ceph_deploy.osd][DEBUG ] Preparing cluster ceph disks ceph-server-299:/tmp/osd0:

[ceph_deploy.osd][DEBUG ] Deploying osd to ceph-server-299

[ceph_deploy.osd][ERROR ] udevadm trigger --subsystem-match=block --action="" returned 2

Thanks,

Hi,

 

Installed ceph-deploy_1.2.1 via rpm but it looks like it needs pushy>=0.5.2, which I couldn’t find in the repository. Please advise.

 

Can you try again? It seems we left out the new pushy requirement out and that should be fixed.

This looks like a very old version of ceph-deploy. Can you attempt to install a newer version?

We released version 1.2 to the Python Package Index and to our repos here:  http://ceph.com/packages/ceph-extras/rpm/

If you are familiar with Python install tools you could simply do: `sudo pip install ceph-deploy`, otherwise could you try with the RPM packages?

But, you mention the lack of internet connection, so that would mean that for `pip` it would be quite the headache to meet all of ceph-deploy's dependencies.

Can you try with the RPMs for version 1.2 and run again? 1.2 had a massive amount of bug fixes and it includes much better logging output.

Once you do, paste back the output here so I can take a look.

 

I saw a similar thread in the archives, but the solution given there doesn’t seem to be that clear.

 

http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-June/002344.html

 

I had to install all the rpms separately as the machines that I work with don’t have internet access and “ceph-deploy install“ needs internet access. Could someone suggest what might be wrong here?

 

Environment: RHEL 6.4, ceph 0.61

 

Thanks,

Sijo Mathew
