Subject: Re: Activating OSDs takes foreverI got these exact same error messages on my RHEL build. It did however seem that my OSD’s were correctly built and brought online. Never got to the bottom of these errors though.
There were others on this forum that had similar issues, and theirs too seemed to be working successfully despite the apparent problems during activation.

Subject: Activating OSDs takes forever
Hi All,
I had a pretty good run until I issued a command to activate OSDs. Now I am back with some more problemsL. My setup is exactly like the one in the official ceph documentation:
http://ceph.com/docs/master/start/quick-ceph-deploy/
That means, I am just using node2:/tmp/osd0 and node3:/tmp/osd1 as OSDs. I am running 64-bit CentOS-6-4.
I was able to prepare OSDs fine but when I am activating them it just takes forver (15 mins and counting):
[ceph@ceph-admin-node-centos-6-4 mycluster]$ ceph-deploy osd activate ceph-node2-osd0-centos-6-4:/tmp/osd0 ceph-node3-osd1-centos-6-4:/tmp/osd1

Why is ceph-deploy throwing bunch of errors when all I did was to create directories under /tmp on both nodes and issue a command to prepare them without any problems. I mean I can always delete the /tmp/osd0-1 and re-issue the commands again but I am wondering if anyone else has been this before?
is sending output to `stderr` it will show as ERROR in ceph-deploy's logging.
just logging something that is not really an error but somehow it is going to `stderr`.
