Re: > 2. Inefficient chown documentation - The documentation states that one should "chown -R ceph:ceph /var/lib/ceph" if one is looking to have ceph-osd ran as user ceph and not as root. Now, this command would run a chown process one osd at a time. I am considering my cluster to be a fairly small cluster with just 30 osds between 3 osd servers. It takes about 60 minutes to run the chown command on each osd (3TB disks with about 60% usage). It would take about 10 hours to complete this command on each osd server, which is just mad in my opinion. I can't imagine this working well at all on servers with 20-30 osds! IMHO the docs should be adjusted to instruct users to run the chown in _parallel_ on all osds instead of doing it one by one. I suspect the docs are playing it safe there, Ceph runs on servers of widely varying scale, capabilities, and robustness. Running 30 chown -R processes in parallel could present noticeable impact on a production server. — Anthony _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
