I'm currently upgrading to Infernalis and the chown stage is taking a log time on my OSD nodes. I've come up with this little one liner to run the chown's in parallel
find /var/lib/ceph/osd -maxdepth 1 -mindepth 1 -print | xargs -P12 -n1 chown -R ceph:ceph NOTE: You still need to make sure the other directory's in the /var/lib/ceph folder are updated separately but this should speed up the process for machines with larger number of disks. Nick
