"ceph-disk trigger" invocation is currently performed in a mutually exclusive fashion, with each call first taking an flock on the path /var/lock/ceph-disk. On systems with a lot of osds, this leads to a large amount of lock contention during boot-up, and can cause some service instances to trip the 120 second timeout. Take an flock on a device specific path instead of /var/lock/ceph-disk, so that concurrent "ceph-disk trigger" invocations are permitted for independent osds. This greatly reduces lock contention and consequently the chance of service timeout. Per-device concurrency restrictions required for http://tracker.ceph.com/issues/13160 are maintained.
