@ksurent after some additional investigation, it was determined that thin_ls is not safe to run for the purposes of periodic statistics gathering due to its potentially high I/O load that can max out the disk for long periods of time.

It was disabled completely in https://github.com/openshift/origin/pull/12822, until we can either improve thin_ls or find a alternative way to get the information.

That hasn’t been backported yet but probably should be. @derekwaynecarr ?

Any chance this will be backported to 1.4.x ?
