Re: Modification Time of RBD Images

[Gregory Farnum <gfarnum@xxxxxxxxxx>]

I don't think anything tracks this explicitly for RBD, but each RADOS object does maintain an mtime you can check via the rados tool. You could write a script to iterate through all the objects in the image and find the most recent mtime (although a custom librados binary will be faster if you want to do this frequently).

What is the recommended way to find out when an rbd-Image was last modified ?

Thanks
