| Find in which block the filesystem on your RBD image stores journal, find the object hosting this block in rados and use its mtime :-)
Jan
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). -Greg On Thursday, November 26, 2015, Christoph Adomeit < Christoph.Adomeit@xxxxxxxxxxx> wrote: Hi there,
I am using Ceph-Hammer and I am wondering about the following:
What is the recommended way to find out when an rbd-Image was last modified ?
Thanks
