Hello List,
i am wondering if there is meanwhile an easy method in ceph to find
more information about rbd-images.
For example I am interested in the modification time of an rbd image.
Do you mean some metadata changing? such as resize?
If you mean metadata changing, I think this command would be enough:
$ rados -p rbd stat rbd_header.11e3238e1f29
rbd/rbd_header.11e3238e1f29 mtime 2017-03-23 19:31:52.000000, size 0
Or any write to this image?
But if you want this one, I am afraid it's not so handy currently. maybe
going through the all data blocks of this image and sorting the mtime
of them would be workable.
Thanx
Yang
I found some posts from 2015 that say we have to go over all the
objects of an rbd image and find the newest mtime put this is not a
preferred solution for me. It takes to much time and too many system
resources.
Any Ideas ?
Thanks
Christoph
