We are going towards mirror snapshots, but we didn't advertise
internally so far and we won't enable it on every images; it would only
be for new volumes if people want explicitly that feature. So we are
probably not going to hit these performance issues that you suffer for
quite some time and the scope of it should be limited...
thanks for all the informations
we tried snapshot based on friday again. after 30 images, the high load
came back.
i do not understand, whats happened.
6 days, before the problem started, we added one ssd per host.
but there were no problems. but 1 week later performance went down.
we are running completely out of ideas.
actually, we try journal based again.
the space is growing and we will wait and see, if there is a limit.
do you have any idea, how we can get the space back?
i think about something like, resync the images, who are behind the
master.
is somebody else outside, who uses the rbd mirror replication with ceph?
