Hey guys and girls, newbie question here (still in planning phase).
I'm thinking about starting out with a mini cluster with 4 nodes and
perhaps 3x replication, because of budgetary reasons. In a few months or
next year, I'll get extra budget and can extend to 7-8 nodes. I will
then want to change to EC 4:2.
But how does this work? Can I create a new pool on the same cluster with
the different policy? And can I move rbd-images across while they are
mounted without user impact? Or do I need to unmount the images, more
the images to another pool and then mount again?
Angelo.
