Hi Strahli, Thank you for the quick answer! Sorry I have to ask again: as far as I can see, Gluster keeps all information about peers, bricks, in /var/lib/glusterd. So if I migrate to a new OS, it seems that I have to restore them. Or would you suggest rather to re-generate them by repeating all "peer probe ..." and "volume brick-add ..." commands?
