Thanks guys. I guess my questions was mostly an effort to try an understand how the ring reference affects local mounts.
If eg. two disks are mounted as: /dev/sda1 as /srv/node/disk1 /dev/sdb1 as /srv/node/disk2 If these are then umount and mounted as: /dev/sdb1 as /srv/node/disk1 /dev/sda1 as /srv/node/disk2 What will happen? Will the disks be resynced according to some reference in the ring or will they just continue to work with there respective objects/accounts/containers that are already stored on them?
