In the rescue system, the array was then available as /dev/md/md_root. Booting the production system, the array became /dev/md/realhostname:md_root. mdadm --detail says Name : realhostname:md_root (local to host realhostname) Is this how things are supposed to work? I had the impression that the host name part of the array name only shows up in /dev/md/ if it DOES NOT equal the local host name of the running system?
