When creating an array, the homehost will be recorded in the superblock. For version-1 superblocks, it will be prefixed to the array name. For version-0.90 superblocks, part of the SHA1 hash of the hostname will be stored in the later half of the UUID. When reporting information about an array, any array which is tagged for the given homehost will be reported as such. **** When using Auto-Assemble, only arrays tagged for the given homehost will be assembled. **** ---------------------------- So just once stop your array and manually assemble it like mdadm -A --homehost= --update=homehost and from the next reboot on, that array, too, will automatically be assembled by the linux kernel.
