Почему у md1 в UUID пишется (local to host wowubuntu) ?


Re: RAID Вопрос насчёт UUID

Возможно, дело в этом: http://neil.brown.name/blog/20060521092609

The core idea is to report the host name of each raid array. mdadm can then assemble every array that it can find, providing it is for 'this' host.

Но я не уверен.
