That's a good point. If we do go with using UUID's as the sole representation internally, it might make sense to allow SysAdmins to manipulate UUID's in useful ways. Through the CLI, it could be something like this: gluster1> $ sudo gluster peer updateuuid mypeername NEW-UUID-VALUE peer alias update: success BUT... I don't yet understand the failure modes that people have mentioned around UUID's, so that's just an off-the-cuff thought rather than a deeply-thought-out-with-appropriate-wisdom one. :) + Justin > -- > Regards, > Stephan > > _______________________________________________ > Gluster-devel mailing list > Gluster-devel@xxxxxxxxxx > https://lists.nongnu.org/mailman/listinfo/gluster-devel -- Open Source and Standards @ Red Hat twitter.com/realjustinclift
