DRBD does not (yet) support consistency bundling of several drbd. so whenever you have a connection loss, your four devices will disconnect in a slightly different order. consistency of your stripe set cannot be guaranteed. I also think you'd get better performance out of drbd on top of raid. -- : Lars Ellenberg Tel +43-1-8178292-0 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Vivenotgasse 48, A-1120 Vienna/Europe http://www.linbit.com : __ please use the "List-Reply" function of your email client.
