My aim would be to have only one mount point, hence lvm on > top of drbd would be desired. the reason why it is not recommended is that you may run into funny things in the lvm part when only part of the drbd pvs are Primary on the node... and several TB of storage takes ages to initialize with current drbd 0.7. but as long as your heartbeat scripts do behave, and you generally know what you are doing, it is certainly possible to have lvm on top of drbd without problems. btw, drbd-plus can (currently) handle 16TB per device, and initializes much faster. you have to by a licence from linbit, but you get an implicit support contract for it, too. cheers -- : Lars Ellenberg Tel +43-1-8178292-0 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schoenbrunner Str. 244, A-1120 Vienna/Europe http://www.linbit.com : __ please use the "List-Reply" function of your email client.
