according to http://www.linbit.com/fileadmin/linbit/DRBD-Factsheet.pdf the "Maximal overall size of all devices" as well as the "Maximal size of a single device ( 32bit / 64 bit )" is 4 TiB for DRBD 0.7 and DRBD 8.0. You would need the enterprise version DRBD+ when you need devices >4TiB. best regards, Werner On Fri, 2007-11-02 at 13:40 -0400, Desjardins, Kristian wrote: > I'm not sure if >4TB devices are supposed to work on x86_64 or not, but > they don't seem to.
