That means that the size parameter to pass to > drbdsetup's resize is that size + exactly 128 MB (in K). fdisk -s gives you the size of the partition, not the "filesystems's exact size", so it will give you the size of drbd, no hint of where to shrink to. but you typically tell the "resize filesystem" operation, to which size you want to resize to. then, that should be the size. btw, you do NOT want to resize a drbd with internal meta data. really. use external meta data (that is easy on lvm). -- : 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.
