Question: does it need to be a raw partition or can it just be space inside one of the file systems on a DRBD device? on my system I have one partition that is used for the /var/lib/nfs stuff and perhaps in the future some NIS files but on the whole I am realizing I made it way bigger than needed for just nfs. /dev/nb0 3.7G 33M 3.5G 1% /nfsstate lets see 7 DRBD devices * 128MB =~896MB... yep enough space but is it the right type? Also, after changing to 0.7.? on both nodes will we need to restore from a backup or, will the physical partition content layout be the same? -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter
