So I'm in the process of upgrading my DRBD setup from DRBD 0.7 to DRBD 8.0 so that I can use GFS and two primaries on a two node cluster in order to allow two servers to share the same filesystem without having to serve them out via NFS and complicate things by having the servers mount themselves via NFS. After setting up DRBD on top of LVM via: pvcreate (on /dev/sda3) vgcreate <fsgroup> lvcreate -L <size> /dev/sda3 with the drbd.conf referring to the disks as: device /dev/drbd0 disk /dev/fsgroup/vol0 I was in the middle of figuring out another problem of not being able to create/upgrade the meta-disk (which turned out to be my confusing devices and resources) when I came across a couple of emails in the archives referring to that LVM on top of DRBD is the preferred way of setting things up. I assumed this meant to create the drbd device first and create the LVM off of that. ie. in drbd.conf: device /dev/drbd0 disk /dev/sda3 And then a: pvcreate /dev/drbd0 vgcreate <fsgroup> lvcreate -L <size> /dev/drbd0 However when I attempt the pvcreate I get the following error: Device /dev/drbd0 not found (or ignored by filtering) How do I get around this? (or was my first method really the preferred one?) ___________________________________________________ Dan Brown zu.com communications Design - Development - Programming ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ 324 Duchess Street Saskatoon, SK S7K 0R1 tel.1.306.653.4747 fax.1.306.653.4774 http://www.zu.com zu.com - now on your mobile device!
