Hello,

i have two server with 2 local 10GB LUN'S on two different EMC Systems.

I've created a primary/primary /dev/drbd0 block device with the two LUN's 
as /dev/mapper/xxx devices and the /dev/drbd0 device syncronized fine.

After this i created a volgroup on the /dev/drbd0 device.

Finaly i try to create a Logvol with a gfs Partition and this unfortunatly 
failed.

The cluster configuration is ok, because they are running with a shared 
GFS on the same EMC Maschine.

My question now, is there a problem with emc san devices and drbd, because 
emc contraoller is an active/passive controller ?

Or do i have to switch to a primary/standby DRBD-Configuration.

Thanks
