Hi I have a cluster which shares data using drbd. I would like to do a backup of some data on the secondary node each night. I thought this should work something like this: On the secondary node: drbdadm disconnect $res drbdadm primary $res mount -o ro /dev/$res /mnt cp /mnt/my_data /backup umount /mnt drbdadm secondary $res On both nodes: drbdadm connect $res But when I do this, I cannot get the drbd device to work again without invalidating the secondary and doing a complete resync from the primary node. Any hints? Is it possible at all? Regards Dominik
