Hello DRBD Community,
How is it possible to make a System Backup and Restore of a DRBD cluster node? I'm looking for an easy disaster recovery method without the need of installing, setting up the system and drbd. The disk scheme is as following: /dev/cciss/c0d0p1 = /boot /dev/cciss/c0d0p2 = / with LVM (entire disk) and LV's: - system / - . Application and Data LV's, that are mirrored with the remote cluster peer via DRBD I could imagine that an sector based method (e.g. dd or IFL) will work, but it will need a lot of time and will produce a huge image if you save the entire disk to an image. One idea is to backup & restore MBR, partition table/disk scheme, LVM, system LV only. After connecting the desaster recovered node, it must be replicated from the allive node with current data and applications anyway. But I dont know how to make this kind of selective sector based backup & restore and if this ist the right method for DRBD. Thanks for hints and regards Steffen
