The problem can be > solved by making drbd1 to use a fresh new, unused drbd_meta_device[x]. meta data move is not implemented in drbd 0.7, and needs to be done by hand. dd might be friend or foe here. for example, kids do not try this at work, # move meta data from /dev/VG/md  to /dev/VG/md  dd if=/dev/VG/md bs=128M count=1 skip=5 of=tmp.md.5 dd of=/dev/VG/md bs=128M count=1 seek=3 if=tmp.md.5 you should NOT do this while drbd is running. and if this drinks your coffe, don't ask me why it did so :) but, if you are using LVM, please use one lv per md device. makes it all so much easier. and you can start from scratch with a simple dd if=/dev/zero bs=1M of=/dev/VG/drbd_XY_md -- : Lars Ellenberg Tel +43-1-8178292-0 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schoenbrunner Str. 244, A-1120 Vienna/Europe http://www.linbit.com : __ please use the "List-Reply" function of your email client.
