hi all,


i have a problem in sync'ing 2 hosts. actually they dont even when i see in
the status, that all goes fine! for maintenance reasons i had to move my xen
from host xen001 to host xen002. after stopping xen001 and starting xen002 i
realized, that i had a 2 month old disk replication.


after stopping drbd and doing the "dd bs=4M if=/dev/vgmain/lv_server01 | ssh
-p 2222 root at 'dd bs=4M of=/dev/vgmain/lv_server01'" i had again
the latest copy onto the xen002 L


any glue in that?


thanks a lot, walter.
