direct links of old sources may well be a few messages off.


Check the drbdadm man page...

drbdadm invalidate all   (Will invalidate the data on the node where you run the command)

drbdadm invalidate_remote all (Will invalidate the data on the other node where you run the command)

If you have several resources you may do then one at a time

drbdadm invalidate resource-name


from the man page:
-------------------------------------------------------------------
invalidate
               This forces DRBD to consider the data on the local backing storage  device  as  	 
out-of-sync. Therefor  DRBD will copy each and every block over from its peer, to bring the local 
storage device back in sync.

invalidate_remote
               This command is similar to the invalidate command, but the backing storage of  the 
peer  is invalidated and hence rewritten with the data of the local node.
-------------------------------------------------------------------
