Hi Lars,

Thanks for the suggestion to upgrade from 8.0.2 to 8.0.3.

Unfortunately this hasn't fixed my problem.  Writing to partitions 
whilst in re-sync still results in DRBD becoming 'stalled'.  Which, as I 
explained before, is a terminal condition requiring a power-cycle to 
unlock.  However this does not occur with protocol 'C':

version: 8.0.3 (api:86/proto:86)

Sorry to report such errors!

Just another very small error.  The 'man' for drbdadm reports the 
command: 'invalidate_remote'.  This should of course be 'invalidate-remote'.

Thanks for the help, I hope it's not too much of a problem,
