I am using DRBD 8.3.0 with CENTOS-5.3 and GFS in DUAL PRIMARY MODE.
after following the steps given at
http://wiki.samba.org/index.php/6.0:_DRBD i am able to configure it
successfully but problem comes if network between my both servers breaks
and both become unknown to each other

after giving command 

cat /proc/drbd both shows

 cat /proc/drbd 
version: 8.3.0 (api:88/proto:86-89)
GIT-hash: 9ba8b93e24d842f0dd3fb1f9b90e8348ddb95829 build by root at VIVEK,
2009-07-14 17:13:45
 0: cs:StandAlone ro:Primary/Unknown ds:UpToDate/DUnknown   r---
    ns:112 nr:344116 dw:344228 dr:5916 al:4 bm:21 lo:0 pe:0 ua:0 ap:0
ep:1 wo:b oos:0

1 . In this condition both the servers are not able to access gfs
mounted partition.
2. I don't know how to sync them again when network connectivity is
regained keeping both of them in primary mode.

Please help.
