Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Ok, found a way:

debnode2:~# drbdadm down db
debnode2:~# drbdadm -- :::::1:::: set-gi db
set GI to  

Write new GI to disk?
[need to type 'yes' to confirm] yes

debnode2:~# drbdadm up db
debnode2:~# /usr/lib/heartbeat/ResourceManager takegroup drbddisk

Why not add a simple "drbdadm uptodate" to drbdadm to issue the 
corresponding commands ?

This would simplify the commands.
