Out of interest, why do you need to use offline resize? I always have 
used the online resize with no issues (LVM underneath). Simply increase 
the LV (on both nodes) and then issue a "drbdadm resize <resource>" command.

Not sure if that helps, or if you have a reason for using offline 
resize, maybe someone else can assist with that.

PS, using 8.4.x versions.

Adam
