[Pacemaker] cannot create gfs2 filesystem : can't open device /dev/drbd1: Read-only file system

[Soni Maula Harriz]

hello all,
i'm a newbie in clustering
i've been following "cluster from scratch" tutorial, edition 5. everything
goes well until drbd section.
but, when i step ahead into "conversion to active/active", i follow
"cluster from scratch" tutorial, edition 3 because i use 2 centos 6.3
servers.
and there is a problem :
when i ran
'mkfs.gfs2 -p lock_dlm -j 2 -t cluster:web /dev/drbd1'
this message appear 'can't open device /dev/drbd1: Read-only file system'

in node 1 :
[root at cluster1 ~]# cat /proc/drbd

i've been googling, but the solution i found can't resolve mine.
any help would be appreciated
