Read-only flag stands on two nodes.
I will use a cluster file system (ocfs2 of gfs2) for the correct operation of the two disks

Hi
I installed 8.4.1 drdb.
The cluster operates on a primary/primary mode.
However, the drives are mounted in the mode of read-only

Why not activate the read-write mode?
Config:
[root at noc-1-synt /]# cat /etc/drbd.d/r0.res
# create new

startup {
