I tried your suggestions, thanks.
But unfortunately it doesn't worked.
I don't have a split brain entry in my log.
I also get this error on the secondary I try to reconnect.
root@secondary ~ # cat /proc/drbd
version: 8.3.11 (api:88/proto:86-96)
srcversion: 71955441799F513ACA6DA60

ns:0 nr:0 dw:0 dr:0 al:0 bm:0 lo:1 pe:0 ua:0 ap:0 ep:1 wo:f oos:524280916
on the primary I see this
root@primary / # cat /proc/drbd
version: 8.3.7 (api:88/proto:86-91)
