8.9.2 is the utils version, what is the kernel module version? (8.3.x/8.4.x/9.0.x)?
It's possible something paused sync, but I doubt it. You can try 'drbdadm resume-sync all'. The oos number should change constantly, any time a block changes it should go up and every time a block syncs it should go down. What protocol are you using?
