direct links of old sources may well be a few messages off.

your "/proc/drbd" does not match your log excerpt.
according to the log below,
you have been Primary Inconsistent (probably SyncTarget).

sorry, DRBD has no access to good data anymore,
and can only EIO any further requests.

there should also be something like
"Sorry, I have no access to good data anymore."
