This issue was solved by removing 'data-integrity-alg' from
from http://www.drbd.org/users-guide/re-drbdconf.html : 'We suggest to
use the data-integrity-alg only during a pre-production phase due to its
CPU costs. Further we suggest to do online verify runs regularly e.g.
once a month during a low load period.'
