Hi,
In order to use te online-verify feature of DrBD 8.2.5, you will have
to modify your configuration file to add a verify algorithm, as the
error message is warning you.
The easiest way of doing so is adding, in the global SYNCER or
specific ressource SYNCER section of /etc/drbd.conf, :
verify-alg "md5" ;
Adding this algo. will require a reload of your configuration. I've
used md5, but you might have faster / more appropriated algorithms
available on your system. You should check which ones are available
through your crypto API.
