I think (have not checked the PROTO versions) that -pre8 is _not_ protocol compatible to 0.7.x . (But simply compare the PROTO versions, you can find them in the changelog and /proc/drbd. There are a few fixes for 64 bit aches that were commited into SVN after 0.7.5. I guess you should wait a week till I release 0.7.6 [ Or you convince me to do it faster... :) ] -Philipp -- : Dipl-Ing Philipp Reisner Tel +43-1-8178292-50 : : LINBIT Information Technologies GmbH Fax +43-1-8178292-82 : : Schönbrunnerstr 244, 1120 Vienna, Austria http://www.linbit.com :
