And this construction is stable for you? How many drbd resources do you have running? On which hardware, with which kernel, if you don't mind me asking? I am currently running Debian etch on HP servers (with 3/4 GB RAM and raid1 storage backends for the volume groups - one at each node), but it's far from stable, and all crashes/hangs/reboots in the last few months were caused by drbd in one form or the other. best regards, Rene -- ------------------------------------------------- Gibraltar firewall http://www.gibraltar.at/ -------------- next part -------------- A non-text attachment was scrubbed...
