I'm sure you are able to read changelogs, they are referenced from http://www.drbd.org/home/releases/ as for "simple use-cases, nothing fancy": as long as nothing goes wrong, you probably won't notice any bugs: "normal operation" is pretty easy. but when something goes wrong, and the software stack that is supposed to cover up for the failures gets stuck in some bugs known and fixed since 18 month, you might be better off without any "HA" features. -- : Lars Ellenberg http://www.linbit.com : : DRBD/HA support and consulting sales at linbit.com : : LINBIT Information Technologies GmbH Tel +43-1-8178292-0 : : Vivenotgasse 48, A-1120 Vienna/Europe Fax +43-1-8178292-82 : __ please use the "List-Reply" function of your email client.
