Personally, I do not use them. Generally, I do not recommend using them. They are simply a way of avoiding learning about what you are doing. Bypassing the learning is the Red Hat Way; it is not my way. Also, you can get very unexpected results such as lacking any kernel support for hardware you use because the hardware wasn't plugged in or the module wasn't loaded when you did the configure. Stick to the manual way that keeps you on top of your system. @Klein

Hey Zordrak,

about new kernels (2.6.33 as example), there are new ways to get the modules compiled right?
you have already tried?
you will update this post to complain with new rules?

]]> Comment on High-Availability Storage with Slackware, DRBD & Pacemaker by Wheelybird http://blog.tpa.me.uk/high-availability-storage-with-slackware-drbd-pacemaker/comment-page-1/#comment-875 Wheelybird Tue, 02 Mar 2010 10:20:25 +0000 http://blog.tpa.me.uk/?page_id=179#comment-875 Thanks a lot for this guide. I don't know what I'd have done without it. I'd certainly be messing around, tearing my hair out still. I'm building a failover pair of servers that act as NFS storage and also as reverse proxying Apache servers that serve static content and load balance to a number of Tomcat servers. I'd started on the project without coming across this blog, and I'd managed to compile all the various stacks and even get corosync working, but after that the Pacemaker stuff just wouldn't work. I suspect it's because I didn't compile the OpenAIS package before that it didn't work; the Pacemaker site suggests that as corosync is a cut-down version of it, you don't need to. I tried again from scratch using your slackbuilds and managed to get it working. It still took days of messing around with the CIB configuration for it to actually failover. One thing I found is that the CIB I created based on yours failed over when putting the master node into standby, but didn't failover when I simulated a crash. Like you, I also found the documentation to be poor (and sometimes misleading). I never really found a good overview of all the components, and mostly it just gives you example CIB configs and says 'adapt this for your purposes' without explaining all the various bits. The best documentation I found is on the Novell site at: http://www.novell.com/documentation/sles11/book_sleha/?page=/documentation/sles11/book_sleha/data/sec_ha_manual_config_create.html but of course, that doesn't help you compile it all for Slackware. A final thing; you really do need the SuSE checkproc command for the nfs script to work. I found the source code for this at http://ftp.nluug.nl/os/Linux/distr/pardusrepo/sources/killproc-2.11.tar.gz It's part of the killproc package. Once again, thanks for sharing your trials with the rest of us - it's an invaluable aid. Thanks a lot for this guide. I don’t know what I’d have done without it.

I love the shout-out for voting ideas up on the Ideas portal. Glad to hear about your adventures. We did have Linux X64 server support prior to NetBackup 7. You can check out the SCL for yourself if you like http://bit.ly/cWIks7 We are experimenting with ways to make migration easier in the future. Thanks for the write up.
