Hello, I'm thinking about some HW redundancy of our server. I'd like to have second machine (slave) and when the first one (master) is down, the second should take place and provide all services. But the HW is bit limited now. I have one physical machine (tower server) without STONITH and if possible, I'd like to use as a slave virtual machine (in same network). So the best solution might be just keep one machine, good backups and in case of HW crash restore onto new HW... Richard Brown pointed me to Pacemaker (links are below). I have some doubts about possibility to use it in my case and I'd like to hear if someone is using it and preferably has possible experience with those tools. :-) https://www.youtube.com/watch?v=e9fElUiCdcY https://en.wikipedia.org/wiki/STONITH https://software.opensuse.org/package/ha-cluster-bootstrap https://www.suse.com/documentation/sle-ha-12/ http://clusterlabs.org/ http://drbd.linbit.com/ http://www.linux-ha.org/wiki/Main_Page Sincerely, V.
Hi We made one for a file server using our teacher's instructions: http://linuxcostablanca.blogspot.com.es/2014/07/samba4-cluster-for-ad-drbd-o cfs2-ctdb.html It's time consuming but fun. We had a competition. The record on hardware is start to finish in 3 hours. Tell us if you have a go yourself. HTH
This looks very nice. Thank You for the reports. Now I must go to study more and think about it little bit before the action. Yours, V. -- Vojtěch Zeisek Komunita openSUSE GNU/Linuxu Community of the openSUSE GNU/Linux http://www.opensuse.org/ http://trapa.cz/
