Fencing a Dell T110 II
I think I know the answer to this question based on all of the research I've done, but figured I'd ask anyway. I needed a couple of servers for an HA cluster, and our "order" guy here ordered me a couple of Dell PowerEdge T110 II. I'd planned on using IPMI to fence these things with, but later found out that this model is only one of two PE servers Dell sells that has a

Recover botched drdb gfs2 setup .
Hi. The short story... Rush job, never done clustered file systems before, vlan didn't support multicast. Thus I ended up with drbd working ok between the two servers but cman / gfs2 not working, resulting in what was meant to be a drbd primary/primary cluster being a primary/secondary cluster until the vlan could be fixed with gfs only mounted on the one server. I got the single server

KVM HA
Hi, I have two KVM hosts (CentOS 7) and would like them to operate as High Availability servers, automatically migrating guests when one of the hosts goes down. My question is: Is this even possible? All the documentation for HA that I've found appears to not do this. Am I missing something? My configuration so fare includes: * SAN Storage Volumes for raw device mappings for guest vms

c6, drbd and file systems
You could also use pacemaker to manage promoting the drbd device and mounting it with a dead master role as a dependency. Are you using anything to automatically promote the send slave already?

scsi3 persistent reservations in cluster storage fencing
I'm interested in the idea of sharing a bunch of SAS JBOD devices between two CentOS servers in an active-standby HA cluster sort of arrangement, and found something about using scsi3 persistent reservations as a fencing method. I'm not finding a lot of specifics about how this works, or how you configure two initiator systems on a SAS chain. I don't have any suitable

ESXi 4.1 and Cluster Fencing
Hi. I'm new to configuring Clustering . The CentOS 5.5 guest machines will be running on ESXi 4.1 . I'm configuring the clustering using "Conga" . I see that there is support for using ESX to do the fencing. The problem I have is that the guest machines are not allowed to have access the "management network" as per security policies. The guest machines don't no

2 node cluster, Heartbeat2, self-fencing
Hello everyone. I am currently working on setting up new servers for my employer. Basically we want two servers, all of them running several VEs (virtual environments, OpenVZ) which can dynamically take over each others job if necessary. Some services will run concurrently on both servers like apache2 (load balancing), so those need concurrent access to specific data. We had a close look at

Unexplained reboots in DRBD82 + OCFS2 setup
We're trying to setup a dual-primary DRBD environment, with a shared disk with either OCFS2 or GFS. The environment is a Centos 5.3 with DRBD82 (but also tried with DRBD83 from testing) . Setting up a single primary disk and running bonnie++ on it works. Setting up a dual-primary disk, only mounting it on one node (ext3) and running bonnie++ works When setting up ocfs2 on the /dev/drbd0
