Re: [Ocfs2-users] Help ! OCFS2 unstable on Disparate Hardware
Hello Jorge, I have a mixture of 1.4.7 (EL 5.3) and 1.6.3 (EL 5.7 + UEK) and something as simple as an umount has triggered random Node reboots, even on nodes that have Other OCFS2 mounts not shared by the rebooting nodes. You see the problem I have is that I have disparate hardware and some of these servers are even VM's. Probably this is the source of your instability, you shouldn't mix different versions of the filesystem in the same cluster stack, as it *may* have network protocol incompatibility between the versions. Also you should not mount the same filesystem with different driver versions. The nodes that are fencing while not mounting the ocfs2 is probably due to any oops inside the o2cb (cluster stack) driver that *could be* triggered by the mix of versions and some protocol incompatibility between them. Several documents state that nodes have to be somewhat equal of power and specs and in my case that will never be. Unfortunately for me, I have had several other events of random Fencing that have been unexplained by common checks. i.e. My Network has never been the problem yet one server may see another one go away when all of the other services on that node may be running perfectly fine. I can only surmise that the reason why that may have been is because of an elevated load on the server that starved the Heartbeat process preventing it from sending Network packets to other nodes. My config has about 40 Nodes on it, I have 4 or 5 different shared LUNs out of our SAN and not all servers share all Mounts. meaning only 10 or 12 share one LUN, 8 or 9 share another and 2 or 3 share a third, unfortunately the complexity is such that a server may intersect with some of the servers but not all. perhaps a change in my config to create separate clusters may be the solution but only if a node can be part of multiple clusters: /node: ip_port = ip_address = 172.20.16.151 number = 1 name = txri-oprdracdb-1.tomkinsbp.com cluster = ocfs2-back node: ip_port = ip_address = 172.20.16.152 number = 2 name = txri-oprdracdb-2.tomkinsbp.com cluster = ocfs2-back node: ip_port = ip_address = 10.30.12.172 number = 4 name = txri-util01.tomkinsbp.com cluster = ocfs2-util, ocfs2-back node: ip_port = ip_address = 10.30.12.94 number = 5 name = txri-util02.tomkinsbp.com cluster = ocfs2-util, ocfs2-back cluster: node_count = 2 name = ocfs2-back cluster: node_count = 2 name = ocfs2-util / Is this even Legal, or can it be done some other way ? or is this done based on the Different DOMAINS that are created once a mount is done . Isn't possible. The cluster part does not support the definition of more than one cluster. Take a look at the list archives if you are interested in why there could not be more than one definition. How can I make the cluster more stable ? and Why does a node fence itself on the cluster even if it does Not have any locks on the shared LUN ? It seems to be that the node may be fenceable simply by having the OCFS2 services turned ON, without a mount . is this correct ? Another question I have been having as well is: can the Fencing method be other than Panic or restart ? Can a third party or a Userland event be triggered to recover from what may be construed by the Heartbeat or Network tests as a downed node ? Thanks for any of the help you can give me. The server fence because any driver issued a kernel oops due an unexpected behaviour, so there is no guarantee that the kernel or the driver is still stable when it happens. That's why is recommended that the server should restart in this case. You can disable the automatic fence by setting the sysctl parameter kernel.panic_on_oops # echo 0 /proc/sys/kernel/panic_on_oops To permanently disable the fence you can add (or modify) the fallowing line in your /etc/sysctl.conf kernel.panic_on_oops=0 By doing this, the server will not fence if any of the kernel drivers issue an oops, instead, the driver will probably crash and may render your server unstable or crashed by a kernel panic. Anyway, you should configure a netconsole, so if any of them oops or panic, you still get the error messages and stack traces.

Re: [Ocfs2-users] Help ! OCFS2 unstable on Disparate Hardware
Symmetric clustering works best when the nodes are comparable because all nodes have to work in sync. NFS may be more suitable for your needs.
