We are running OCFS2 on SLES9 machines using a FC SAN. Without warning both nodes will become unresponsive. Can not access either machine via ssh or terminal (hangs after typing in username). However the machine still responds to pings. This continues until one node is rebooted, at which time the second node resumes normal operations. I am not entirely sure that this is an OCFS2 problem at all

Hi, periodically one of on my two nodes cluster is fenced here are the logs: Jan 14 07:01:44 nvr1-rc kernel: o2net: no longer connected to node nvr2- rc.minint.it (num 0) at 1.1.1.6:7777 Jan 14 07:01:44 nvr1-rc kernel: (21534,1):dlm_do_master_request:1334 ERROR: link to 0 went down!

Hi all, I'm running OCFS2 on two system with OpenSUSE 10.2 connected on fibre channel with a shared storage (HP MSA1500 + HP PROLIANT MSA20). The cluster has two node (web-ha1 and web-ha2), sometimes (1 or 2 times on a month) the OCFS2 stop to work on both system. On the first node I'm getting no error in log files and after a forced shoutdown of the first node on the second I can see

Hello, we've had some serious trouble with a two-node Xen-based OCFS2 cluster. In brief: we had two incidents where one node detects an idle timeout and shuts the other node down which causes the other node and the Dom0 to hang. Both times this could only be resolved by rebooting the whole machine using the built-in IPMI card. All machines (including the other DomUs) run Centos 5.2

Hello everyone, once again. We are running into a problem, which has shown now 2 times, possible 3 (once the systems looked different.) The environment is 6 HP DL360/380 g5 servers with eth0 being the public interface, eth1 and bond0 (eth2 and eth3) used for clusterware and bond0 also used for OCFS2. The bond0 interface is in active/passive mode. There are no network errors counters showing and

Hi, everyone I have some questions with the OCFS2 when using it as vm-store. With Ubuntu 1204, kernel version is 3.2.40, and ocfs2-tools version is 1.6.4. As the network configure change, there are some issues as the log below. Why is there the information of "Node 255 (he) is the Recovery Master for the dead node 255" in the syslog? Why the host ZHJD-VM6 is blocked until it reboot

Hello, We have a four-node RHEL4 RAC cluster running OCFS2 version 1.2.8-2 and the 2.6.9-67.0.4hugemem kernel. The cluster has been really stable since we upgraded to 1.2.8-2 early this year, but this morning, one of the nodes fenced and rebooted itself, and I wonder if anyone could glance at the below remote syslogs and offer an opinion as to why. First, here's the output of

Does anybody knows if is there a certified procedure in to backup a RAC DB 10.2.0.3 based on OCFS2 , via split mirror or snaphots technology ? Using Linux LVM and OCFS2, does anybody knows if is possible to dinamically extend an OCFS filesystem, once the underlying LVM Volume has been extended ? Thanks in advance Riccardo Paganini

Hi list, Something went wrong this morning and we have a node ( #0 ) reboot. Something blocked the NFS access from both nodes, one rebooted and the another we restarted the nfsd and it brought him back. Looking at node #0 - the one that rebooted - logs everything seems normal, but looking at the othere node dmesg's we saw this messages: First the o2net detected that node #0 was dead: (It

Wether the dlm_lock needs to access lvb or not depends on dlm_lock_resource it belongs to. So a new parameter "struct dlm_lock_resource *res" is added to dlm_new_lock() so that we can know if we need to allocate lvb for the dlm_lock. And we have to make the lockres availale for calling dlm_new_lock(). Signed-off-by: Wengang Wang <wen.gang.wang at oracle.com> ---

Greetings ocfs2 folks, A client is experiencing some random deadlock issues within a cluster, wondering if anyone can point us in the right direction. The iSCSI connection seemed to have dropped on one node briefly, ultimately several hours later landing us in a complete deadlock scenario where multiple nodes (Node 7 and Node 8) had to be panic'd (by hand - they didn't ever panic on

I have a relatively new test environment setup that is a little different from your typical scenario. This is my first time using OCFS2, but I believe it should work the way I have it setup. All of this is setup on VMWare virtual hosts. I have two front-end web servers and one backend administrative server. They all share 2 virtual hard drives within VMware (independent, persistent, &

Hi all, I'm playing with virsh, and I succeed to mange easily some KVM nodes. But I have issues to size RAM of openvz guests. virsh set by default the the memory to 256M on each guest instead of that I specify in the XML I have to modify by end the variable PHYSPAGES on each /etc/vz/conf/id_of_my_vz.conf Please follow the XML dump and the steps that I did.
