Hi, I have 6 nodes cluster with OCFS2 1.4.2 running on vmware virtual system RedHat 5.2 (2.6.18-128.1.16.el5) 64bit. Out of 6 nodes two nodes alf0 and alf3 reboot automatically, I enabled remote logging for kernel, and here is log. I noticed VM become non-response and suddenly reboots. I am running Alfresco (documents sharing) application all nodes are accessing common share on OCFS.

Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout. It disconnects on net timeout is ok, but it should attempt to reconnect back. This is because sometimes nodes get overloaded enough that the network connection breaks but the disk hb does not. And if we get into that situation, we either fence (unnecessarily) or wait for its disk hb to die (and sometimes hang

Hi All, We have ocfs2 node cluster with oracle 11G RAC running, The node2 got crashed automatically, when i rebooted node one for maintenance. please check the log from node2 , before its got crashed.

Modification from V1 to V2: 1. Use atomic ops instead of spin_lock in timer. 2. Add some comments when querying connect_expired work. These comments are copied form Zach's mail.;) Currently, o2net connects to a node on hb_up and disconnects on hb_down and net timeout.

Hi list, I am experimenting with ocfs2 (rpm package: 1.2.2-0.2), using linux-ha 2.0.8 (all running on a SLES 10 x86-64, rpm packages from linux-ha.org) for the heartbeat. The three nodes are connected on a gigabit switch. From time to time I have problems to unmount a drive, and I have to reboot the whole system to fix the problem. When these lockups occur, I see these messages in

?i, I have a cluster with 5 nodes hosting web application. All web servers save log info into shared access.log file. There is awstats log analyzer on the first node. Sometimes this node fails with the following messages (captured on another server) Apr 20 17:31:16 um-be-2 [145813.022112] o2net: connection to node um-fe-1 (num 1) at 192.168.10.10:7777 has been idle for 30.0 seconds, shutting it

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

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

Hi, we have recently started to use ocfs2 on some RHEL 5.5 servers (ocfs2-1.4.7) Some days ago, two servers sharing an ocfs2 filesystem, and with quite virtual services, stalled, in what it seems on ocfs2 issue. This are the lines in their messages files: =====node heraclito (0)======================================== /Dec 4 09:15:06 heraclito kernel: o2net: connection to node parmenides

Hi, all, As we use OCFS2, the network is not good. When the converting request message can?t send to the another node, there will be a node hangs up which will still waiting for the dlm.

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

Hi, I do have a centos 6.x server which accessed two different iscsistorages for a long time without any trouble. The storage-connection is done by a separate NIC and VLAN. The LAN access is on an other NIC. This weekend something broke and I don't have any clue what might be the problem or what caused it. The storages where mounted RO. In /var/loge/messages there are lot of messages; so

Hey guys, I have a OCFS2 Cluster mounted at 4 xen-server (gentoo). Today I upgraded the xen-kernel for tests at one server (server2) from 2.6.34-xen to 2.6.38-xen-r1. After reboot the server couldn''t mount the ocsfs2 device anymore. ocfs2-tools version: sys-fs/ocfs2-tools-1.4.3 Modules are loaded and /config type configfs and /dlm type ocfs2_dlmfs are mounted. server2 ~ # mount

This patch separates o2net and o2quo from knowing about one another as much as possible. This is the first in a series of patches that will allow userspace cluster interaction. Quorum is separated out first, and will ultimately only be associated with the disk heartbeat as a separate module. To do so, this patch performs the following changes: * o2hb_notify() is added to handle injection of

Hallo, I have two servers and both are connected to external array, each by own SAS connection. I need these servers to work simultaneously with data on array and I think that ocfs2 is suitable for this purpose. One server is P4 Xeon (Gentoo linux, i386, 2.6.22-r2) and second is Opteron (Gentoo linux, x86_64, 2.6.22-r2). Servers are connected by ethernet, adapters are both Intel
