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

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, 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.

Hi All, Scenario: I'm trying to install 9i rac on a 2 node cluster on OCFS2 OS: Oracle enterprise linux To my understanding, OCFS2 supports shared home installs which to my knowledge is not only can i have datafile and control files but also clustermanager files and binaries (pretty much everything: no files or executables need to kept local to any nodes). I have one single shared file for

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.

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

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

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

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

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, 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. CAS2/logdir/var/log/syslog.1-6778-Sep 16 20:57:16 CAS2 kernel: [516366.623623] o2net: Connection to node CAS1 (num 1) at 10.172.254.1:7100 has been idle for 30.87 secs, shutting it down.

This fix modifies o2net layer behavior which seems to trigger some DLM race issues during umount/evictions that needs to be fixed as well. I am working on the dlm issues but meanwhile please review this patch. Thanks, --Srini

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
