similar to: OCFS2 + iscsi: another node is heartbeating in our slot (over scst)

Greetings, Last night I manually unpresented and deleted a LUN (a SAN snapshot) that was presented to one node in a four node RAC environment running OCFS2 v1.4.1-1. The system then rebooted with the following error: Oct 21 16:45:34 ausracdb03 kernel: (27,1):o2hb_write_timeout:166 ERROR: Heartbeat write timeout to device dm-24 after 120000 milliseconds Oct 21 16:45:34 ausracdb03 kernel:

All, We are having some problems getting OCFS2 to run, we are using kernel 2.6.15 with OCFS2 1.2.1. Compiling the OCFS2 sources went fine and all modules load perfectly. However, we can only mount the OCFS2 volume on one machine at a time, when we try to mount the volume on the 2 other machines we get an error stating that another node is heartbeating in our slot. When we mount the volume

I think I might have miss understood where it is failing, has this file been added to the DB on the web site or does it fail when you try to onfigure this?

Hi everyone; I have a problem on my 10 nodes cluster with ocfs2 1.2.9 and the OS is RHEL 4.7 AS. 9 nodes can start o2cb service and mount san disks on startup however one node can not do that. My cluster configuration is : node: ip_port = 7777 ip_address = 192.168.5.1 number = 0 name = fa01 cluster = ocfs2 node: ip_port =

Our cluster is has recently been logging messages like this: Apr 18 08:05:39 lv2 kernel: (26235,1):o2hb_do_disk_heartbeat:776 ERROR: Device "blk_shared": another node is heartbeating in our slot! where blk_shared is the name of the shared disk that we have ocfs2 mounted on. Can someone tell me what this means?

Hello, I have one cluster drbd8+ocfs2. If I mount ocfs2 partition on node1 it's work but when I mount partition on node 2 I receive in /var/log/messages this -Mar 5 18:10:04 suse4 kernel: (2857,0):o2hb_do_disk_heartbeat:665 ERROR: Device "drbd1": another node is heartbeating in our slot! -Mar 5 18:10:04 suse4 kernel: WARNING: at include/asm/dma-mapping.h:44 dma_map_sg() -Mar 5

All, This is hopefully the final drop of the patches for adding global heartbeat to the o2cb stack. The diff from the previous set is here: http://oss.oracle.com/~smushran/global-hb-diff-2010-10-07 Implemented most of the suggestions provided by Joel and Wengang. The most important one was to activate the feature only at the end, Also, got mostly a clean run with checkpatch.pl. Sunil

Hi, I'm pretty new to ocfs2 and a bit stuck. I have two Debian/Squeeze (testing) machines accessing an ocfs2 filesystem over aoe. The filesystem sits on an lvm2 volume, but I guess that is irrelevant. Even when mostly idle, everything accessing the cluster sometimes hangs for about 20 seconds. This happens rather frequently, say every 5 minutes, but the interval seems irregular while the

Dear Sirs and Madams, I run a small visual effects production company, Hammerhead Productions. We'd like to have an easily extensible inexpensive relatively high-performance storage network using open-source components. I was hoping that OCFS2 would be that system. I have a half-dozen 2 TB fileservers I'd like the rest of the network to see as a single 12 TB disk, with the aggregate

Hi, I''m curious about how you guys deal with big virtualization installations. To this date we only dealt with a small number of VM''s (~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the "storage guy" I find it quite convenient to present to the dom0s one LUN per VM that makes live migration possible but without the cluster file system or cLVM

I was looking up on iSCSI in preparation and became aware that there are different iSCSI software/drivers/whatever-is-the-correct-term available. e.g. IET http://iscsitarget.sourceforge.net/ SCST http://scst.sourceforge.net/ STGT http://stgt.berlios.de/ LIO http://linux-iscsi.org/ Based on what I can see, it seems to be STGT because the site provides a link to Redhat advisory which seems to

Hi, hope the week has started out well for everyone. This report may be in the FWIW department since there may be a fundamental reason why this doesn''t work. We elected to report this to the Xen community since we thought any behavior which corrupted disk images needed to at least be reported. We are maintaining the Xen-SAN release which provides hotplug functionality to allow Xen

Hello, I hope to be in the right list. my question is the following. I can''t seem to get multipathing configure on XCP 1.6. In XenCenter I was able to enable "Multipath" however, in the LUN under general tab I see " multipath 1 of 1 active", the the CLI I do the following command xe --m node session it list only one session. Can someone help me please? Thanks in

Hello all, I got some severe iscsi connection loss on my dom0 (Gentoo 2.6.20-xen-r6, xen 3.1.1). Happening several times a day. open-iscsi version is 2.0.865.12.

I''m trying to do nested XEN to give some of my colleagues a play area to work in, and it seems to work - but not quite. I can build the nested environment (using OVM, and I have to step back to OVM3.2.2 to allow me to do PCI passthrough), but as soon as I start up a VM with a phys device passed through, the first layer loses all connectivity to the SAN.
