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

Hi Xen-Users! I ask for the infiniband support of the xen hypervisor as describet in the following papers http://www.openfabrics.org/archives/spring2007sonoma/Monday%20April%2030/Xiong%20OFA-Sonoma-2007-04-30-SoftIB.ppt and http://www.*xen*.org/files/*Xen*_RDMA_Voltaire_YHaviv.pdf The papers read that a direct infiniband support is possible to circumvent the dom0 to access infiniband devices

Hello everyone, We're currently working with using libvirt as an abstract API to make our dealings with other hypervisors far easier and faster, however, we have our own storage API that connects/disconnects and makes LUNs available over iSCSI with iSER. We would have loved to use a storage pool however our system implements a one target per LUN/VDI, therefore, we'd have to create a pool

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?

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, I'm building a cluster containing two nodes with seperate common storage server. On storage server i have volume with ocfs2 fs which is sharing this volume via iscsi target. When node connected to the target i can local mount volume on node and using it. Unfortunately. on storage server ocfs2 logged to dmesg: Oct 19 22:21:02 storage kernel: [ 1510.424144]

Hi all, I read the FAQ, especially the questions 75-84 about Quorum and Fencing. I want to use OCFS2 with Heartbeat V2 with heartbeat_mode 'user'. What I missed in the FAQ is a explanation of what role in the whole OCFS system is taken by HAv2 (or other Cluster software) when using heartbeat_mode 'user'. 1) When is disk heartbeating started? (Mount of device?) 2) When is

Linus, et al, Here are the ocfs2 changes for 2.6.37. There are three major additions. Tao Ma has added readahead to our CoW operations. Sunil Mushran has added a global heartbeat mode, allowing one device heartbeat to support multiple ocfs2 mounts. Finally, Patrick J. LoPresti has done the final work to enable ocfs2 mounts on devices larger than 16TB. The ocfs2 disk format has always

Hi, i have a debian Etch x86_64 with a xen 3.1 on a kernel 2.6.18-xen. I have some DomU with Debian Etch.

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

Hi, I read at least 100 different documentations during the last week and didn't get it. So I decided to ask the list for help :) Unfortunately we have to move to a Windows 2008 Server ADS in our company as this is required for some other projects. But we want to keep our nice 5+ samba-server providing fast 50TB+ of storage. So we have to find a way to nicely integrate the storage with the

Hello, I already did the trick with "gameoverlayrenderer.dll" but game still isn't launching.

Hi. I'm pretty new to ocfs2 and clusters. I'm trying to make ocfs2 running over a drbd device. I know it's not the best solution but for now i must deal with this. I set up drbd and work perfectly. I set up ocfs and i'm not able to make it to work. /etc/init.d/o2cb status: Module "configfs": Loaded Filesystem "configfs": Mounted Module

I've run into a problem mounting an OCFS2 filesystem on a DRBD device. I think it's the same one discussed at http://lists.linbit.com/pipermail/drbd-user/2007-April/006681.html When I try to mount the filesystem I get a ocfs2_hb_ctl: I/O error: [root at node-6A ~]# mount -t ocfs2 /dev/drbd2 /cshare ocfs2_hb_ctl: I/O error on channel while starting heartbeat mount.ocfs2: Error when

Hi Kalever! First of all, I really appreciate your test results for block-store(https://github.com/pkalever/iozone_results_gluster/tree/master/block-store) :-) My teammate and I tested block-store(glfs backstore with tcmu-runner) but we have met a problem of performance. We tested some cases with one server that has RDMA volume and one client that is connected to same RDMA network. two

This patch removes disk heartbeat's modularity which makes it the default. Without this patch, userspace changes are required. This patch is not intended for permanent application, just to make it easier for users not interested in testing the userspace clustering implementation to use ocfs2. In order to switch to user clustering, use "o2cb offline" to shut down the cluster,

Hi, OCFS2 document is well documented that it is best practice to isolate the network heartbeat from other traffic. Question: Is it also best practice to isolate the cluster/ocfs2 heartbeat? Please also can you explain why or why not. Regards, Vijay -------------- next part -------------- An HTML attachment was scrubbed... URL:
