similar to: partition offset/alignment on SAN devices.

Hi guys! I can?t find an answer in google, so my last hope is this mailing list. Story. I have two servers with same arrays. Servers connected by DRBD. I used ocfs2 as file system, also I used NFS4 to access to the ocfs2 drive. I do not have any idea, but the allocated descriptors in /proc/sys/fs/file-nr increasing every time while drive accessed. So after some time allocated descriptions over

OEL 5, OCFS 1.4, using EMC Power Path for multi pathing. I want t mount the OCFS2 file system on the emc power path device. I can mount by UUID, and not have to worry about persistent bindings across nodes. But how do I make sure when it mounts by UUID , that the pwoer path device is used. Any help will be much appreciated. Thanks -- Sridhar Avantsa savantsa at gmail.com -------------- next

I've been using OCFS2 on a 3 way Centos 5.2 Xen cluster for a while now using it to share the VM disk images. In this way I can have live and transparent VM migration. I'd been having intermittent (every 2-3 weeks) incidents where a server would self fence. After configuring netconsole I managed to see that the fencing was due to a heartbeat threshold timeout so I have now increased

Hello list, I want to use shared volumes between severall vm''s and defenetly don''t want to use NFS or Samba! So i have three options: 1. simulated(software-) iscsi 2. GFS 3. OCFS2 What do you suggest and why? Kind regards, Florian ********************************************************************************************** IMPORTANT: The contents of this email and any

Hello! We are planning to migrate our iSCSI installation (LUN based) to one NFS installation (based in images). iSCSI offers great performance, but we have many dom0s and domUs and the management is difficult (many LUNS, many multipath messages, ...). (We are using Debian Wheezy with Xen 4.1.2) I have some questions: -What formats of disk images support Xen? I have not found support for

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

First of all i would like to thanks Timo for the excellent job done in dovecot. We are using it in you prodution server with about 5 millions of emails and it is pretty good, only a performance problens but i guess it is realated to ocfs2 that we are using. So lets begin: We are using dovecot 2.0.6 with maildir in an ocfs2 partiton. It is pretty slow access in peak time, but it is related to

Allison Smith just created a hysterical parody music on hold Parody. Whatever you were doing, stop, and dial this number to listen to it: 360-519-5689. 2 minutes. I just gave her a few ideas, but she took it and ran with it--she chose the audio and did the mix-down and everything. Really funny!! -Karl -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, We are haing some serious issues trying to configure an OCFS2 cluster on 3 SLES 10 SP2 boxes running in VMware ESX 3.0.1. Before I go into any of the detailed errors we are experiencing I first wanted to ask everyone if they have successfully configured this solution? We would be interested to find out what needs to be set at the VMware level (RDM, VMFS, NICS etc) and what needs to be

Hi everyone. Does anyone know why the user-space heartbeat (linux-ha) patches from SuSE / Novell are not commited to the mainline ocfs2 source tree? Or are they? Is there an easy way (which does not break the distros package management) to apply these? Thanks, Christian

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:

Is it possible to create a highly-available OCFS2 cluster (i.e., A storage cluster that mitigates the single point of failure [SPoF] created by storing an OCFS2 volume on a single LUN)? The OCFS2 Project Page makes this claim... > OCFS2 is a general-purpose shared-disk cluster file system for Linux capable of providing both high performance and high availability. ...but without backing-up

Hello All, We're hosting DB1 and DB2 with db_block_size set to 8K, 16K respectively File system creation is done with mkfs.ocfs2 -b 4K -C 32K -N 4 -L LABLE /dev/mapper/xxxx Mount is done with: ocfs2 _netdev,datavolume,nointr 0 0 I'd like to know if we can separate most of the tablespaces on different LUNs, even if they're on the same disk group sometimes, is it

hi all We have an ocfs2 cluster compose of 4 Debian lenny serveurs wich have access to an ISCSI LUN we have create a partition on this Lun and formated this partition as OCFS2. 2 serveurs does mail delivery (SMTP) and the two other are pop/imap servers. The smtp servers use dovecot LDA to deliver to mailboxes. La version de dovecot is 1.2.13, ldirectord balance conexion to the

Hi, I'm new to this list and to the ocfs2 system and to clustering in general (3 strikes?--ack!). I have some problems with my first attempt at configuring an ocfs2 system and need some perspective. My setup is a Compaq Proliant CL380 2 node cluster with a shared storage array. Both nodes are currently running SLES 10. However, I am just trying to get one node working. I have read the

Hello, First of all, i am new at the list and i have several questions about ocfs2 performance. Where i am working i am having huge performance problens with ocfs2. Let me tell my envoriment. 3 Xen VirtualMachines withs ocfs2 mounting an LUN exported over iSCSI. ( acctualy 3 LUNS, 3 ocfs2 clusters ) I am not the one who configured the envoriment, but it is making the performance of my MAIL
