Good day, everyone. I have SAN server build with Openfiler OS, with iSCSI mode turned on. I have two nodes, which connect to that server via iSCSI, using one of two active iSCSI partitions. I've installed ocfs2 1.3.3 with kernel 2.6.23.1, configured it, made ocfs2 partition and was successful in mounting it on both nodes. Everything works just fine, I can upload file from one node and

hi, mount -t ocfs2 -o datavolume,nointr -L "oracrsfile" /u02 when i mount linux partation using above command i recieve the following error mount.ocfs2: Invalid argument while mounting /dev/sdd1 on /u02. Check 'dmesg' for more information on this error. thanks in advance zeeshan

Has anyone succesfully setup, and used CentOS as an iSCSI server? I'm trying to setup a server with 4x500GB HDD's, setup in RAID 10 to act as an iSCSI server for a virtualization project, but I can't find a decent howto on how to setup an iSCSI server using CentOS. I would like to setup something like Openfiler, but we also need todo some other stuff that OpenFiler doesn't

Has anybody tried or knows if it is possible to create a MD RAID1 device using networked iSCSI devices like those created using OpenFiler? The idea I'm thinking of here is to use two OpenFiler servers with physical drives in RAID 1, to create iSCSI virtual devices and run CentOS guest VMs off the MD RAID 1 device. Since theoretically, this setup would survive both a single physical drive

hi, i am trying to install oracle rac on fedora core 6 through iscsi. when i try to mount, mount.ocfs2: Invalid argument while mounting /dev/mapper/rac-crs on /mnt/crs.

> Simple, it's only a NAS device, and not really a file server / web > server / data base server as well. Here is something I am currently lokoing at, and wondering if you'd considered it or if anyone here has done it. I've got a bunch of existing hardware - really good IBM stuff that is all installed with CentOS (with a few exceptions). We want to move to virtualization, but

Changelog from V1 to V2: 1. Modify some codes according to Mark's advice. 2. Attach some test statistics in the commit log of patch 3 and in this e-mail also. See below. Hi all, In ocfs2, when we create a fresh file system and create inodes in it, they are contiguous and good for readdir+stat. While if we delete all the inodes and created again, the new inodes will get spread out and that

We have an application that has many processing threads writing more than a billion files ranging from 2KB ? 50KB, with 50% under 8KB (currently there are 700 million files). The files are never deleted or modified ? they are written once, and read infrequently. The files are hashed so that they are evenly distributed across ~1,000,000 subdirectories up to 3 levels deep, with up to 1000 files

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

Hello everyone. I am currently working on setting up new servers for my employer. Basically we want two servers, all of them running several VEs (virtual environments, OpenVZ) which can dynamically take over each others job if necessary. Some services will run concurrently on both servers like apache2 (load balancing), so those need concurrent access to specific data. We had a close look at

Hi, Does OCFS require NAS hardware to run or does normal PC hard disk work? Thanks, Pete -------------- next part -------------- An HTML attachment was scrubbed... URL: http://oss.oracle.com/pipermail/ocfs2-users/attachments/20081219/1bc9110b/attachment.html

I have been a user of OCFS2 for quite some time now (2 years or so) and a user of Oracle RAC for several years as well. My usage of these two is completely independent though, the cluster filesystem is for application level usage (web servers, etc.) only because RAC can manage its own shared storage directly. And that brings me to my observation/question... I keep seeing a lot of messages

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]

I found this from ocfs1.4 document: g) NFS OCFS2 volumes can be exported as NFS volumes. This support is limited to NFS version 3, which translates to Linux kernel version 2.4 or later. Users must mount the NFS volumes on the clients using the nordirplus mount option. This disables the READDIRPLUS RPC call to workaround a bug in NFSD, detailed in the following link:

Hello. I am experimenting with OCFS2 on Suse Linux Enterprise Server 11 Service Pack 1. I am performing various stress tests. My current exercise involves writing to files using a shared-writable mmap() from two nodes. (Each node mmaps and writes to different files; I am not trying to access the same file from multiple nodes.) Both nodes are logging messages like these: [94355.116255]

Does anyone know off hand how to bind iscsi enterprise target to two distinct addresses. Lets say I have a machine that has a bunch of interfaces on it, with different subnets. Rather than have ietd broadcast itself on all interfaces (the default), I would like to limit it to only two interfaces. I have edited the init.d startup script with --address x.x.x.x which works, but I tried using the

Hello, I have an active, balanced webcluster with 2 SLES10SP2 nodes, both running ocfs2 with an iscsi target. The ocfs2 volume is mounted on both nodes. Everything works fine, except sometime the load on both systems go as high as 200, then both systems freeze, only reboot helps to regain control. I noticed that this behaviour does not occur when the cluster is NOT balanced. When the load on both

Is it possible to implement OCFS2 with an iSCSI filesystem that is shared between 5 web servers. Thanks, LDB
