similar to: iSCSI / GFS shared web server file system

I have a new Dell PowerEdge 2950 running CentOS 5.0 out-of-box and a Dell MD3000i. I am new to iscsi and, with google and included documentation, am having a heck of a time trying to get the RAID volumes I have created on the 3000i to be seen by the OS as usuable drives. I have printed out SMcli and iscsiadm documentation. I have asked on the linux-poweredge at dell.com site, too. Many

Hi, I''ve looked at ZFS for a while now and i''m wondering if it''s possible on a server create a ZFS mirror between two different iSCSI targets (two MD3000i located in two different server rooms). Or is it any setup that you guys recommend for maximal data protection. Thanks, /Thom This message posted from opensolaris.org

We''re setting up ZFS in front of an MD3000i (and attached MD1000 expansion trays). The rule of thumb is to let ZFS manage all of the disks, so we wanted to expose each MD3000i spindle via a JBOD mode of some sort. Unfortunately, it doesn''t look like the MD3000i this (though this[1] post seems to reference an Enhanced JBOD mode....), so we decided to create a whole bunch of

We've been wrestling with this for ... rather longer than I'd care to admit. Host / initiator systems are a number of real and virtualized CentOS 5.5 boxes. Storage arrays / targets are Dell MD3220i storage arrays. CentOS is not a Dell-supported configuration, and we've had little helpful advice from Dell. There's been some amount of FUD in that Dell don't seem to know what

Dear List, I have one last little problem with setting up an cluster. My gfs Mount will hang as soon as I do an iptables restart on one of the nodes.. First, let me describe my setup: - 4 nodes, all running an updated Centos 5.2 installation - 1 Dell MD3000i ISCSI SAN - All nodes are connected by Dell?s Supplied RDAC driver Everything is running stable when the cluster is started (tested

Looking to cluster an FTP server. Right now we do a mix of stuff where we use a few separate servers linked through various hacks, that utilizes VSFTPd heavily for hundreds of television station news websites, where, of course, the current weather maps get uploaded from everywhere, all day, from NOAA and the like. I'd like to move from the current setup to something that's more HA

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

Hi everyone! I have 2 hosts + 1 ISCSI device. I want to create a shared storage repository and both hosts use together. I wont use NFS. prepared sr: xe sr-create host-uuid=xxx content-type=user name-label=NAS1 shared=true type=iscsi device-config:target=xxxx device-config:targetIQN=xxxx hosts see the iscsi device: scsi4 : iSCSI Initiator over TCP/IP scsi 4:0:0:0: Direct-Access NAS

Hi, I have configured two machines for testing gfs filesystems. They are attached to a iscsi device and centos versions are: CentOS release 5.4 (Final) Linux node1.fib.upc.es 2.6.18-164.el5 #1 SMP Thu Sep 3 03:33:56 EDT 2009 i686 i686 i386 GNU/Linux The problem is if I try to mount a gfs partition it hangs.

Hi list, I setup on 2 Xen Dom0s drbd/gfs a logical volume, this works as primary/primary so both DomUs will be able to write on them at the same time. But I dont know how to mount them from my domUs, I can see them with fdisk -l. The partition is /dev/xvdb1 SHould I install gfs on domUs and mount them on each as gfs partitions? [root@p3x0501 ~]# fdisk -l Disk /dev/xvda: 5368 MB, 5368709120

I am considering building a pair of storage servers that will be using CentOS and GFS to share the storage from a Coraid (SATA+Raid) EtherDrive shelf. Has anyone else tried such a setup? Is GFS stable enough to use in a production environment? There is a build of GFS 6.1 at http://rpm.karan.org/el4/csgfs/. Has anyone used this? Is it stable? Will I run into any problems if I use CentOS 3.5

HI, Sorry for repeating same mail ,while composing that mail i mistakenly typed the send button.I am facing problem with my gfs and below is the running setup. My setup Two node Cluster[only to create shared gfs file system] with manual fencing running on centos 4 update 5 for oracle apps. Shared gfs partition are mounted on both the node[active-active] Whenever i type df -h command it

On CentOS 5, the current centosplus kernel doesn't want to play with the kmod-gfs package (because kmod-gfs wants the stock kernel): # yum install kmod-gfs gives me: Transaction Check Error: package kernel-2.6.18-8.1.14.el5.centos.plus (which is newer than kernel-2.6.18-8.1.14.el5) is already installed Should it work, or is there a separate centosplus build that I've not

Hey All, I have a cluster setup and exporting gfs storage everything is working ok(as far as I know anyway). But instead of mounting the gfs storage I want the xen guest to be installed on the shared gfs storage. But with my current setup when I install the domU on the gfs storage it changes it to ext3. Is it possible this way or does the domU have to be on an ext file system?

Are the RPMs for the latest GFS kernel module GFS-kernel-2.6.9-72.2.0.8 to be used with the version 2.6.9-55.0.9.EL available ? I tried to compile the Source RPMs available from the Red Hat site but the modules can't be loaded because of invalid module format arising from version magic issues. The syslog shows: node0 kernel: gfs: version magic '2.6.9-55.0.9.ELsmp SMP 686 REGPARM

Hi all, Since I've got no reply on redhat cluster list, I'm trying here ... I'm testing a rhcs4 cluster with gfs. I noticed some poor performance while tarring data from a gfs volume to a local disk from both nodes at the same time, so I deceided to have a closer look. Here are the bonnie++ results: http://jure.pecar.org/gfs/ I don't know what to think of these ... but I doubt

Hello there! I made Debian, Xen 2.0 and CLUSTER/GFS work together :). I wrote this little tutorial to help you setup yours. Any feedback is welcome, except comments about W3C validation of my code :p Note that I am talking about compiling CLUSTER with your XEN kernel, I don''t explain how to setup a working cluster. You can find how to setup those in official RedHat docs. You will see,

Hi guys, I'm looking at the possibility of running a pair of servers with Dovecot LDA/imap/pop3 using internal drives with DRBD and GFS (or other clustered FS) for the mail storage and ext3 for the root drive. I'm currently using maildrop for delivery and Dovecot imap/pop3 with the stores over NFS. I'm looking for better performance but still keeping the HA element I have now with

Hello All, We are using Dovecot 1.1.3 to serve IMAP on a pair of clustered Postfix servers which share a fiber array via the GFS clustered filesystem. This all works very well for the most part, with the exception that certain operations are so inefficient on GFS that they generate significant I/O load and hurt performance. We are using the Maildir format on disk. We're also using
