similar to: Shared volume: Software-ISCSI or GFS or OCFS2?

Hello Everyone I work for a University Department that has a high number of Linux Desktop Users. Currently we provide a users home directory via NFS from a file server. Generally it works well for us, but I have been asked to look at our options for expanding the storage we have available. So I thought one of the first things I had better do is consider are there alternatives to the way we

Hello, We need to use iSCSI in some of our domUs. By the moment, iSCSI is not for system filesystem, but for data filesystem. I am wondering what is the best way to use it. Is it better to configure it in dom0 and then attach the device to the domU? Or is it better to configure it directly in the domU? I am thinking that if we configure it in the dom0, then we can''t share that iscsi

We're trying to setup a dual-primary DRBD environment, with a shared disk with either OCFS2 or GFS. The environment is a Centos 5.3 with DRBD82 (but also tried with DRBD83 from testing) . Setting up a single primary disk and running bonnie++ on it works. Setting up a dual-primary disk, only mounting it on one node (ext3) and running bonnie++ works When setting up ocfs2 on the /dev/drbd0

I have a quad core server in which I want to run 4 virtual servers. On this server I have a 1/2 terabyte raid 1 I have split between the 4 members that have the OS on it. I have raid 5 10 terabyte internal storage running on a 3ware 9690a card. I want to share this storage between the servers without partitioning it. Is this possible? -------------- next part -------------- An HTML attachment

Hello Ladies and Gents .. First time poster .. I have been experiencing several issues with unexplained Fencing and silly mount/unmount errors With Version 1.4.7 on UEK (Red Hat Enterprise Linux Server release 5.3) running under kernel 2.6.18-128.el5 With ocfs2console-1.6.3-2.el5,ocfs2-tools-1.6.3-2.el5 & ocfs2-2.6.18-128.el5-1.4.7-1.el5 RPM Packages. You See, the problem is that I was

Hello: I am planning to implement GFS for my university as a summer project. I have 10 servers each with SAN disks attached. I will be reading and writing many files for professor's research projects. Each file can be anywhere from 1k to 120GB (fluid dynamic research images). The 10 servers will be using NIC bonding (1GB/network). So, would GFS be ideal for this? I have been reading a lot

We currently have a MD3000i with an iSCSI LUN shared out to our apache web server. We are going to add another apache web server into the mix using LVS to load balance, however, I am curious how well iSCSI handles file locking and data integrity. I have the iSCSI partition formatted as ext3. Is my setup totally flawed and will ext3 not allow for data integrity with multiple apache hosts

Nick, What are you planning on running over the shared connection? Database, eMail, File Shares? How many users? How much data? What is your I/O profile? I've worked with 'enterprise' storage most of my career either as a consumer, adviser or provider - can't comment on AoE other than to suggest you look at what are the business & technical goals, how they solve it and what

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

Hi, I am trying to configure a two node cluster on SLES10SP2 using user level heartbeat.

Hello all. I would like to canvas some opinions on options for shared storage in a Xen cluster. So far I've experimented with using iSCSI and clvm which mixed success. The primary concern I have with both of these options is that there seems to be no obvious way to ensure exclusive access to the LUN/device to the VM I want to run. On a couple of occasions during my playing I've

I need the community''s opinion on the best way to use my storage SAN to host xen images. The SAN itself is running iSCSI and NFS. My goal is to keep all my xen images on the SAN device, and to be able to easily move images from one host to another as needed while minimizing storage requirements and maximizing performance. What I see are my options: 1) Export a directory through NFS.

Hi I have a applikation (Oracle DB) which writes files with a backslash in names, i.e: Log\GEN_INPUT_BASED_2899.csv not a problem for Unix but Samba present it to Windows users as: L2CYOP~L.CSV Is there any way _in Samba_ to strip this 'Log\' and give back to user the GEN_INPUT_BASED_2899.csv part. Tha appliance (EMC Celerra) I've just migrated data from, was magicaly doing this.

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, we have a medium setup (8000 pop and imap users using almost every available client, 800GB of stored mails using maildir on a Celerra NFS server, with index files on local disks, and procmail for local delivery), being served by a Dell PowerEdge 2850 (2GB RAM and dual P4 Xeon 3,2GHz). Our current not-so-high availability setup is based on a similar server with the same setup and a easy

In a prior message I documented my woes in getting an NFS_ROOT xen going. I haven''t resolved those yet, want to try a different tack at this: If the group were to recommend a path of least resistance to showing migration/live migration, which configuration would it be?

I have heard that EMC might be using a port of Samba for their CIFS protocol. Can anybody support or refute this? Are there any commands that can be issued or any operations that can be performed and sniffed to verify this one way or the other? Thanks, Paul

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
