Hello My company is changing server software to CentOS on Dell equipment. At the same time we are expanding our RAID system from standard SCSI to either SATA, or the technology brought forward by Coraid using the AoE protocol. Before we take the final decision I am looking for some real experience with Coraid products on a scale of 30+ disks. We will be using a cluster of four servers with a mix

SCSI-2, iSCSI and > FC/FC-AL are. AoE is not. As I understand it, Coraid will allow multiple machines to mount a volume, it just doesn't handle the synchronization. So you can have more than one

Anyone tried to use ocfs2 on a coraid? So far I've found that I had to crank the heartbeat threshold up. Anything else I should know about? I'm running the ocfs2 version that comes with kernel 2.6.16.7 (is there something more recent I should use?) and ocfs2-tools and ocfs2console both v1.1.5 backported to debian stable. Oh, and a coraid SR1520 with ~6T of space in a single

Hello, Is anyone using zfs over coraid aoe? I was thinking about creating a bunch of single disk lblades and then mirroring or raidz them using zfs. Does anyone have any experiences they would like to share? -- This message posted from opensolaris.org

Hi everyone, This is a strange problem I have been having. I'm not sure where the problem is, so I figured I'd start here. I as having problems with Bacula stopping on 17Gig Volume sizes, so I decided to try to Just dd a 50 gig file. Sure enough, once the file hit 17 gigs dd stopped and spit out an error (pandora bacula)# dd if=/dev/zero of=bigfile bs=1M count=50000 File size

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

Hi, I'm going to set up a new storage for our email users (about 10k). It's a network attached storage (Coraid). In your opinion, what is the best file system for mail server (pop3/imap/webmail) purpose? Thank you

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, I have an XCP 0.5 box running a few DomUs some of the DomU''s data is stored at (clustered lvm volumes on) a Coraid etherdrive box which is connected via an Ethernet cable to a dedicated card of the XCP box, for which in the network config I'' ve specified: MTU=9344: xe network-param-list uuid=.... gives: MTU ( RW): 9344 on the DomUs if I leave the MTU at 1500 (default

Hi, Since few days I noticed very high load on my mailserver (Centos 6.6 64bit, 8 GB RAM, 2 x CPU 3.00GHz I am using Dovecot + Postfix + Roundcube + Nginx. I have about 10000 users. Spool is on network attached storage (Coraid). File system is ext4 (mounted with noatime). Problem appears almost every morning (while load is normal during afternoon). I suspect that this can be related to some

I am in the process of completely overhauling the storage setup here and plan to go to glusterfs. The storage involved is 8x Coraid units, 2x JetStor and a Dell MD3000. The Coraid and JetStor are network connected via ATA over Ethernet & iSCSI. The disks are also being upgraded to 1TB in the process. I do plan to use unify to bring most if not all the storage together. My first

I have an OCFS2 filesystem on a coraid AOE device. It mounts fine, but with heavy I/O the server self fences claiming a write timeout: (16,2):o2hb_write_timeout:164 ERROR: Heartbeat write timeout to device etherd/e0.1p1 after 12000 milliseconds (16,2):o2hb_stop_all_regions:1789 ERROR: stopping heartbeat on all active regions. Kernel panic - not syncing: ocfs2 is very sorry to be fencing this

I''m currently trying to build modules against the kernels created with Xen 3.0.5rc4. This used to not be such a problem, as Xen created a kernel directory and the built in it. Plain Jane, nothing fancy. I''ve noticed that somewhere since I did this (which was as recent as 3.0.4-1) the kernel build now does things a bit different. Apparently there is some sort of

I have one of those installed on CentOS 4.6 with 1TB of storage. I'm sharing it between three servers. I can't say how well it works for multi-TB storage, but it works well enough for me

Hi, I just moved mail spool to a different network storage. Now, several users are complaining about duplicate message that are fetched by their clients (Outlook, Microsoft Outlook). What is the reason?

On Coraids (Inventor of AoE) website, they claim the?r drivers will also work on Solaris. So my question is: Will there be any technical limitations regarding implementation of ZFS and AoE ? If not yet possible, the developers of OpenSolaris might consider this option as a natural step I guess. What do Yo...
