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

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

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 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

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

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

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

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

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

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 understand that all work is going into xen3, but I had wanted to note that aoe (drivers/block/aoe) is giving me trouble on xen 2.0.6 (so we can keep and eye on xen3). Specifically I can''t see nor export AOE devices. As a quick background on AOE, it is not IP (not routable, etc), but works with broadcasts and packets to MAC addresses (see http://www.coraid.com). (for anyone who

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? This is my conf: # dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-71.el6.x86_64 x86_64 CentOS release 6.6 (Final) auth_mechanisms = plain login digest-md5 cram-md5

hello ! i try to use a network technology on one single host, which wasn`t designed for that. to give a short overview of what i`m talking about: AoE is just like a "networked blockdevice" (just like nbd/enbd) - but without tcp/ip. AoE kernel driver is the "client end" (see this like an iSCSI initiator) - and an etherblade storage appliance is the "server end"

Hi people. Im new on Xen and I''m looking in how to do a physical migration on Xen. I know that there is a lot of choices (that is the first problem) My environment is simple: 2 physical servers, each one running one instance of XEN. Each host has 2 gigabit cards. One to talk with the world, other to talk between theirselves. I want to run the every vm on the both hosts, if one fail
