...ot; (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" (see this like an iSCSI target) there is a software equivalent to etherblade storage which is called vblade (part of the aoetools project) - or vblade-kernel (another implementation, but done as a kernel module) a very nice article about what AoE is can be found at http://www.linuxjournal.com/comment/reply/8149 what i want to do is nicely described in this bugreport by some other person: http://bugs.d...

...ecifically 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 wants to test or play) In my dom0 (w/ aoe module), I installed aoetools and vblade ( http://aoetools.sourceforge.net ). aoetools are not necessary, but nice. vblade lets you export a block device to the network. I exported an lvm device (worked fine on non xen machine) with: vblade 2 0 eth0 (2 is shelf number and 0 is slot number -- can be anything). If I export from non-xe...

I ran into an interesting/strange issue today. I still don''t understand what happened, but in know what fixed it. I had a situation where I could only see vblade exported devices from OFF the physical machine. It seemed that if the packets went through two ports of the bridge (instead of one port and the real interface) they got "lost". I sniffed around and failed to figure out what was going on. As soon as vblade fired up I started seeing th...

Guys, I have setup my hard disc with 3 partitions: 1- 256MB on /boot; 2- 2GB on / for my dom0 (Debian 5.0) (eth0 default bridge for guests LAN); 3- 498GB exported with vblade-persist to my network (eth1 for the AoE protocol). On dom0 hypervisor01: vblade-persist setup 0 0 eth1 /dev/sda3 vblade-persist start all How to create a CVLM VG with /dev/etherd/e0.0 on each of my dom0s? Including the hypervisor01! I do not want to use GFS2/OCFS2 on top of CLVM, since I just...

Dear all: I''m sorry I crossmail. I try setup aoe-vblade server on netbsd 5.0.2(domU) and I try to do some stress test with for i in {65536}; do dd if=/dev/zero of=/dev/etherd/e?.? bs=4K;done on a Linux box Two Xen dom0 configurations I use: 1. 32bits SuSE Enterprise Linux 11sp1 2.6.32.12-0.7-xen with 32bits Xen 4.0.0_21091_04-0.2.6 2. 64bits Gentoo 2.6....

I''ve installed debian lenny amd64, it is frozen now. I''ve install kernel for xen support but it doesn''t start. It says "you need to load kernel first" but I''ve installed all the packages concerning xen, also packages related to the kernel. Perhaps lenny doesn''t support xen anymore? Any solution?

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

Hi people... Here we use Xen 4 with Debian Lenny... We''re using kernel 2.6.31.13 pvops... As a storage system, we use AoE devices... So, we installed VM''s on AoE partition... The "NAS" server is a Intel based baremetal with SATA hard disc... However, sometime I feeling that VM''s is so slow... Also, all VM has GPLPV drivers installed... So, I am thing about

Hi, We are planning to have LVM being used over a network of 3 h/w machines(500 GB Disk each) Each hardware machine will have 2-3 domUs. Can we store these domUs as a Logical Volumes stored across Network of these 3 machines? Can one DomU exceed the 500 GB (physical drive size) and store say 1 TB of data across the networked Physical Volumes? Has anyone done this before? Thanks and regards,

Hello, We are going to buy some NFS storage for 6-8 VMs on a single host, but want to expand to a second host. What storage recommendations would you give if you have between 2000 and 5000 USD? How about nexenta? what hardware would you use? any vendor? Experiences with openfiler and opennas? Thanks for the responses. Daniel -- +-=====---------------------------+ |

...Two are Dom0 OS and swap, two unformatted. * Connect the intra-node NICs with a crossover/switch/hub (Didja know that gigabit NICs are auto-MDIX? No crossover needed!) * Configure the intra-node IPs to something like 10.0.0.1 and 10.0.0.2 or 192.168... * Install Xen * Install ATA over Ethernet and VBlade in Dom0 * Node1: vblade 0 1 /dev/hda3 eth1 # This is one of the unformatted partitions * Node2: vblade 0 2 /dev/hda4 eth1 # The other # Or use vbladed but I don''t know how yet * modprobe aoe on each node * Install LVM on both nodes (in Dom0) * Create two volume groups on each node: Nod...

...permits I can try to reproduce it on latest Xen builds. The domU''s disks look like this: ''phy:/dev/etherd/e0.4,sda1,w'' ''phy:/dev/etherd/e1.4,sda2,w'' Inside the domU, sda1 is treated as root device and sda2 is treated as swap. The AOE setup involves, vblade servers running on the server machine that exports some disks over AOE. The dom0 instance in question is a client to this AOE server. It has ''aoe'' module loaded into it and the aoe-tools version is 10. The stack trace of the crash is as follows: Unable to handle kernel NULL poin...

Hi. We've been using PXELINUX for years, to kick off OS installations (floppy images) and booting assorted tools. The addition of ISO support in memdisk opened up some new alternatives that we also use, e.g. booting WinPE ISO images over PXE. Today I downloaded a BIOS for a HP EliteBook 8440p and discovered that the BIOS file is 3 MB. I could probably squeeze it onto a 2.88 MB floppy image

I want to thank everyone who has provided insight into my thread about clustering MySql. I kind of just sat back and watched it develop. I learned a lot from it all. I have been reading all of the documentation on clustering provided by Centos/Red Hat, and find I travel in circles. I read one chapter and answer a self-imposed question but I end up asking myself another. What I really want to
