similar to: HA Xen on 2 servers!! No NFS, special hardware, DRBD or iSCSI...

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

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"

Hello everybody, I am in the process of setting up a really cool xen serverfarm. Backend storage will be an LVMed AoE-device on top of DRBD. The goal is to have the backend storage completely redundant. Picture: |RAID| |RAID| |DRBD1| <----> |DRBD2| \ / |VMAC| | AoE | |global LVM VG| / | \ |Dom0a| |Dom0b| |Dom0c| | |

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?

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

Dear Devs, Would there be any problem to use nbd (/dev/ndX) devices to gain btrfs-raid across multiple physical hosts across a network? (For a sort of btrfs-drbd! :-) ) Regards, Martin http://en.wikipedia.org/wiki/Network_block_device http://www.drbd.org/ -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org

Hello Everyone, I recently had a question that got no responses about GFS+DRBD clusters for Xen VM storage, but after some consideration (and a lot of Googling) I have a couple of new questions. Basically what we have here are two servers that will each have a RAID-5 array filled up with 5 x 320GB SATA drives, I want to have these as useable file systems on both servers (as they will both be

Dear developer, I am working on a project for my graduate work (diploma), which includes iSCSI and AOE booting. I made some menus using pxelinux and things are working fine with linux, but I have a small problem with windows system which require direct iscsi or aoe access. I have dhcpd.conf setup that it to each first dhcp request handles out pxelinux.0, then I can chooose from that menu which OS

Hi, I have installed and configured ocfs2 as per the given guidelines on two nodes. The output of the service status of o2cb and ocfs2 is as under: Node: rashida1 -------------------------------------------------- [root at rashida1 ~]# service o2cb status Driver for "configfs": Loaded Filesystem "configfs": Mounted Driver for "ocfs2_dlmfs": Loaded Filesystem

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 all, Can anyone pleas tell me what would be best practice to use shared storage with virtual machines, especially when it involved high availability / automated failover between 2 XEN servers? i.e. if I setup 2x identical XEN servers, each with say 16GB RAM, 4x 1GB NIC''s, etc. Then I need the xen domU''s to auto failover between the 2 servers if either goes down (hardware

I tried to create a domain with drbd based disk as the backend "drbd:<resourcename>,..," and I get a "unknown disk type" error. I can spin out a patch if needed, but just wanted to know apriori if this was left out for any specific reason. shriram _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

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?

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

Hi List, i have running xen-3.0.2 and my migration time for DomU from Server A to Server B is about 20sec. The Servers A and B are connected over 1GBit/s Links and the storrage is connected via iSCSI. The iSCSI volumes have a performance about 20-40MByte/s. Servers A is a 2x2GHz Xeon with 4GB Ram and Server B is a 1.8GHz AMD with 2GB Ram. The documentation states about some 60-300msec, so my

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

I am testing several Operating System Streaming products to streams virtual desktops. They always requires pxe boot but xen seems to have a pxe which is not suitable. I got the same problem with kqemu and kvm and I solved it using gpxe. With xen I tried to chainloading gpxe (following gpxe wiki) but hvmloader fails to load it (memory problem?). Any workaround

Hai,   I was just reading : https://www.howtoforge.com/tutorial/ata-over-ethernet-aoe-on-debian-8-jessie/   I was wondering, anyone tried AoE for sysvol, so i dont needs replication anymore. Anyone Pro’s and Con’s ?    Or can anyone tell of sysvol is going to be replicated by samba so we dont need scripts anymore.     Greetz,   Louis
