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

hi to the list, Hello everyone, I am new in the world of pxe booting and i try to use AOE to boot my linux debian lenny machines. I install the linux like this: parted -s /dev/etherd/e10.1 mklabel gpt parted -s /dev/etherd/e10.1 mklabel gpt parted -s /dev/etherd/e10.1 mkpart primary ext3 17408B 314590207B parted -s /dev/etherd/e10.1 mkpart primary ext3 314590208B 3535815679B parted -s

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, I have noticed I have the following in my dmesg: [319769.043163] nbd: registered device at major 43 [319769.104176] nbd11: unknown partition table [319769.130273] device fsid c2598ff2-1e3e-4edf-ab19-1f7ab41b0160 devid 1 transid 125743 /dev/nbd11 [319769.130522] btrfs: force lzo compression [319769.130528] btrfs: disk space caching is enabled [319802.926547] Btrfs detected SSD devices,

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 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 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| | |

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"

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.

library(xts) library(TTR) ndx = getYahooData("^NDX") aa = ndx$Close bb = aggregate(aa, as.yearweek, tail, 1) The last operation takes forever, and then the bb dates are messed up. The following produces the desired result: time(aa) = as.Date(time(aa)) bb = aggregate(aa, as.yearweek, tail, 1) The index of ndx and aa is of POSIXct (as reported by is(time(ndx))) , which apparently

My two lists look like below Need an R code example that combines the two. l_one "key" 2 1 2 l_two "ndx", "descr" 1, "this" 2, "that" 3, "other" 4, "finis" My goal is a new list that looks like below. ndx descr 2 that 1 this 2 that Thanks, Jim

I''ve been brainstorming... I want to create a 2-node HA active/active cluster (In other words I want to run a handful of DomUs on one node and a handful on another). In the event of a failure I want all DomUs to fail over to the other node and start working immediately. I want absolutely no single-points-of-failure. I want to do it with free software and no special hardware. I want

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

CC llvm-dev ---------- Forwarded message ---------- Hello Duncan The size of ARM binaries created by clang has increased after r236642. Would you be able to find some time to look at my findings and share your thoughts about the problem, please? r236642 prevents emitting of temp label names into object files to save memory. This is fine, the label names do not appear in the resulting binaries.

I noticed that my server has a lot ca. 1000x auth failure from different alocated in China / Romania and Netherlands per day since 3 days It looks to me like somebody was trying to get into server by guessing my password by brute force. what would be the best to stop this attack and how? the server running apache mysql and ftp PORT STATE SERVICE 21/tcp open ftp 80/tcp open http 443/tcp

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

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

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 -- +-=====---------------------------+ |
