I have 6 boxes with a client config (see below) across 6 boxes. I am using distribute across 3 replicate pairs. Since I am running xen I need to disable-direct-io and that slows things down quite a bit. My thought was to move the replicate / distribute to the backend server config so that self heal can happen on faster backend rather then frontend client with disable-direct-io. Does this

Lets say you had 4 servers and you wanted to setup replicate and distribute. What methoid would be better: server sdb1 xen0 brick0 xen1 mirror0 xen2 brick1 xen3 mirror1 replicate block0 - brick0 mirror0 replicate block1 - brick1 mirror1 distribute unify - block0 block1 or server sdb1 sdb2 xen0 brick0 mirror3 xen1 brick1 mirror0 xen2 brick2 mirror1 xen3 brick3 mirror2 replicate block0 -

Supermicro X7DWN+, XEON 5410, Centos 5.2, Xen 3.2.1 At what looks like random times network traffic over xen bridge stops working, the only way I found to fix it is a reboot. This sometimes takes 10 min, other times it may be up for 10 days. This happened with default xen that comes with RedHat EL 5.2 as well as a default install of Fedora 8. Any ideas? ><> Nathan Stratton

Trying to get Xen working with Gluster. I understand you need --disable-direct-io-mode, however that cuts my disk I/O from 130 MB/s to only 22 MB/s. Also when I try to use xen with tap:aio, but only get to Creating root device. Red Hat nash version 5.1.19.6 starting Mounting proc filesystem Mounting sysfs filesystem Creating /dev Creating initial device nodes Setting up hotplug. Creating

I am running Xen 3.3.0 and am trying to run a XenEnterprise image. The image has a hda directory with files called chunk-000000000.gz - chunk-000000042.gz and a filed called ova.xml with the following: <appliance version="0.1"> <vm name="VM"> <label> Manager </label> <shortdesc> </shortdesc> <config

Chip Clock HT Cache Bus Speed --------------------------------------------------------- 5080 3.7 GHz YES 2MB 1066 MHz 5160 3.0 GHz NO 4MB 1333 MHz Does the .7 GHz and HT worth more then 4MB cache and higher bus speed? The application is VoIP so there is not a lot of IO so I would not think Bus Speed would matter. I am finding mixed information on HT, some say it is great, others say it

Hello, What is for you the best GlusterFS scenario in using XenServer (i'm not talking about Xen on a linux but XenServer baremetal) for a web farm (Apache-Tomcat) ? I were thinking of using ZFS as the filesystem for the different nodes. The objectives/needs : * A storage cluster with the capacity equal to at least 1 node(assuming all nodes are the same). * being able to lose/take down any

Hello folks, I am running Xen 2.6 under Centos 5.2 installation, and am trying to port Xen migration abilities to Infiniband. But, the InfiniBand drivers do not work under Xen kernel, only under non-Xen kernels. It looks like I need to install some patches to rectify the situation. Has anyone ever worked with Infiniband and Xen and would be able to give me inputs about the same? I would really

Hello, On a xenserver with several (39) domUs, we experience problems with the system clock of the domUs. The clock seems to drift away several seconds up to two minutes from the dom0 clock. We do have set independent_wallclock=0. According to the docs (i.e. http://wiki.xensource.com/xenwiki/InstallationNotes) that way domUs should use the dom0 clock, but apparently that''s not the case.

Hi Karthik, Thank you very much, you made me much more relaxed. Below is getfattr output for a file from all the bricks: root at gv2 ~ # getfattr -d -e hex -m . /data/glusterfs/testset/306/30677af808ad578916f54783904e6342.pack getfattr: Removing leading '/' from absolute path names # file: data/glusterfs/testset/306/30677af808ad578916f54783904e6342.pack

I am looking for a voip provider that provides good rates (below 5 cents/min or unlimited) to UK NCFA numbers. Braodvoice advertises they do unlimited to NCFA but does not have the ability to actually termiate those calls as per the CTO Nathan Stratton, and last he said they dont even have contracts in place to get service provisioned for that. As such I am looking for another provider to take

Hey, Did the heal completed and you still have some entries pending heal? If yes then can you provide the following informations to debug the issue. 1. Which version of gluster you are running 2. gluster volume heal <volname> info summary or gluster volume heal <volname> info 3. getfattr -d -e hex -m . <filepath-on-brick> output of any one of the which is pending heal from all

Hi Karthik, Thank you for your reply. The heal is still undergoing, as the /var/log/glusterfs/glustershd.log keeps growing, and there's a lot of pending entries in the heal info. The gluster version is 3.10.9 and 3.10.10 (the version update in progress). It doesn't have info summary [yet?], and the heal info is way too long to attach here. (It takes more than 20 minutes just to collect

In reading the Xen list there are frequent postings regarding NTP time drift issues for virtualized guests, correct configurations, etc. We have a solution (no cost) for monitoring time drift of hosts for anyone needing to do so or to determine whether their environment is maintaining time synchronization. For etiquette I am not publishing the information to the list mailing. If interested,

Greetings. I''ve reviewed the list archives, particularly the posts from Zakk, on this subject, and found results similar to his. drbd provides a block-drbd script, but with full virtualization, at least on RHEL 5, this does not work; by the time the block script is run, the qemu-dm has already been started. Instead I''ve been simply musing the possibility of keeping the drbd

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

Hi folks, I'm troubled moving an arbiter brick to another server because of I/O load issues.

I am experiencing strange network behavior from several DomU''s. I can ssh from DomU to any host on the local lan/vlan, I can ping those hosts. However when I go to resolve a hostname DNS fails. I have verified that three other DomU''s are exhibiting the same behavior. I have also verified that Dom0 is functioning properly and can resolve hostnames and access hosts outside of the
