similar to: Xen issues with Gluster

I had a supermicro server SuperServer 1027R-WRF4+ and a old Dell PowerEdge 2950. In both machines I setup centos 6.5, which is running 3.10.34-11.el6.centos.alt.x86_64. I follow Xen4Cen wiki to setup Xen, I had other servers running Centos 5.x without issues. Now, once I build my vm's dom-u centos 6.5/centos 5.9 both x64, I receive different erros, let me show u the message I receive in my

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 -

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

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

I am having an issue getting a DomU to boot properly. There is never any indication of a stop error or kernel panic, it simply hangs after "Starting crond [ OK ]" and never continues.

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

So I have a problem, I have learned that GlusterFS 2.0.8 will not self heal on open files. This would not be a huge problem, except I am running xen and my files are basically always open. I have been running things for about a week now and I am concerned that when I have a crash I could lose all the new data. Is there a way to see what node GlusterFS is using for a open file and is there a

Hello, i will describe my approach 1) I have downloaded Centos5-64bit xen image from jailtime.org 2) I have created own swap image with 512MB file size 3) I have used same as dom0 kernel 2.6.18-53.1.19.el5xen 4) I have mounted my image file and copied /lib/modules/2.6.18-53.1.19.el5xen 5) I have created custom ramdisk for domU with mkinitrd --with=xennet --preload=xenblk

Ok So I''ve been able to successfully create a CentOS5 virt-install on xen using LVM created partitions. But have many problems trying to install 4.4 (It does not work with virt-install hence you have to try another method). I Created a name, name-tmp, name-swap, name-root paritions. I did mke2fs and mkswap no problem everything is good. I went on further to mount the name-tmp and

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

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, 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.
