similar to: LVM+Xen+FreeNAS possible?

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,

Hi all, Has anyone created a Xen cluster to run a hadoop vm cluster?

Hi, folks, I''m attempting to run an e-mail server on Xen. The e-mail system is Novell GroupWise, and it serves about 250 users. The disk volume for the e-mail is on my SAN, and I''ve attached the FC LUN to my Xen host, then used the "phy:/dev..." method to forward the disk through to the domU. I''m running into an issue with high I/O wait on the box (~250%)

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 All, What is the best way to remotely monitor/administer a group of xen domUs across a network? We''re planning to deploy a few H/W servers with paravirtualized domUs. What are the best alternatives? What works and What doesn''t? Share your experiences.

Hi all, I''m a newbie on this list. I''m using xen 3.0.3 on CentOS50. I installed a new flavor of kernel in a domU via a standard RPM, which modified my grub.conf by adding a new entry to boot on the new kernel. When rebooting the domU by pygrub, I didn''t see the new grub entry. I tried to restart xend, with no effect. By googling a little, I understood that kernel

Hi. I''m using Xen on RHEL cluster, and I have strange problems. I gave raw volumes from storage to Xen virtual machines. With windows, I have a problem that nodes don''t see the volume as same one.... for example: clusternode1# clusvcadm -d vm:winxp clusternode1# dd if=/dev/mapper/winxp of=/node1winxp clusternode2# dd if=/dev/mapper/winxp of=/node2winxp clusternode3# dd

Hi. Here is the short version: If dom0 experiences a short (< 120 second) network outage the guests whose disks are on iSCSI LUNs get (seemingly) unrecoverable IO errors. Is it possible to make Xen more resiliant to such problems? And now the full version: We''re testing Xen on iSCSI LUNs. The hardware/software configuration is: * Dom0 and guest OS: SLES10 x86_64 * iSCSI LUN on

Hi All, I''m currently installing RHEL 5.1 with Xen and I want to manage the server using a management console that is equivalent with VMware Console or Web based management.

HI Dom0 is CentOS 5.2, 64-bit, Xen version 3.2.1 and 3.2.2. I got Fiber SAN disk system and 2 servers and i am making shared LUN available to both servers. Then i got multipath layer running on both Dom0s and so Xen is seeing device-mapper file, instead of two /dev/sdX devices, then i have setup Xen domU (HVM Windows 2003) using /dev/mapper/sharedLUN as physical storage to my windows server.

I need to installa a streaming server for live videos and for video on demand. My choice is red5. Do you think I can use a xen virtual machine to run a streaming service? Or it is better not to virtualize? Sorry for my bad english. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hello, I have a small Xen farm of 8 dom0 servers with 64 virtual machines running para-virtualized and this has been working great. Unfortunately, I''ve hit a limit: my iSCSI hardware supports only 512 concurrent connections and so I''m pretty much at the limit. (Wish I would have seen that problem sooner!) Of course, 87% of those connections are idle-- but necessary because I

Good afternoon all. I have an odd problem that has me stumped and I'm hoping someone here may be able to help. Recently I switched from a Gentoo Linux based OS to FreeNAS. The version of Samba running on FreeNAS is 3.5.5 (and was the same under Linux). I mainly use my FreeNAS/Samba box to share MP3 files to an Audiotron. One of the files is the Turtle Beach radio file, radio_tr.txt. When I was

Hi, I''m curious about how you guys deal with big virtualization installations. To this date we only dealt with a small number of VM''s (~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the "storage guy" I find it quite convenient to present to the dom0s one LUN per VM that makes live migration possible but without the cluster file system or cLVM
