Hello everybody, after few weeks of trials I''m in final stage of rolling a new server into our production environment and just came across this problem. Basically I''m getting ''bad block'' messages in Windows 2003 when trying to format a new disk in Windows VM. I''m running CentOS 5.4 with xen3.4.2 installed, tried both with GPLPV and standard qemu drivers, windows x32 and x64 - same result, as soon as newly added virt disk size goes beyond 1024G (or above 262144 extents) I get bad block error in windows system log and formatting fails. The server is DellR710 machine with 146G raid1 SAS (for VMs systems) and 1.8T RAID5(6x500G Near-line SAS disks with 1 hotswap) for backups. Needless to say formatting in Linux of the whole 1.8T vd goes fine (with full e2fsck check then). Any ideas? Is my only option to split it in 2 virt disks?

Correction to my previous post. Actually it seems the problem is related to GPLPV drivers only - I managed to format all free 1.5TB of the disk on a VM running without GPLPV drivers and ''attach'' it to a server with gplpv_2003x64_0.10.0.138.msi<http://www.meadowcourt.org/downloads/gplpv_2003x64_0.10.0.138.msi> installed. That works but I''m kinda worried with running it all in production. Do you guys really use xen-gplpv for virtualizing Windows servers? QEMU performance is pretty much makes it not an option for high load services.

James might be able to help you more. At this point it''d be a good idea to change your subject to include "GPLPV".> That works but I''m kinda worried with running it all in production.

I mostly use it for small stuff though, nothing involving windows cluster or > 1 TB disk -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
