I recently experienced a strange issue with software raid1+0 under Xen on a new machine. I was getting corruption in my guest volumes and tons of kernel messages such as: [305044.571962] raid0_make_request bug: can't convert block across chunks or bigger than 64k 14147455 4 The full thread is located at http://marc.info/?t=126672694700001&r=1&w=2 Detailed output at http://pastebin.com/f6a52db74 It appears after speaking with the linux-raid mailing list that this is due a bug which has been fixed but the fix is not included in the dom0 kernel. I'm not sure what sources kernel 2.6.26-2-xen-amd64 is based on, but since xenlinux is still at 2.6.18 I was assuming that this bug would still exist. There are a number of possible dom0 kernel in use. The xen.org 2.6.18-xen tree is still maintained on a bugfix basis. Are you seeing the problem with 2.6.18-xen? I don't know what 2.6.26-2-xen-amd64 is, but I'm guessing from the name it is a Debian kernel. I don't know what its provenance is, but it is not a xen.org supported kernel; if a fix is needed you should file a bug against your distro. Modern Xen kernels are based on 2.6.31.x and 2.6.32.x. See http://wiki.xensource.com/xenwiki/XenParavirtOps and http://wiki.xensource.com/xenwiki/XenDom0Kernels for more details.
