Hi everyone !
I've setted up a Xen server with kernel 2.6.18-r12 with 2 SATAII disks
of 750Go and with the following partitions scheme :
dom0 ~ # sfdisk -l
Disk /dev/sda: 91201 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start End #cyls #blocks Id System
/dev/sda1 * 0+ 64 65- 522081 fd Linux raid autodetect
/dev/sda2 65 586 522 4192965 fd Linux raid autodetect
/dev/sda3 587 847 261 2096482+ 82 Linux swap / Solaris
/dev/sda4 848 91200 90353 725760472+ fd Linux raid autodetect
Disk /dev/sdb: 91201 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start End #cyls #blocks Id System
/dev/sdb1 0+ 64 65- 522081 fd Linux raid autodetect
/dev/sdb2 65 586 522 4192965 fd Linux raid autodetect
/dev/sdb3 587 847 261 2096482+ 82 Linux swap / Solaris
/dev/sdb4 848 91200 90353 725760472+ fd Linux raid autodetect
dom0 ~ # cat /proc/mdstat
Personalities : [raid0] [raid1]
md1 : active raid1 sdb1[1] sda1[0]
521984 blocks [2/2] [UU]

8385792 blocks 64k chunks
md3 : active raid0 sdb4[1] sda4[0]
1451520768 blocks 64k chunks
dom0 ~ # pvdisplay
File descriptor 3 left open
--- Physical volume ---
PV Name /dev/md3
VG Name vg
PV Size 1,35 TB / not usable 768,00 KB
Allocatable yes
PE Size (KByte) 4096

Free PE 271815
Allocated PE 82560
PV UUID tJg59C-SN1z-SkYX-Qs5H-1TXV-ynNd-HhGTOZ
unused devices: <none>
I've created some guests using LVM logiccal volumes on /dev/md3 and
formatted with XFS filesystem. Sometimes, i've this messages in dmesg on
dom0 :
raid0_make_request bug: can't convert block across chunks or bigger than 64k
After that bugs, there is many Input/Output errors in the guest, and so
broke his gentoo installation so make me impossible to read the guest
system logs. Any help would be greatly appreciated as this server
actually host my primary DNS server and so i can't reinstall it from
scratch.
Many thanks in advance.
Xavier
