Hi I've had my OpenSuse 11.2 box booting from /boot-on-RAID1 + everything+else-on-RAID10 for awhile now with no issues. I recently started experimenting with virtualized servers using Xen. Piecing together a bunch of disjointed advice/instructions, I've set up a Guest as a server that I want to use as a RAID-ed NAS. In the Guest/NAS the NAS's "/", swap & boot are all raw devices passed from the Xen Host. For the NAS storage, I have a Passed-through SATA/JBD pci-card that I've connected external drives to. I can boot the Guest, see the PCI card, create a RAID-10 array across those external drives, create & mount LVMs with FSs on them, and reqd/write ok. In other words, everything works just as expected. Except, after rebooting the Guest, the raid array is not started. I can re-assemble it, and rescan/mount the vols on it etc, but can't get the setup to 'stick' across reboot. :-/ This is what I've stored for auto-assembly, cat /etc/mdadm DEVICE /dev/sd[abcd]1 ARRAY /dev/md0 metadata=1.01 name=TESTNAS:0 UUID=b23... and, from the NAS Guest's logs, cat boot.msg | grep -i raid <6>[ 20.614724] md: raid0 personality registered for level 0 <6>[ 20.618933] md: raid1 personality registered for level 1 <4>[ 20.711986] raid6: int64x1 2386 MB/s <4>[ 20.779991] raid6: int64x2 3375 MB/s <4>[ 20.847994] raid6: int64x4 2456 MB/s <4>[ 20.915984] raid6: int64x8 2201 MB/s <4>[ 20.983976] raid6: sse2x1 3581 MB/s <4>[ 21.051979] raid6: sse2x2 5624 MB/s <4>[ 21.119978] raid6: sse2x4 6276 MB/s <4>[ 21.120691] raid6: using algorithm sse2x4 (6276 MB/s) <6>[ 21.123798] md: raid6 personality registered for level 6 <6>[ 21.124550] md: raid5 personality registered for level 5 <6>[ 21.125245] md: raid4 personality registered for level 4 <6>[ 21.129319] md: raid10 personality registered for level 10 <notice -- Dec 16 07:34:54.215943000> service boot.device-mapper done<notice -- Dec 16 07:34:54.216238000> service boot.dmraid startWaiting for udev to settle...

I basically followed the same procedures that work flawlessly for me for my non-virtualized box. :-/ Any suggestions as to what I need to do to get the RAID-10 recognized/built @ boot of the Xen Guest? I have a nagging suspicion that since this RAID array does not contain "/" or "root" it's not being 'looked for' ... but nothing to back that up, yet.
