Hey folks,
I'm using FAI 3.2.14 on my Ubuntu systems (booting the 2.6.24-21
kernel), and it all seems to work, except when I have a hardware RAID
with no existing partition table. When the client PXE boots the
kernel that FAI puts in to the TFTP directory, I get kernel panics,
where the kernel complains that it can't find partition tables on any
of the arrays. I don't have this problem testing in my VM's which
have no hardware RAID. Has anyone else seen this? If it matters, I'm
using setup-storage. I can provide a logfile of the boot process that
I captured via a serial console and minicom, if that would be useful.
But everything looks normal up until it can't find the partition
tables on the arrays and panics.
Thanks,
Ryan
For example, here's what it looks like on my VM with no hardware RAID
(and, incidentally, it also had a partition table on it before being
FAI'ed, because it was a clone of another VM):

And, here's what it looks like on the machine with no pre-existing
partition table AND hardware RAID. This is using the PXE config
generated by fai-chboot.
