[Bug 33269] Re: root filesystem fails to mount (sata_nv module is loaded)

[Kissell]

okay, i had several things to blame when this problem occured...  I was
assuming it was related to the SATA RAID array, because when I unplug
that array it boots just fine.  But, the actual error gives a UUID of
the IDE disk in my system.  The UUID is correct for the boot partition,
/boot/grub/menu.lst and /etc/fstab match, and everything works fine if
don't have the SATA drives plugged in.  But, if I plug in the SATA
drives, then it gets the intramfs prompt and hangs for at least an
actual minute, probably more like three minutes.  After it's done
hanging, it displays a message about md0 being made active.  Then I have
to type anything on the keyboard and hit return and the system will
continue booting normally.

My RAID-6 is made up of SATA disks, twelve 750GB disks, and totals
7501GB.  I previously had to upgrade to mdadm v2.6.7 in hardy to allow
me to grow/expand the array, to add more space without destroying it.
My guess, is that in my particular problem, the system is for some
reason needing the array to be active before it can see the boot
partition.

I did want to fix this, and I had dual-boot with windows on this machine
just in case I needed a windows machine I wanted to have one, even
though I never use it...  and I was reading that wubi seem linked to a
similiar problem, so I did reformat this machine and installed hardy
server 8.04, everything worked fine there, and then i installed the GUI
because i couldn't figure out how to do a dist-upgrade without the gui,
because intrepid is not a LTS release i had to turn it on in the gui,
anyway, then i upgraded to intrepid, and this intramfs problem returned.
So I can say in my instance, it has nothing to do with windows
partitions, and nothing to do with any radical linux software betas i'd
played around with on this machine, it has everything to do with the
machine not being able to initially see the IDE disk if I have this
other 7TB software partition plugged in at boot.

This is very annoying when i need to reboot, and somewhat scary, and i'm
handing over administration of this box soon to a less technical person.
So I hope this information can help someone figure out a solution.  Let
me know if you need me to try something or post some logs.
