Description Alan Cox 2004-09-27 10:57:18 EDT

Description of problem:

Generic AMD64 box, single SATA disk, installed with FC2, updated to FC3

Expected results:
Quiet boot

Additional info:
During the hardware init stage it says something like
RAID_AUTORUN Error 19

Comment 1 Bill Nottingham 2004-09-28 23:21:53 EDT

This error is from nash.

Comment 2 Jeremy Katz 2004-09-29 11:31:05 EDT

Which is ENODEV.  Bill -- what's the "raidautorun /dev/md0" sitting on
line 219 of rc.sysinit there for?

Comment 3 Bill Nottingham 2004-09-29 16:08:29 EDT

To start up any automatic raid arrays after loading all storage
adapters. It's really hard to conditionalize on the presence of an
array at that point.

Note that running 'echo "raidautorun /dev/md0" | nash --quiet' on the
commandline doesn't produce this error for me.

Comment 4 Jeremy Katz 2004-09-29 16:45:26 EDT

Alan -- what version of udev do you have installed?  Stock test2 or a
later one?

Comment 5 Alan Cox 2004-09-29 17:18:25 EDT

Stock test2 - still battling overloaded mirror sites to get to current

Comment 6 Alan Cox 2004-10-22 08:38:25 EDT

Still present and I dont understand why it's assigned to mkinitrd. If
I build a custom kernel with no initrd it -still- does this.

Comment 7 Bill Nottingham 2004-10-22 23:58:44 EDT

nash produces the error, and it's in mkinitrd. It's coming from the
call to nash in rc.sysinit, but it's not real obvious why, as I can't
reproduce it.

If you run:

echo "raidautorun /dev/md0" | nash --quiet

post-boot, does it print the error?

If so, an strace of the nash end would be helpful.

Are there any AVC messages on bootup?

Comment 8 Alan Cox 2004-10-23 08:44:57 EDT

Post boot it does print the error if I do this.

The strace is tiny - 
brk(), brk(), getppid(), getppid() then

read(0, "raidauto...", 32767) = 21
access("/dev/md0", F_OK) = 0
open("/dev/md0", O_RDWR) = 3
ioctl(3, 0x914, 0) = -1 ENODEV
fstat(1,  ... } = 0
mmap(NULL .. [memory alloc])
write(1, "raidautorun: RAID_AUTORUN failed...,
close(3)
close(0)
munmap([memory free])
exit_group

No AVC

Comment 9 Jeremy Katz 2004-10-24 17:50:28 EDT

What is the major/minor of your /dev/md0?

Comment 10 Alan Cox 2004-10-25 16:59:16 EDT

9, 0

Comment 11 Jeremy Katz 2004-10-26 08:50:26 EDT

Wait -- custom kernel?  Does your custom kernel not have RAID built
in?  If so, that's why it's happening.

Comment 12 Alan Cox 2004-10-26 09:29:19 EDT

Doh sorry - yes it is a custom kernel the RH kernel doesnt boot on
that box (known fixed issue). It has raid modular. 

Does that mean it needs closing with "Alan is an idiot" ?

Comment 13 Jeremy Katz 2004-10-26 09:41:03 EDT

Yeah, base RAID needs to be built-in so that we can do raid autorun.

Comment 14 Jon Smirl 2004-11-09 23:40:53 EST

I just went through this exact same problem. Is there some reason
mkinitrd can't include the md module on the boot disk and have nash
modprobe it before raidautorun? It has no problem loading the raid1
module.
