I have a dual CPU L2000 and have installed the 0.9.3 release of
PA-RISC Linux and dist-upgraded to the latest unstable Debian
packages. I am running kernel 2.4.9-64, but this problem also occurs
with 2.4.17-64-smp and non-smp, and 2.4.18-64-smp and non-smp.
When I attempt to make a software RAID0 array on 3 1Gb partitions on
3 18.2gb internal SCSI disks, I get this error:
hypo:~# mkraid /dev/md0
handling MD device /dev/md0
analyzing super-block
disk 0: /dev/sdb1, 976880kB, raid superblock at 976768kB
disk 1: /dev/sdc1, 976880kB, raid superblock at 976768kB
disk 2: /dev/sdd1, 976880kB, raid superblock at 976768kB
mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
Syslog says:
hypo:~# tail /var/log/syslog
Apr 30 05:36:34 hypo kernel: sys32_ioctl: Unknown cmd fd(3)
cmd(400c0910) arg(00028a44)

Apr 30 05:36:34 hypo kernel: sys32_ioctl: Unknown cmd fd(4)
cmd(80480923) arg(00029390)
/proc/mdstat says:
hypo:~# cat /proc/mdstat
Personalities : [raid0]
read_ahead not set
unused devices: <none>
I've had a look through the archives and found a few posts about
32-bit to 64-bit IOCTLs but nothing seemed to specifically mention
the RAID stuff.
I also had a look in arch/parisc/kernel/ioctl32.c and there were a
couple of lines commented out with comments like "new RAID code is
half merged". Is RAID on 64-bit PA-RISC a work in progress?
Also, I have noticed that the 2nd CPU in the L2000 is always disabled
when I boot with a SMP kernel, errors like SMP: CPU3 is stuck appear
near the start of bootup. (Sorry I don't have any more detail on
these, but I can provide it if needed)
Any ideas/help would be greatly appreciated. I can provide more
details if needed.
Cheers, James
BTW: Great job on the port to PA-RISC :)

Yeah, if you're doing it :-> If you'd like to post a patch for
translating those ioctl calls that would be great! I think proper
translation of the relevent ioctls is all that's needed.

I just wanted to provide confirmation this is only a problem of
the ioctl wrappers missing which are needed by 64-bit kernels.
L2000 requires 64-bit kernel.

Cool. I have sort of brute forced the ioctl things from sparc64 in,
and the kernel compiles, and I will reboot shortly to test it.
Thanks, James

Woohoo! Just rebooted the L2000 and RAID is now working on it :)
How do I go about submitting a patch (sorry, I am a complete newbie
to kernel stuff).
Basically all I have done is copy the RAID section from the sparc64
ioctl32.c into the parisc ioctl32.c file, and fix up the md.h
include.
Just some output:
hypo:/raid# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid5]
read_ahead 1024 sectors
md0 : active raid0 sdd1[2] sdc1[1] sdb1[0]
2930640 blocks 16k chunks
unused devices: <none>
hypo:/raid# df -k
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda4 15458288 848292 13824744 6% /

Yay! Apply for your "I hacked the PA/Linux kernel" badge at the office ;-)

If it's small (say <20k), post it here. If larger, put it on a
website and send a URL.

Cool. That works for us ;-)

grab the cvsrc from
http://cvs.parisc-linux.org/build-tools/cvsrc?rev=1.2&content-type=text/vnd.viewcvs-markup
and drop that in your ~/.cvsrc.
How-to use anonymous CVS is described on http://cvs.parisc-linux.org/
Basically a patch is the "cvs diff" output of all modified files.

Okay, well here's my patch for RAID on 64-bit Linux/PA-RISC. This is
