raid on ultra1

raid on ultra1

[Fausto Saporito]

Hello all,

I compiled and booted with new kernel 2.2.0pre4
Is seems all ok, but I have a complete failure with mkraid, either
0.50beta10 either 0.90 version.
RAID support is loaded as module.

My /etc/raid5.conf is

# Sample raid-5 configuration
raiddev                 /dev/md0
raid-level              5
nr-raid-disks           3
chunk-size              32

parity-algorithm        left-symmetric
#parity-algorithm       right-asymmetric
#parity-algorithm       right-symmetric

# Spare disks for hot reconstruction
#nr-spare-disks         0

device                  /dev/sdd4
raid-disk               0

device                  /dev/sde4
raid-disk               1

device                  /dev/sdf4
raid-disk               2

when I run mkraid /dev/md0 I have

The problem is that you have applied the raid patch which is definitely
broken for sparc64. I'll look into it in the next few days and send fixes to
the patch to the maintainers. If it were part of standard kernel, such
problem would not exist.

Cheers,
