Re: [leaf-user] Help! Problems getting Raid5 to work. Banging my head against the wall!

Charles -- are you familiar with this problem? Your raid guide mentions being able to use raid5 partitions, but this error is stopping me. I've also looked through the software raid-howto and found nothing about this error. I've google'd the error and the only thing I've been able to find says that raid is not supported by my kernal -- but the uname -a says I have the right one. Do I have a raid.lrp that is missing something, or should I be using a different kernal?

Any help would be greatly appreciated.

thanks.

Hi, it's been a very long time since I've posted, but I'm stuck on my raid config. I'm running Dachstein w/the raid-ide kernal:

# uname -a Linux toaster 2.2.19-3-LEAF-RAID #2 Sat Dec 1 17:15:49 CST 2001 i386 unknown

I loaded the raid0,1,5 modules, and raid.lrp. I also have the hdsupp tools: # lrpkg -l Name Version Description ===============-==============-==============================================

root 4.0.6 etc 4.0.1 ramlog 1.1 Creates additinal ramdisks on boot local 4.0.6 Local package. This package does not contain a modules 4.0.6 Modules package. Contains kernel modules and u libz 1.1.4 zlib compression library.

I have the following raid conf file:
raiddev /dev/md0
      raid-level              5
      nr-raid-disks           3
      nr-spare-disks          0
      chunk-size              4
      persistent-superblock   1
      device                  /dev/hdc1
      raid-disk               0
      device                  /dev/hdd1
      raid-disk               1
      device                  /dev/hdd2
      raid-disk               2
Yes, I know, ignore the fact that the 2nd partition sets are on the same
disk -- I'm just trying to see if I can get it to work.  I also tried
doing a straight Raid 1 using the first two partitions in the set above
and get the same error.
When I do my mkraid command, I get the following:
# mkraid /dev/md0
cannot determine md version: No such file or directory
#
What am I missing?
thanks.
