I have a problem with raid-0 and reiserfs in linux-2.4.21-pre3-ac5 on Debian/Testing.

When I create two raid-0 partitions with this script:

umount /dev/md0
umount /dev/md1
raidstop /dev/md0
raidstop /dev/md1
dd if=/dev/zero of=/dev/hdi bs=512 count=1
dd if=/dev/zero of=/dev/hdk bs=512 count=1
fdisk /dev/hdi < /root/fdisk.in
fdisk /dev/hdk < /root/fdisk.in
mkraid --really-force /dev/md0
mkraid --really-force /dev/md1
yes | mkreiserfs /dev/md0
yes | mkreiserfs /dev/md

with fdisk.in like this:

n
p
1

140000
t
fd
n
p
2

t
2
fd
w
p
q

and the partitions like this:

Disk /dev/hdi: 80.0 GB, 80026361856 bytes
16 heads, 63 sectors/track, 155061 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hdi1             1    140000  70559968+  fd  Linux raid autodetect
/dev/hdi2        140001    155061   7590744   fd  Linux raid autodetect

Disk /dev/hdk: 80.0 GB, 80026361856 bytes
16 heads, 63 sectors/track, 155061 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hdk1             1    140000  70559968+  fd  Linux raid autodetect
/dev/hdk2        140001    155061   7590744   fd  Linux raid autodetect

I can mount both /dev/md0 and /dev/md1 without any trouble.

After a reboot, I see this:

:mount /dev/md1 /space6
reiserfs: checking transaction log (device 09:01) ...
Using r5 hash to sort names
ReiserFS version 3.6.25
:mount /dev/md0 /space5
FAT: bogus logical sector size 0
VFS: Can't find a valid FAT filesystem on dev 09:00.
mount: you must specify the filesystem type
:mount -t reiserfs /dev/md0 /space5
read_super_block: can't find a reiserfs filesystem on (dev 09:00, block 128, size 512)
read_super_block: can't find a reiserfs filesystem on (dev 09:00, block 16, size 512)
mount: wrong fs type, bad option, bad superblock on /dev/md0,
or too many mounted file systems
:r /proc/mdstat

Personalities : [raid0]
read_ahead 1024 sectors
md1 : active raid0 hdi1[0] hdk1[1]

      141119744 blocks 64k chunks

md0 : active raid0 hdi[0] hdk[1]

      156301312 blocks 64k chunks

unused devices: <none>

I searched google (www/usenet) and didn't find any hints. I'm not mounting the partitions from fstab, so the raid process is started at the correct time.

Can anybody point me to the error I'm making?

Thanks,
Jurriaan

meant to do raidstart here ?

I was switching these disks around on a number of computers, and altering partition tables, so I needed it. If I use raidstart, I get interesting results:

raidstart /dev/md0 works without any trouble.
raidstart /dev/md1 gives lots of debugging info, and doesn't work. I can't understand why it says 'hdi appears to be on the same physical disk as hdi2' - and why it is referring to hdi at all.

yes | mkreiserfs /dev/md0
yes | mkreiserfs /dev/md

and shouldnt that be md1 ?

Yes, that's a typo in the mail (not in the script, I could mount it just fine).

Thanks,

It turned out the kernel I did this with was compiled like this:

#
# Multi-device support (RAID and LVM)
#
CONFIG_MD=y
CONFIG_BLK_DEV_MD=m
# CONFIG_MD_LINEAR is not set
CONFIG_MD_RAID0=m
# CONFIG_MD_RAID1 is not set
CONFIG_MD_RAID5=m
# CONFIG_MD_MULTIPATH is not set
# CONFIG_BLK_DEV_LVM is not set
# CONFIG_BLK_DEV_DM is not set

and those modules weren't loaded. After recompiling the kernel with all raid-options on and in the kernel, it works.

It's strange, however, that you can create a raid partition without raid support until you reboot.

You'd expect to have 'mkraid' say:

'no RAID support in kernel - aborting'

or something like that.

Kind regards,
Jurriaan
