Default Can't mount RAID5...

Hi all,

just migrating from Mandriva to Debian and I can't mount my raid array no more.
When I boot on Mandriva the raid is ok. I can mount it. Debian just doesn't want!
I've run Fsck from mandriva, no problem found.

Surely i've missed something but I can't figure what...

Any clue???

Dmesg gives:

And near the end :

EXT3-fs error (device md0): ext3_check_descriptors: Block bitmap for group 880 not in group (block 67108864)!
EXT3-fs: group descriptors corrupted!


If I try to mount :

#mount /dev/md0 /mnt/raid
mount: wrong fs type, bad option, bad superblock on /dev/md0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Is it software or hardware RAID? What kind of hard disks do you use (SATA, IDE,...)? Which Debian kernel?

Kernel is 2.6.17-2-amd6, RAID is software with 4 IDE disk and a PCI IDE controller:

02:0a.0 Mass storage controller: Promise Technology, Inc. 20269 (rev 02) (prog-if 85)
Subsystem: Promise Technology, Inc. Ultra133TX2

Mandriva's kernel is 2.6.17 based.

What file system do you use on the disks? Is it supported by your Debian kernel?

File system is ext3, and there's no problem with the two other non raid ext3fs hard disks.
