Thank you for the reply. I've tried experimental but without success.

To be clear:

I have RAID1 volume build from /dev/sda5 and /dev/sdb5

cat /proc/mdstat 
Personalities : [raid1] 
md1 : active raid1 sda5[0] sdb5[1]
      244195192 blocks super 1.2 [2/2] [UU]
      
md0 : active raid1 sda1[0] sdb1[1]
      975860 blocks super 1.2 [2/2] [UU]

This volume is partitioned:

fdisk -l /dev/md1

Disk /dev/md1: 250.1 GB, 250055876608 bytes
2 heads, 4 sectors/track, 61048798 cylinders
Units = cylinders of 8 * 512 = 4096 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00071212

    Device Boot      Start         End      Blocks   Id  System
/dev/md1p1             257     2621696    10485760   83  Linux
/dev/md1p2         2621697     3670272     4194304   82  Linux swap /
Solaris

Debian squeeze is installed on /dev/md1p1 with ext4

Whan I'm trying to install grub, I get:

# grub-install -v
grub-install (GRUB) 1.99+experimental

# grub-install /dev/md1p1 
/usr/local/sbin/grub-probe: error: unknown filesystem.
Auto-detection of a filesystem of /dev/md1p1 failed.
Please report this together with the output of
