Hi After failing to resolve this problem at the time of install (d-i rc2), I created a Raid1 array manually.
This box has 1 80Gb ATA disk with sarge installed. Plus 2 SATA 120Gb drives with the following: description: RAID bus controller product: 82801EB (ICH5R) SATA (cc=RAID) vendor: Intel Corp. physical id: 1f.2 bus info: [EMAIL PROTECTED]:1f.2 version: 02 clock: 66MHz I created the raid device with: mdadm -Cv /dev/md0 -n2 -l1 /dev/sda1 /dev/sdb1 [EMAIL PROTECTED]:~$ sudo mkfs.ext3 /dev/md0 mke2fs 1.35 (28-Feb-2004) Filesystem label= OS type: Linux Block size=4096 (log=2) Fragment size=4096 (log=2) 15007744 inodes, 30013408 blocks 1500670 blocks (5.00%) reserved for the super user First data block=0 916 block groups 32768 blocks per group, 32768 fragments per group 16384 inodes per group Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872 Writing inode tables: done Creating journal (8192 blocks): done Writing superblocks and filesystem accounting information: done This filesystem will be automatically checked every 31 mounts or 180 days, whichever comes first.

I'm stumped ;) Regards Clive -- www.clivemenzies.co.uk ... ...strategies for business -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
