I just got my RAID5 with three disks setup yesterday (hdb, hdc, hdd). I
created it with this command:
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/hdb /dev/hdc dev/hdd
mdadm --detail --scan >> /etc/mdadm.conf
mkfs.ext3 -j -O dir_index /dev/md0
mount /dev/md0 /storage
I copied tons of stuff to the RAID array. Over night a disk failed
already and I got this:

How come the array is still not up and running on hdc and hdd? As a
matter of fact I don't see hdd anywhere in the log snip above. Am I
hosed already or is there any recovery for this? Unfortunately, I don't
have a backup for some of the data.
Thanks,
James
