df wont show true RAID size

[sprunknwn]

I'm trying to RAID 0 2 500gb sata hdd's.

i did -

fdisk /dev/sdb , new partition, primary, 1, type fd, w
fdisk /dev/sdc , new partition, primary, 1, type fd, w

then i created the raid -
mdadm /dev/md10 -C -l 0 -n 2 -c 256 /dev/sdb1 /dev/sdc1

filesystem -
mkfs.ext3 -m0 -T largefile4 -Osparse_super /dev/md10
tune2fs -i0 -c0 /dev/ md10

added a mount in fstab -

/dev/md10 /Clips auto defaults 0 0

and a mounting point -

mkdir /Clips

mount and i see this instead of 1000gb -
/dev/md10 72034 32152 39882 45% /Clips

70gb?!??!?

what did i do wrong?

That looks like about 70Mb, not Gb. I'm not sure what /dev/md10 actually is at this point. I think your create command should have been:

mdadm -C /dev/md10 -l 0 -n 2 -c 256 /dev/sdb1 /dev/sdc1

I.E. the raid device spec goes after the -C. You didn't get an error?

What do you get from:

mdadm --detail /dev/md0
?

What outputs:

$ cat /proc/partitions

also, you might want to use a more readable form for df:

$ df -h

BTW: Notice that if *any* of both drives fail, you loose *all* data on both drives. You effectively double the failure rate with RAID-0 by having a single filesystem across two drives. I'd always choose for at least RAID-5 or at least make sure you have a back up somewhere else, 1TB is an awful lot of data to loose.

Hi!

Are you sure you are not looking to sda?
try "df -h"
your clip player is sdb and sdc (md10).
