FreeBSD server for sons tv shows. please help

[Brent Clark]

Good day

Im not it its because of a power failure or what, but for some reason my 
'download server', has lost its raid (0/ stripe).

Im trying to fix this, for the raid contains quite a few shows for my son.

If I go

[root at torry /usr/home/bclark]# gstripe list
Geom name: st0
State: UP

I see 'State: UP'

if i:
[root at torry /usr/home/bclark]# mount -t ufs /dev/stripe/st0a /mnt/
mount: /dev/stripe/st0a: Invalid argument

[root at torry /usr/home/bclark]# fsck /dev/stripe/st0a
fsck: Could not determine filesystem type

[root at torry /usr/home/bclark]# fsck_ufs /dev/stripe/st0a
** /dev/stripe/st0a

ioctl (GCINFO): Inappropriate ioctl for device
fsck_ufs: /dev/stripe/st0a: can't read disk label

If someone could help, it would be appreciated, of what the next step 
is, it would be appreciated.
