Test with raid 6 software

[Pol Hallen <deben@fuckaround.org>]

Good day :-)

I've 8 sata disk on raid 6 software (debian stable).

For purpose test I stopped 3 disks of the array.

Now I rebooted and I tring to re-assemble the array but without successful..

mdadm -A /dev/md0
mdadm: /dev/md0 assembled from 5 drives and 3 spares - not enough to 
start the array.

cat /proc/mdstat

Personalities :
md0 : inactive sdb[0](S) sdi[10](S) sdk[9](S) sdj[8](S) sdf[4](S) 
sde[3](S) sdd[2](S) sdc[1](S)
      3907091968 blocks

unused devices: <none>

Consider the data there are on the raid, and there aren't any disks 
failure, is there a way to re-assemble the same raid and maintan the data?

Thanks
Pol
