Folks,
I messed up slightly when creating a new 6-disk raid6 array, and am wondering
if there is a simple answer. The problem is that I didn't partition the drives,
but simply used the whole drive. All drives are of the same type and using the
Supermicro SAT2-MV8 controller.
This is a problem because mdadm doesn't find the component drives... I can only
start the array by using "mdadm --assemble /dev/md3 /dev/sd{drives}". While
this works it means my system doesn't boot very easily :-(
For fixes I can think of the possible solutions:
- Modify the startup script to do the mdadm --assemble /dev/md3
/dev/sd{a,b,c,d,e}. Is there any other disadvantage of this?
- Use fdisk to create whole-disk partitions - but would this damage the
already stored data?
- Start again doing it right.... But this will take >12 hours and has a chance
of failure!
Any thoughts?
Regards,
Ruth
