I have a serious problem with 2.1 and md too.

/etc/mdtab looks like this:
# mdtab entry for /dev/md0
/dev/md0 raid0,8k,0,53200828 /dev/sde1 /dev/sdf1 /dev/sdg1

and mdadd/mdrun works fine:

#mdadd -a
REGISTER_DEV sde1 to md0 done
REGISTER_DEV sdf1 to md0 done
REGISTER_DEV sdg1 to md0 done

#mdrun -a
raid0 personality registered
raid0 : Allocating 8 bytes for hash.

but mke2fs fails miserably:

#mke2fs /dev/md0

...screen after screen after screen of this...

changeing the md to use /dev/sde /dev/sdf /dev/sdg has no effect. using
the drives standalone works 100%

....any ideas?

clean 2.1.89, md 0.35

Drives are 3 of theese:

kernel: Vendor: QUANTUM Model: FIREBALL ST2.1S Rev: 0F0C
kernel: Type: Direct-Access ANSI SCSI revision: 02
kernel: Detected scsi disk sde at scsi0, channel 0, id 4, lun 0

Best regards, Tomas
