Can i convert a mdadm from raid 6 to raid 0
Can i convert a mdadm from raid 6 to raid 0
I have a machine with 10&10TB of data in raid 6.
I'm looking to convert to Raid 0
I dont really care if I lose the data (I have several copies) I just would prefer daving the time off wiping machine - raid 0 - then transferring it all back again.

You may consider the zfs variant of raid 0. if you have a small dataset than can be moved to 2 drives, you can throw all your data on 2 existing drives, and then add the other drives.
