Identically partition disks.. the easy way!
Was just looking into a software RAID howto.. for no reason really, but kinda glad I did! When you set up software raid you want to make sure all disks are partitioned the same, right. so check this out:
3. Create partitions on /dev/sda identical to the partitions on /dev/sdb:
sfdisk -d /dev/sdb | sfdisk /dev/sda
That’s a much easier way 😉
