I created a RAID volume with mdadm on a debian system with this command:
I am trying to delete the volume and remove the RAID data from the drives and .config file.
I've tried several things already:
This stopped the array, removed /dev/md0 but left the 4 drives with data so I can't use them to create another RAID volume.
Other things I've tried:
I just can't seem to get there from here.
>:(
Help is truly appreciated!
Code:
mdadm --create --verbose /dev/md0 --level-raid6 --raid-devices=4 /dev/sdb /dev/sdc /dev/sdd /dev/sdeI've tried several things already:
Code:
mdadm --stop /dev/md0Other things I've tried:
Code:
# mdadm --query /dev/sdb
/dev/sdb: is not an md array
/dev/sdb: device 0 in 4 device unknown raid6 array. Use mdadm --examine for more detail.
# mdadm --examine /dev/sdb
