I reinstalled 1.6.1, and I am trying to get my SATA RAID1 and my NVME RAID1 re-established. I don’t care about the data they already have. When I try to add them back via the web interface I get an error message:
failed to delete RAID info: mdadm: Couldn’t open /dev/sdb for write - not zeroing
Can someone help me get beyond this step. I did check to see if they may mounted elsewhere and they are not (lsblk -o NAME,SIZE,FSTYPE,MOUNTPOINTS). They still show being linux raid members….
