Hello all,
Well I pulled my old Ubuntu Server out of the basement to set it up with a newer version f Ubuntu Server. I haven't had the server running since 12.x.x! I installed 18.04.1 LTS to the boot drive, (120GB). I have 3 WD red drives in raid5 originally. I wanted to change to raid10 mdadm style. So I umounted and stopped /dev/md0. Then I lsblk to see the raid members. I had sdb1, sbc1, sdd1. I then did mdadm --zero-superblock of each drive but sdb1 will not zero. I have already removed persistent references in /etc/fstab and commented out the array in mdadm.conf. Then I updated initramfs.
Everything was going good with the new install but I ran into this hiccup redoing my array. I'm not sure what to do at this point. Could someone please give me some guidance on this one? I have been trying to find the solution for a couple hours now. Thank you in advance.
