WHM / Rearrange an Account

I recently bought another block of storage from my provider and following their guide, I rearranged my accounts to it: 1. sudo mkfs.ext4 /dev/vdb 2. sudo mkdir /mnt/vol-us-1 3. sudo mount -t ext4 /dev/vdb /mnt/vol-us-1 4. bin/bash -c "if [ $(cat /etc/fstab | grep -i /dev/vdb | awk '{print $1}')!="/dev/vdb" ]; then sudo bash -c 'echo \/dev/vdb /mnt/vol-us-1 ext4 defaults,nofail,discard,noatime 1 2\ >> /etc/fstab';fi" This worked initially, but then I ran through an upgrade for WHM and I lost my settings, and the storage block seemed to have been wiped. I was able to recover from a backup, but not entirely. ***I can see in my Disk Usage report that the mount exists:*** ***But then trying to move my account, WHM doesn't let me do it:***
