for example at the end once I clean up the mnt test folder should I run "mount -t ext4 /dev/sdb1/whateverfolderIcreate /images
this would insure that the fog images folder is mounted in side this whateverfoldericreate folder yes?
Linux file system doesn’t work that way, the mount command mounts a partition to a mount point.
In your case you can either mount a new disk to the /images folder as in Sebastians post, or if your linux server uses LVM, you can just add that new disk to the root LVM group and then just extend your root lvm group. Let the LVM disk manager manage how that disk is used. There are many how-tos on how to work with LVM: https://www.rootusers.com/how-to-increase-the-size-of-a-linux-lvm-by-adding-a-new-disk/
