NOTE: I added an additional 128G disk via VMware which is seen as: /dev/sdb
I created (1) 25G partition to be allocated for the /var/log/ciena partition
Create 1 partition for Ciena logs and one partition for Docker
# fdisk /dev/sdb
Welcome to fdisk (util-linux 2.23.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
