I've got a file server running Ubuntu Server LTS 16.04.1.
Originally it had 2 hard drives, the first running my OS (swap and boot), the second was strictly a media storage drive (1 whole partition with ext4).
I've added a third drive and used parted to create the gpt disk parition table and set it to use the entire disk for an ext4 partition. That went okay.
I can see the disk and partition in /proc/partitions as well as the device for the disk and partition in /dev/sdc and /dev/sdc1.
The problem is the mounting. When I edit the /etc/fstab to include the third drive and reboot, the machine boots up to a maintenance prompt. When I change the /etc/fstab back to comment out the third drive, the machine boots normally. I feel like I'm missing something because my /etc/fstab should be working fine.
This is what I put in the /etc/fstab:
# <file system> <mount point> <type> <options> <dump> <pass># / was on /dev/sda2 during installationUUID=b4022d1c-ecc2-4902-ace7-f1a0c0e3ae1b / ext4 errors=remount-ro 0 1# /boot/efi was on /dev/sda1 during installationUUID=055C-5059 /boot/efi vfat umask=0077 0 1# swap was on /dev/sda3 during installationUUID=6eedbf37-0c8c-45dc-abca-4361aba72045 none swap sw 0 0#Secured Shared Memorytmpfs /run/shm tmpfs defaults,noexec,nosuid 0 0#Secondard Drive/dev/sdb /mnt/Media ext4 defaults 0 2#Third Drive/dev/sdc1 /mnt/MediaArchive ext4 defaults 0 2
