Basics

The ordering of /etc/fstab is

1. disk
2. mount point
3. filesystem type
4. options
5. dump
6. pass

Example:

1UUID=877f14e8-4738-46b0-884f-ba330dad1a7d       /mnt/biggie                     ext4        nofail,rw,relatime      0 2
2
3UUID=B21648C416488AF5 /mnt/share ntfs …

RAID5

You will need 4 disks and the mdadm package. The total size will be equal to the disks x 3, because one will be used for redundancy.

1sudo mdadm --create --verbose /dev/*md127* --level=5 --raid-devices=*4* */dev/sdb /dev/sdc /dev/sdd /dev/sde*

Note the variable parts:

• The name of the device could be /dev/md12 or …
