=====Linux Disk Partition and Format Notes =====

====Some basic tools====
  *''ls -l /dev/disk/by-uuid/'' will list the disks with UUIDs
  *''lsblk''  to list partitions (or list block devices)
  *''lsblk -f'' or ''blkid''  to list the UUIDs
  *''sudo blkid'' will list data blocks

----
====parted====
==There would seem to be a number of partition tools for Linux CLI.==
  *''sudo parted -l''  - to see all available partition information
  *''sudo parted /dev/sda'' - to partition the specific drive
When in parted:
  *''print'' to see current partition information
  *''mkpart help'' to list option
  *''mklabel gpt'' to give drive label gpt
  *''mkpart help mkpart'' to list specific help items on mkpart
  *''mkpart primary ext4 0% 100%'' to make a partition that take the full optimised drive area
  *''rm 1'' to remove partition 1

----
====Format====
''sudo mkfs.ext4 /dev/sda1'' - to format the drive

----
====Fstab====
''sudo vim /etc/fstab'' -to edit the boot  disk mount table, remember to make matching mount point directories

----

====mount====

===Local Device===
**mount -t ext4 /dev/sdb1 /run/media/diska**

===NFS Device===

To mount a NFS manually: 
  *''sudo mount -t nfs -o rw,vers=4 192.168.1.5:/export/Disk1 /mnt/backup1''
  *''sudo mount -t nfs -o rw,vers=4 192.168.1.5:/export/Disk2 /mnt/backup2''

Where:
  * ''-t nfs'' : type nfs
  * ''-o'' : options, options are separated by commas with no spaces
    * ''rw'' : read / write
    * ''vers=4'' : version 4 of nfs
  * ''192.168.1.5:/export/Disk1'' is the remote exported NFS mount point
  * ''/mnt/backup1'' : is the local mount point, note this directory must exist, ideally empty, any existing contents are usually invisible and otherwise ignored

----
====unmount====
''sudo umount /run/media/diska''


----

====mount at boot====
''sudo vim /etc/fstab''
