Linux Disk Partition and Format Notes
Some basic tools
lsblk to list partitions (or list block devices)
lsblk -f or blkid to list the UUIDs
parted
There would seem to be a number of partition tools for Linux CLI.
sudo parted -l- to see all available partition informationsudo parted /dev/sda- to partition the specific drive
When in parted:
printto see current partition informationmkpart helpto list optionmklabel gptto give drive label gptmkpart help mkpartto list specific help items on mkpartmkpart primary ext4 0% 100%to make a partition that take the full optimised drive arearm 1to 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 ext2 /dev/sdb1 /mnt
NFS Device
To mount a NFS manually:
sudo mount -t nfs -o rw,vers=4 192.168.1.5:/export/Disk1 /mnt/backup1sudo 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 spacesrw: read / writevers=4: version 4 of nfs
192.168.1.5:/export/Disk1is 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
umount /mnt
mount at boot
sudo vim /etc/fstab
