Formatting a Partition in Ubuntu Server
sudo mkfs…
SWAP
sudo mkswap /dev/sda5
EXT4
sudo mkfs.ext4 /dev/sda5
Automount Partitions at startup in Ubuntu Server
1. sudo gedit /etc/fstab
2. now the fstab file is open in nano. you need to add an entry for the partition to automount it at startup.
the format of a new entry is like this:
file_system mount_point type options dump pass
you will see this in the file and you need to add your new entry under this line.
brief explanation of the above format:
- file_system = your device id.
use this:
/dev/sdax ( you should check it with sudo fdisk -l)
it may be /dev/sdbx or /dev/sdcx if you have more than one disks connected.
- mount_point =where you want to mount your partition.
use this:
/media/user/label
here user is your user name, label is “software”, “movies” or whatever label your partiton have.
- type=fat32,ntfs, ntfs-3g,ext2,ext4 or whatever your partition type is.
- options =mount options for the partition(explained later).
- dump=Enable or disable backing up of the device/partition .usually set to 0, which disables it.
- pass =Controls the order in which fsck checks the device/partition for errors at boot time. The root device should be 1. Other partitions should be 2, or 0 to disable checking.
so for auto mounting case the above format reduces to:
/dev/sdax /media/user/label type options 0 0
(you can check the type with sudo fdisk -l)
the options field:
sync/async – All I/O to the file system should be done synchronously/asynchronously.
auto/noauto – The filesystem will be mounted automatically at startup/The filesystem will NOT be automatically mounted at startup.
dev/nodev – Interpret/Do not interpret character or block special devices on the file system.
exec/noexec – Permit/Prevent the execution of binaries from the filesystem.
suid/nosuid – Permit/Block the operation of suid, and sgid bits.
ro/rw – Mount read-only/Mount read-write.
user/nouser – Permit any user to mount the filesystem. (This automatically implies noexec, nosuid,nodev unless overridden) / Only permit root to mount the filesystem. This is also a default setting.
defaults – Use default settings. Equivalent to rw, suid, dev, exec, auto, nouser, async.
_netdev – this is a network device, mount it after bringing up the network. Only valid with fstype nfs.
now the final format reduces to (for auto mount):
/dev/sdax /media/user/label type defaults 0 0
for ntfs
/dev/sdax /media/user/label ntfs defaults 0 0
for ext4
/dev/sdax /media/user/label ext4 defaults 0 0
etc…..
you can change defaults by your own configuration, like
/dev/sdax /media/user/label ext4 rw,suid,dev,noexec,auto,user,async 0 0
etc…
you need to add entry for each partiton you want to auto mount.
3. save and exit the file then restart
