As a matter of fact, you CAN enlarge the root filesystem while Ubuntu is running (I learned this recently myself here) - this sounds incredible but it's true :)
Here's the list of steps for a simple scenario where you have two partitions,/dev/sda1
is an ext4 partition the OS is booted from and/dev/sdb2
is swap. For this exercise we want to remove the swap partition an extend/dev/sda1
to the whole disk.
As always, make sure you have a backup of your data - since we're going to modify the partition table there's a chance to lose all your data if you make a typo, for example.
Runsudo fdisk /dev/sda
- use
p
to list the partitions. Make note of the start cylinder of/dev/sda1
- use
d
to delete first the swap partition (2
) and then the/dev/sda1
partition. This is very scary but is actually harmless as the data is not written to the disk until you write the changes to the disk.
- use
n
to create a new primary partition. Make sure its start cylinder is exactly the same as the old/dev/sda1
used to have. For the end cylinder agree with the default choice, which is to make the partition to span the whole disk.
- use
a
to toggle the bootable flag on the new/dev/sda1
Reboot with
- review your changes, make a deep breath and use
w
to write the new partition table to disk. You'll get a message telling that the kernel couldn't re-read the partition table because the device is busy, but that's ok.sudo reboot
. When the system boots, you'll have a smaller filesystem living inside a larger partition.
The next magic command isresize2fs
. Runsudo resize2fs /dev/sda1
- this form will default to making the filesystem to take all available space on the partition.
That's it, we've just resized a partition on which Ubuntu is installed, without booting from an external drive.
