Removing a Partition

Warning

Do not attempt to remove a partition on a device that is in use.

Before removing a partition, boot into rescue mode (or unmount any partitions
on the device and turn off any swap space on the device). Start parted, where
/dev/sda is the device on which to remove the partition:
  • parted /dev/sda
View the current partition table to determine the minor number of the partition to
remove:
  • print
Remove the partition with the command rm. For example, to remove the
partition with minor number 3:
  • rm 3
The changes start taking place as soon as you press Enter, so review the
command before committing to it. After removing the partition, use the print
command to confirm that it is removed from the partition table. You should also
view the output of
  • cat /proc/partitions
to make sure the kernel knows the partition is removed. The last step is to
remove it from the /etc/fstab file. Find the line that declares the removed
partition, and remove it from the file.
