13.3. Removing a Partition
Do not attempt to remove a partition on a device that is in use.
Procedure 13.3. Remove a partition
- Before removing a partition, boot into rescue mode (or unmount any partitions on the device and turn off any swap space on the device).
/dev/sdais 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:
- Remove the partition with the command
rm. For example, to remove the partition with minor number 3:
# rm 3The changes start taking place as soon as you press Enter, so review the command before committing to it.
- After removing the partition, use the
/proc/partitionsto make sure the kernel knows the partition is removed.
# cat /proc/partitions
- The last step is to remove it from the
/etc/fstabfile. Find the line that declares the removed partition, and remove it from the file.
