4.6. Removing a partition with parted

Procedure

1. Start the interactive parted shell:

   # parted block-device

   • Replace block-device with the path to the device where you want to remove a partition: for example, /dev/sda.

2. View the current partition table to determine the minor number of the partition to remove:

   (parted) print

3. Remove the partition:

   (parted) rm partition-number

   • Replace partition-number with the partition number you want to remove.

   The changes start applying as soon as you enter this command.

4. Verify that you have removed the partition from the partition table:

   (parted) print

5. Exit the parted shell:

   (parted) quit

6. Verify that the kernel registers that the partition is removed:

   # cat /proc/partitions

7. Remove the partition from the /etc/fstab file, if it is present. Find the line that declares the removed partition, and remove it from the file.

8. Regenerate mount units so that your system registers the new /etc/fstab configuration:

   # systemctl daemon-reload

   重要

   To remove a partition mentioned in /proc/cmdline or that is part of an LVM, see Configuring and managing logical volumes, and the dracut(8) and grubby (8) man pages on your system.
