Removing Storage

The process of removing storage from a Red Hat Enterprise Linux system is relatively straightforward. Here are the steps that are specific to Red Hat Enterprise Linux:
  • Remove the disk drive's partitions from /etc/fstab
  • Unmount the disk drive's active partitions
  • Erase the contents of the disk drive
The following sections cover these topics in more detail. Remove the Disk Drive's Partitions From /etc/fstab
Using the text editor of your choice, remove the line(s) corresponding to the disk drive's partition(s) from the /etc/fstab file. You can identify the proper lines by one of the following methods:
  • Matching the partition's mount point against the directories in the second column of /etc/fstab
  • Matching the device's file name against the file names in the first column of /etc/fstab


Be sure to look for any lines in /etc/fstab that identify swap partitions on the disk drive to be removed; they can be easily overlooked.
