Useful article extending VMware disk extend the logical volume and resize the underlying file system with the lvextend command

This linked article by Shehu Awwal, Red Hat's "Enable Systadmin" area is very good if you have to extend an LVM with Linux.

Verified (by me) 2022.07.20

Environment

-VMware instances
- RHEL 7, 8, have not tested on 9 yet

Issue

• Within VMware, you can extend an existing disk and then take the following steps in the article below to extend the disk within the Operating System (OS)
• This article at https://www.redhat.com/sysadmin/resize-lvm-simple is highly useful, one minor edit...
• The
  Copy Copied!

  lvextend

  command can extend the filesystem if you include "
  Copy Copied!

  -r

  ", omitting the
  Copy Copied!

  xfs_growfs

  command mentioned (for example) in paragraph 6.1 of this Red Hat documentation, look for the NOTE See
  Copy Copied!

  Resolution

  below:

Resolution

How do I do an lvextend command extend the file system all at once, skipping the "

Copy Copied!

xfs_growfs

" command?

    You can use the -r option of the lvextend command to extend the logical volume and resize the underlying file system with a single command:

lvextend -r -L 3G /dev/myvg/mylv

Another example, to take the remainder of the added storage:

lvextend -r -l 100%FREE /dev/myvg/mylv

This allows you to SKIP using the command

xfs_growfs

• This is a discussion, not a Red Hat solution.
