From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

How do I properly resize my LVM partitions when it is inside LUKS?

Do I have to boot in a USB to do it or can it be done while the crypt is open/being used? I need to resize my root partition.

#linux #lvm #luks @linux

@[email protected] All's good. Yea, reason for the post was that even though I took the partitions offline it wouldn't still let me resize. So I think the best next move would be just booting into a USB and see if it lets me.

The whole disk well, only the boot is separated. The rest of the partition has the whole space controlled by LVM. Interestingly even though that may be the setup something was just rejecting my resize request.

Sadly have more to say but Mastodon limit is hitting haha. nutshell

Did you already shrink the filesystem? I think lvresize will refuse to shrink if the FS is too big (not sure - I don't shrink volumes often).
