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.

I was editing my disk and when i wrote the changes and exited cfdisk, no cli command worked. Thats when i realized that im f-ed up.

This what happened: I have 3 partitions, 512M efi, a 100G root partition and some free (unallocated) space. I had 84G worth data in the root patition. I totally forgot that and shrinked the root partition to 32G to extend the free space. I was using cfdisk tool for this. I wrote the changes and rebooted my machine, by long pressing power button coz no cli commands worked after writing those chrnges, to see this.

So is it possible to recover my machine now?

:_ )

SOLUTION Thanks to @[email protected]. cfdisk just updates the partition table. So no worry about data damage . To fix this, live boot -> resize the partition back its original size -> fsck that partition. For more explanation, refer @[email protected] comment

For sure.

For fsck /dev/nvme0n1p2:

The filesystem driver knows the size of the filesystem is larger than the physical size of the partition it is on. Because of that it refuses to do anything with it until that discrepancy is sorted.

Boot to a USB/ISO, run cfdisk, extend the partition size back to original or larger, then run fsck on the partition again.

😭😭😭🤧 THANKS!!

Whrt happened anyway? Why cfdisk didnt wipe the data? I thought it would everything after 32g, but all my data is un touched. What happened?

It's a marvellous feeling, right?

We thank Dave for his decisive contribution. For future occasions try to backup everything before doing operations of this type. This small script works very well for me:

That allows you to backup even hot systems. Just mount an external disc in /home/cya and run the script with sudo...
