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

Yes a back up is possible. Don’t back up partitions, back up the whole device. All 150+g at once.

Whenever you try to mount the device or the filesystems, make sure to mount it read-only so that no changes are written to the device.

Also, shrinking 84g of data into 32g is definitely not possible. Just changing the fdisk partition table doesn’t shrink or relocate the data. You need a filesystem-aware resizing tool to shrink the filesystem before shrinking the partition.

Hopefully you can just change the partition table back to the original values and get a clean fsck.
