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 @dgriffith@aussie.zone.
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 @dgriffith@aussie.zone comment
Simply change the partition size back to exactly what it was before. Larger might be acceptable too, not sure
That's correct answer. If you did not write anything in the space you freed (i.e. did not create a partition there AND format it), your data is not damaged.
also format does not actually completely overwrite most of the data, so you'll probably just end up with a couple corrupted blocks, which are fixable with some minor data loss
It should.
It is.
Yeah, it worked.
Solid work, now set up backups haha
