I want to shrink my encrypted ext4 partition with KDE partition manager, but the minimum-, maximum- and the current size are the same value. How do I change that?
Shrinking is a risky business, make sure you backup everthing!
- shrink the unencrypted filesystem
- shrink the luks device
- shrink the partition
Depending on the filesystem used, sometimes this already stops at step 1 since not every filesystem supports shrinken (
f2fscomes to mind)
Another way to go would be to:
- fully backup the partition contents
- delete and recreate the partitions with the new size
- restore the contents
