Having read about the pros and cons of "LUKS on LVM" vs "LVM on LUKS" I came to the conclusion that "LUKS on LVM" does not provide live resize. But why? And is this even true as of todays implementations?
For the context this is what I have in my /etc/crypttab:
decrypted_root /dev/vg_ubuntu/LV_crypted_root none luks
This is my /etc/fstab:
/dev/mapper/decrypted_root / ext4 errors=remount-ro 0 1
Here is what I did:
lvextend -L +10G /dev/vg_ubuntu/LV_crypted_root cryptsetup resize decrypted_root resize2fs /dev/mapper/decrypted_root
And now my overall question: What could possibly go wrong with this?
