In Fedora 41 it was possible in the advanced installer to select 4K LUKS sectors when creating an encrypted partition on a SSD drive that only supports 512 sectors. With the new installer I cannot find this option that significantly benefits my setup.
Is this option really removed? If so, should I manually in the shell create the partitions?
Easy but somewhat time consuming; once the system is installed you can run:
Check sector size:
sudo cryptsetup status <device>
Reencrypt:
sudo cryptsetup reencrypt --sector-size 4096 <device>
Thanks for the tip.
This is time consuming since it will write the whole partition as it does not know that it is mostly unused. Still it is a valid option if one decides against using command line during the install or wants to improve performance of an existing installation.
I wish that the option would be kept. Some SSDs allow to change the reported logical sector size to 4K (LUKS will use that then), but not Samsung ones. And for them 4K LUKS sectors improve performance by non-trivial amount with no drawbacks in practice.
