I want to use the Btrfs partition type for my main ("/") logical volume which is under encryption. The encrypted LVM will occupy my entire device aside from the two small "EFI-system" and "Boot" partitions.
I want to use Btrfs because of the Copy-on-Write feature. However I'm not sure whether it's OK to use Btrfs specifically for an encrypted logical volume. Could this cause any issues like data loss or severely hurt my SSD's life expectancy due to the encryption of a Btrfs volume? I'm just not entirely sure how well Btrfs works with encryption.
The Debian installation offers an easy and guided partitioning procedure with LVM and encryption all set while using ext4 for the logical volumes in it. Is this default choice of ext4 necessary for the encryption to work properly, or should I simply change it from ext4 to Btrfs and move on?
