I'm trying to reencode a crypto_LUKS partition from -c aes-cbc-plain -s 128 -h sha1 like this: cryptsetup-reencrypt -c twofish-xts-plain64 -s 512 -h sha512 -i 2000 -B 32 /dev/sda4 Output I'm getting: Device LUKS-71a94fa6-9c84-45d7-80e8-ee61be3887e0.new is too small. Creation of LUKS backup headers failed. On it is a Physical lvm2-volume that could be shrunken. Is it just a matter of doing that? How much more space is needed??
