Comment 4 guazhang@redhat.com 2022-12-20 04:26:36 UTC

Hi,

[root@storageqe-104 ~]# echo 'redhatredhat' |cryptsetup reencrypt  --encrypt /dev/loop0  --header  /dev/loop0  --type luks2  -q
Encryption without detached header (--header) is not possible without data device size reduction (--reduce-device-size).
[root@storageqe-104 ~]# $?
-bash: 1: command not found
[root@storageqe-104 ~]# 

test pass with fixed package,
