In Reply to: [gentoo-user] dm-crypt + ext4 = where will the journal go? by "Roland Häder"
1 The journal is generally located on the partition in question. If the
2 partition is encrypted the journal should also be encrypted. You can use
3 `tune2fs -l` to list the contents of the partition's superblock which will
4 have details on the partition such as journal location, etc...
