2. Confirm that partition with your file system is _not_ 4 sectors aligned. If it is not 4 sectors aligned, it is safe for gjournal to use its last sector for metadata. You can verify this by running:

test `diskinfo /dev/<data_partition> | awk '{print $4}' | xargs -J X echo X % 4
| bc` -eq 0 && echo ok || echo not ok

Then you need to run those commands:

# gjournal label /dev/<data_partition> /dev/<journal_partition> # tunefs -n disable -J enable /dev/<data_partition>.journal

Sounds like a "gjournal testalignment /dev/partition" would be a very useful
thing. Or even just doing it as part of gjournal label?

Sounds fair. I integrated those checks into 'label' subcommand:

When configuring journaling on one provider only, check if UFS file system exists there and if it exists demand -f flag before destroying it. When configuring journaling on two providers, check if UFS exists on the data provider and if the last sector is used by the file system. If it is used, demand -f flag before overwritting it.

Next, I want to think a bit how to make those checks more general, so they can be used also in other classes.
