Hello Ivan! Thanks for the hint! :-) :-)
When I have created a new filesystem type 2 (UFS2) with -J switch,
then on mount I get this error that filesystem has journaling enabled
but no provider is specified, so it looks like no journal is enabled?
Does newfs -J create journal as well?
According to man newfs:
-J Enable journaling on the new file system via gjournal. See
gjournal(8) for details.
This is why I have started reading man gjournal and saw an example
where journal is first created before newfs...
Will "gjournal label -f" erase all data on partition with existing newfs/ufs2?
Thanks!! :-)
