Add 'data=journal' to its fsck options. If you want to use full data
journalling for your root parition, add 'rootflags=data=journal' to your
kernel parameters (usually with append= in lilo.conf). By default, an ext3
kernel will mount a partition with a journal as ext3, but only using ordered
mode by default.
Note that ReiserFS does NOT support full data journalling, or even ordered
writes. You can make ext3 use a similar, meta-data only journal with the
'data=writeback' option, but it's very rare that you'd actually want to do
this. :-)
[ ReiserFS is a good choice if you know that you'll be using many (like,
very many) small files, as its directory indexing is a lot better than
ext3's. However, with some clever work done by Daniel Phillips, there will
be even less reason to use ReiserFS soon. On the other hand, ReiserFS 4 will
be very interesting, if only to see if Has Reiser and his team of Russian
slave coders (along with Chris Mason) can create what has been described as
"the photoshop of file systems". Crazy Crack! ]
