I presume so since google turns-up a lot of discussions of problems from a few years ago. You'd probably have to do it from a different boot disk and either add a journal partition to an existing root or create partitions for a new install. IIWY I'd try it out first on a disposable drive before doing anything dangerous. I don't think it's worth doing unless you have a large root with /usr on it. If you keep /tmp files off a small root, it doesn't get many writes.=20 >=20 > Nowadays SU+J should be used instead of gjournal No, it shouldn't, they do different things. SU+J is a replacement for fsck -B which recovers lost blocks and inodes in the background. It's not a journalled filesystem in the normal sense of the term. I don't know if it's been improved but SU+J got a reputation for being unreliable.
