TEll something which a normal person can understand.......not something for a filesystem maker

Actually, I am a normal person, the last time I checked.

I suggested that article because I thought it would explain it better than I could. I barely understand this myself, but I thought I would give it a shot since nobody more knowledgeable was chiming in (and still hasn't).

According to Wikipedia, Metadata (http://en.wikipedia.org/wiki/Metadata) is data about other data. So according to our blogger:


only writes the metadata to the journal—not the actual data

which means - as I understand it - you could potentially experience data loss in the event of a crash.

EXT3

1) It's stable.

2) It's the default for Ubuntu.

3) No reason to change.
