A big step in the development of a new filesystem is when the developers feel confident enough to start trusting their data to it. For ext4, it appears we have reached that point as Ted Ts'o has switched his laptop to use it
. "So far Ive found one bug as a result of my using ext4 in production (if delayed allocation is enabled, i_blocks doesnt get updated until the block allocation takes place, so files can appear to have 0k blocksize right after they are created, which is confusing/unfortunate), but nothing super serious yet. I will be doing backups a bit more frequently until Im absolutely sure things are rock solid, though!
