What ext4 really needs is ...What ext4 really needs is ...Posted Mar 20, 2007 9:44 UTC (Tue) by sdalley (subscriber, #18550)Parent article: The 2007 Linux Storage and File Systems Workshop
If I had to vote for one feature in ext4 that isn't there already, it would be file-level checksumming/correction, similar to that described in http://www.cs.wisc.edu/adsl/Publications/iron-sosp05.pdf . It's disconcerting not to be able to be sure that the data you got back from a file might not be the data you put in because of a PSU glitch or a high-flying write. Nice to have super performance, compact packing, squillion-byte limits etc etc, but reliability trumps these every time.

Having some redundancy in the filesystem (reiser4 promised to bring that, zfs as well) would be great as well, to allow users to recover bad files.
