There was a nice paper published recently (at OLS or maybe I got the link from one of OLS presentations) about an "iron ext3", ext3 modified to withstand various data corruptions caused possibly by hardware failures. In there is also a nice table with comparisons on how different linux file systems stand up to those corruptions: http://www.cs.wisc.edu/adsl/Publications/iron-sosp05.pdf Very good reading to anyone who's concerned about digital data storage. Also, for discussion about cheap storage there's a mailing list called "linux-ide-arrays": http://marc.theaimsgroup.com/?l=linux-ide-arrays&r=1&w=2 Subscribe at http://lists.math.uh.edu/cgi-bin/mj_wwwusr But remember ... "Cheap, fast, reliable. Pick any two, you can't have all three" ... is even more true for storage than for anything else ;) -- Jure Pečar http://jure.pecar.org
