Are these issues really unique to Ext3?Are these issues really unique to Ext3?Posted Sep 2, 2009 7:01 UTC (Wed) by Cato (subscriber, #7643)In reply to: Are these issues really unique to Ext3? by pr1268 Parent article: Ext3 and RAID: silent data killers?
See http://www.cs.wisc.edu/adsl/Publications/iron-sosp05.pdf for a good paper on how hard disks fail, including partial failures, and the failure/recovery behaviour of ext3, reiserfs, JFS and NTFS. Also talks about ixt3, an ext3 variant by the authors that's intended to have a stronger and more consistent failure/recovery model. This includes journal and data block checksums.
There was a 'journal checksum patch' for ext3 by the authors, I think, but I can't track it down.
Not sure about NTFS, but HFS+ does seem to have journal checksums - see http://developer.apple.com/mac/library/technotes/tn/tn115...
