Hi,
I have a simple question regarding XFS. A while back ago I read a research
paper about the IRON (Internal Robustness) of file systems that tests and
compares various Linux file systems on how they handle data-integrity in case
of a unclean unmount or power failure or even a disk failure. Though I'm not
a file system guru like you guys I learned that XFS does a fairly good job
but fails bad in specific areas, like, and I quote from the paper: "when an
ordered data block write fails, XFS continues to log the failed transaction
to the journal resulting in data corruption"
The paper can be downloaded here: http://www.cs.wisc.edu/adsl/Publications/
(just click on the IRON file systems link for a PDF)
My question is, is it possible to add to XFS more sanity checking (maybe even
CRC checks?) on things like inodes, bitmaps, indirect pointers, etc to
further improve the integrity of XFS?
Thanks, GN
