I know about XFS's zeroing of files for such files that were still marked as
dirty when the crash occured. I wonder about two things:
o Why are 15-20 minutes old files also wiped out? Are the write-backs that
much delayed (even if there is not other FS/CPU load)?
o What is the best way to find these files (why aren't their names simply
dumped to the kernel logs)? Something like
find . -xdev -type f \! -empty | xargs <grep for non-zero character here>
What's the best expression for the last part?
