"rsync" on XFS mounted wsync + execute "sync" afterwards?
I don't really agree with it, but pitrery uses 'dd' with 'conv=fsync'. As far as I know, there isn't a way to force 'rsync' to run an fsync() at the end, and executing a 'sync' afterwards, while it should work, seems likely to cause you a lot more troubles.. In the end, I wouldn't suggest trying to hack up your own scripts to do any of this- use one of the existing tools. It's a lot more complicated than I think you're appreciating. Thanks, Stephen
