Christian, I am well aware that this problem can be solved properly with
snapshots. My point is, that the exact behavior of xfsdump is
"underdocumented". I surprised a few colleagues when I told them that
xfsdump was not atomic...
the following information should IMHO be included into the man pages
and/or the FAQ:
* What happens to files created/deleted (ie. directory modifications)
during a dump. (-> thanks to Ivan this has been resolved)
* What happens to existing files if they are modified (or their metadata
eg. atime) is updated *exactly* when xfsdump is working on that file?
(-> this is not yet cleared up. Maybe xfsdump could lock the file during
dump?)
I would appreciate it a lot if a developer could clarify this.
Another question: Can a frozen filesystem be dumped?
