Amen, Brother!
Yes, users can do what you said with rsync, but it is important that it
be no more work than specifying a --use-versioning mount option, and
even that is beyond most users (but that is where defaults come in to
help them).
The namespace for the past versions should be as cleanly done as WAFL
does them. Whether space gets freed automatically when space gets <10%
is another mount option. Where we might do better than WAFL is in
allowing touching filename/..../checkin to cause a version to get
recorded, rather than doing it at particular times.

Of particular concern is that the name space should (somehow) allow me to
easily grab version by date, even if the file hadn't changed for the two
weeks before that, and in fact still hasn't changed... Make it really easy to
grab all or some files by wildcard and with a specific revision, even when
not every file changed with that revision.
Oh, BTW. "The slowdown" as I called it is still there. I guess I spoke to
soon. The specific symptom is that the effected process locks for a time,
usually just a second or two, but sometimes a minute or two and and at least
once for many many minutes. I think that the crash (soft lockup) that I
reported earlier is related as well. And it sounds like the comment that
rvalles had about lockups with mmaped files, except that it doesn't lock up
permanently. Just for a second or three usually.

yes, its exactly the same with my case. it locks up just for few
seconds, sometimes one/two minutes when using for example vim... but
sometimes it locks up completly, machine is responding to ping but i
cannot login, dns is not working and all services seems down. (but it is
replying to ping)
it can happen up to 2-3 times per day. (usually only once per day or
once per 2 days)
there is completly no info about anything in any log files.
i already installed latest kernel 2.6.14.2 and lates 2.6.14-1 reiser4
patch and its the same.
My users are getting angry becouse of the downtimes... is this bug
noticed by dev team ? This seems really serious, as it is causing
sporadic crashesh and often short lock-ups. Any quick-fix please? It is
happening for quite some time now so this is not new bug. thats why i
keep asking... is it worked on or not?
thanks in advance
