Hello,
I've found a couple of threads on the list where people were trying to
request objects from the cache after a restart, but none of them seem
to have been successful, and the threads ended without any solution.
My question is: what am I missing to be able to:
- fetch an object from a backend to prime the cache
- fetch this object a 2nd time to check I get a HIT
- restart varnish (as in /etc/init.d/varnish restart)
- fetch the object and get a HIT.
Has someone actually managed to have data persist in the cache across
restarts ?
Hum, must I interpret the lack of answers as "no, no one never got
persistence working" ? And therefore, should I open a bug report ?
Thanks for any hints :-)

Marc,
My understanding is that -spersistent enables the cache to remain full
whilst a child varnish process restarts, but not for the parent process
(that you're restarting via /etc/init.d) to restart. But, there's
definitely a lack of documentation at
http://varnish-cache.org/docs/reference/varnishd/#storage-types, which
just describes the persistent storage option as "New, shiny, better.".
Can someone who knows more about this feature add some comment here?
Rob
