[Zope-dev] 2.7.0 corrupt Data.fs

I'm seeing changes to the ZODB getting lost on reboot. I think it's because there are no fsync() calls being issued by Zope or even by zopectl on stopping Zope but I can't be sure. I'm using /instance/bin/zopectl {start|stop} for controlling Zope. I added a "sync" command to my /etc/init.d/umountfs script (Debian Woody) and this seems to have fixed the problem. I know postgresql syncs to disk for every transaction by default, does Zope? Tom
