[Zope] Cannot pack Data.fs, Permission Denied error

[Jon Whitener]

Solved!

I created a 'zope' group (this is on Linux), and added to the group both root and zopeUser (my -u user).  (Whether root really needed to be added to the group, I don't know.)

Next, I set the group name to zope for the $ZOPEDIR/var directory and everything in it:
chown :zope var
chown :zope var/*

Then changed permissions to allow members of the zope group to write var and its contents:
chmod g+w var
chmod g+w var/*

I stopped and restarted Zope and VIOLA: I was able to pack my morbidly obese 40MB ZODB to a spindly 5.8MB!  I am happy!

(Interestingly, after packing the ZODB, the group of the Data.fs file and Data.fs.index reverted to 'zopeUser'.  Nonetheless, I was able to pack again without error.)

Thanks,
Jon
