Cannot pack Data.fs, Permission Denied error
I (still) cannot pack my ZODB via the Web. This has been vexing me for months. I get this error: Error Type: IOError Error Value: [Errno 13] Permission denied: '$ZOPEDIR/var/Data.fs' I am running Zope on port 80, so I changed the ownership of the $ZOPEDIR/var directory to root. Zope is started as root, but with the "-u zopeUser" option (yet the first zope process is still owned by root (see below) is that right?). Are there some other permissions I need to change to be able to pack the database via the Zope Management Interface? (Changing all the contents of var to root ownership did not fix.)

Hi John, Change the permissions of the var dir and all of its its contents to be writable by the -u user. Then start Zope as root with the -u switch. That should solve the problem. This problem is a symptom of the way Zope 2.6 and prior handle UNIX setuid wrt log files and database files. Zope 2.7 handles it differently and does not have this problem. - C On Wed, 2003-09-03 at 18:09, Jon Whitener wrote:

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.)
