I have encountered a problem caused by packing Data.fs (pack done via ZMI - Control Panel - Database Management - main - Pack). After Data.fs is packed, the ZODBmount point for the zeo server is missing. I have the following folder set-up: Root |----Coz |---ZeoServer1 After the pack operation, folder 'ZeoServer1' is missing. In zope.conf I have: <zodb_db main> # Main FileStorage database <filestorage> path $INSTANCE/var/Data.fs </filestorage> mount-point / </zodb_db> <zodb_db zeo1> mount-point /Coz/ZeoServer1 # ZODB cache, in number of objects cache-size 5000 <zeoclient> server 192.168.123.1:8100 storage 1 name zeostorage var /apps/zeo1/var # ZEO client cache, in bytes cache-size 20MB # Uncomment to have a persistent disk cache #client zeo1 </zeoclient> </zodb_db> I am packing the main Data.fs (running on an application server - the zeo client) not the zeo Data.fs. (zeo server is running on a different machine). I am running Zope 2.9.2 on RedHat linux. Any ideas as to how to resolve this issue would be greatly appreciated! Jonathan
