[Pulp-list] FW: Problem starting pulp-server - think it's relating to mongodb...

Tue Jan 25 19:46:40 UTC 2011

Stephen,

The mongodb rpm packaged in EPEL has a defect.  It fails to create /var/lib/mongodb and so 
mongod will not start.  The rpm you downloaded /may/ have the same issue.  I suggest you 
verify the directory exists and accessible by the mongodb user.

If not:

# mkdir /var/lib/mongodb
# chown mongodb /var/lib/mongodb
# chgrp mongodb /var/lib/mongodb

Hope this helps.
