Question

My server went down from an electrical failure and for a few horrifying seconds, I thought I’d lost all MongoDB data. I then realized that when the server restarted, mongo automatically restarted without the –dbpath option.

What I can’t figure out is why, even though my mongodb.conf has the dbpath set to /var/lib/mongodb, mongo looked for the db files in /data/db on startup. Can anyone shed some light on this?

Thanks!

/data/db is the default path that mongod will look for data files in if it is started with no options. Does your startup script instruct mongod to load the correct config file? If not, that would explain this behavior.
