Upgrade to Ubuntu 15.04 from 14.10 breaks mongo - how to fix?

Question

I made the mistake yesterday of upgrading to 15.04 :-). Now my mongod can't start:

MongoDB shell version: 2.6.9
connecting to: test
2015-04-26T08:45:08.339-0600 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2015-04-26T08:45:08.339-0600 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed

sudo service mongod status

● mongod.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

So next, I searched for the lock file related to mongodb and removed it. - no help. So next I did:

sudo -u mongodb mongod --repair --dbpath /var/lib/mongodb/
sudo service mongodb start

 sudo -u mongodb mongod --repair --dbpath /var/lib/mongodb/

joel@Parke:/var/lib/mongodb$ sudo service mongodb start
Failed to start mongodb.service: Unit mongodb.service failed to load: No such file or directory.

Still no help. So next I created a /data/db directory in the hopes that this might work -- no go.... So any ideas? I assume this is related to the move away from upstart?

Thanks...

Answer 1

For others that run across this - what a pain! It turns out that Mongo>2.6.3 has a known issue with start: Support Systemd (cannot start mongodb with init scripts with Fedora 15 or above) As noted here: https://jira.mongodb.org/browse/SERVER-17742 and it seems that this possibly won't be fully fixed for >2.6.3 until Ubuntu 16.04, unless there is a strong outcry.

So the solution for me was to issue:

sudo apt-get install --reinstall mongodb

This reverted back to mongo 2.6.3 and NOW ALL WORKS! For those that run across this... Thanks to all who looked at this!
