Percona is pleased to announce the release of Percona Server for MongoDB 3.0.8-1.3 on February 24, 2016. Download the latest version from the Percona web site or from the Percona Software Repositories.
Percona Server for MongoDB is an enhanced, open source, fully compatible, highly scalable, zero-maintenance downtime database supporting the MongoDB v3.0 protocol and drivers. Based on MongoDB 3.0.8, it extends MongoDB with MongoRocks and PerconaFT storage engines, as well as features like external authentication and audit logging. Percona Server for MongoDB requires no changes to MongoDB applications or code.
NOTE: MongoRocks has been labeled experimental. This is not related to any changes, it is a reminder that the storage engine is still under development. There is currently no officially released version of MongoRocks that can be recommended for production.

If you did not manually modify the defaults file before upgrading, the installer should correctly replace the defaults file. Otherwise, add the
STDERR variables after you install the new version of Percona Server for MongoDB.
On Ubuntu 14.04 LTS (Trusty Tahr), the post-install script cannot correctly start
stderr not directed to
/dev/null. To enable the new logging functionality, you need to add the
-C option to the
start-stop-daemon command in
/etc/init.d/mongod. The line that starts
mongod should look similar to the following:
start-stop-daemon -C --background --start --quiet --pidfile $PIDFILEPATH
After you make necessary changes to the script, restart the daemon:
$ service mongod restart
- Changed the default value of the
processManagement.fork parameter in
true. This does not affect normal operation, only PID tracking in the OS.
Before upgrading on Debian 8 (“jessie”), Ubuntu 15.04 (Vivid Vervet), or Ubuntu 15.10 (Wily Werewolf), you will need to manually change the
processManagement.fork parameter to
- PSMDB-30: Added SELinux support for Red Hat Enterprise Linux and CentOS.
- PSMDB-39: Fixed issue that caused incorrect behavior during hot backup when the
--logpathoption was set.
