Description sthirugn@redhat.com 2019-06-25 18:56:45 UTC

Section Number and Name:
N/A

Describe the issue:
The mongo upgrade to WiredTiger storage engine (which is faster than older storage engines) should be documented in both Satellite and Capsule upgrade guides.

To upgrade to mongo WiredTiger, run the installer command as shown below after upgrading to Satellite 6.5.

satellite-installer --upgrade-mongo-storage

Note that this process requires the above installer command to storage the mongodb contents in /var/tmp temporarily.  Please make sure that /var/tmp has enough or more space than the size of /var/lib/mongodb.

Suggestions for improvement: 

Additional information: 
- Note that Satellite 6.4 and Satellite 6.5 get WiredTiger storage engine by default on new installations.
- Currently, the upgrade of storage engine to WiredTiger is supported *only* on Satellite 6.5. This capability for 6.4 will be available when BZ 1715227 is fixed.

Correction:
The actual command is `satellite-installer --upgrade-mongo-storage-engine`
