Description
Before 4.2 MMAPv1 options used with WT were just ignored.
In 4.2 the server won't start if MMAPv1 options are used:
Error parsing command line: unrecognised option '--smallfiles'
|
try '/bin/4.2.0/mongod --help' for more information
|
We should document that in the release notes
Scope of changes
- Add a blurb to the 4.4 release notes on MMAPv1 removal. Spitballing:
"4.4 mongod or mongos cannot start with MMAPv1 options specified to the command line or configuration file "
- Add blurb to 4.0 -> 4.2 upgrade notes reminding users to remove MMAPv1 options from the command line or configuration file as part of upgrade
- Upgrade note needs to be in master and 4.0.
