Hey there,
I am trying to update a sharded cluster from 4.2.7
to 4.4.0
.
So far I have updated the config
and shard
replica sets without any issue.
But when updating the mongos
instances I get the Following exception:
{"t":{"$date":"2020-08-17T20:48:55.000+00:00"},"s":"F", "c":"CONTROL", "id":4757800, "ctx":"ftdc","msg":"Writing fatal message","attr":{"message":"DBException::toString(): NonExistentPath: \"/dev/stdout.diagnostic.data\" could not be created: Permission denied\nActual exception type: mongo::error_details::ExceptionForImpl<(mongo::ErrorCodes::Error)29, mongo::AssertionException>\n"}}
My systemLog
config looks like this:
systemLog:
destination: file
logAppend: true
path: /dev/stdout
I am using /dev/stdout
as I am running my mongod and mongos instances within docker containers. From the exception it seems that mongo is trying to create a file at /dev/stdout.diagnostic.data
which obviously doesn’t work. Not sure what changed between 4.2.7
and 4.4.0
that broke this for me, as the only thing I have changed in my configuration is the mongo server version.
Anybody any insight on how to fix this?
