No primary detected for set cnf-serv about mongo-cluster-docker HOT 8 CLOSED

Hi,

based on log it looks like Docker have no access to scripts files during setup first Replica Set called mongo-cnf-setup_1 .

mongo-cnf-setup_1    | standard_init_linux.go:178: exec user process caused "no such file or directory"

I know two Docker related reasons for that:

1. check line-ending in those files init_shard.sh, setup.sh, setup_cnf.sh - the patch is prepared #4 or change them manually to LF, also global git config can mess this up - for example autocrlf=true
2. add your disk to Shared Drives in Docker - https://forums.docker.com/t/volume-mounts-in-windows-does-not-work/10693/9

Drop me a line, if this covers your case. Cheers.

I think changing the lines to LF did the trick. Noob question, which instance should I use as the master from my app? mongo1-1 ? Thanks!

Now it's working. Apparently I had to open it with sudo -i. My apologies.

Thank you!

I would use mongo-router as main entry point from read and write concern. It is a little bit confusing, because in this setup I use both Replication and Sharding together.

You could think about this like RAID 1+0. I've purposefully avoided to called any node master, because Mongo don't have multi-master https://docs.mongodb.com/manual/core/master-slave/.

Whole set is sharded environment, that's why on any databases and any collection you can create setup to share/split data across different ReplicaSets.

Additionally mongo-1-1 is main entry point for ReplicaSet1 and mongo-2-1 is main entry point for ReplicaSet2. Each ReplicaSets can elect their master and act as a fallback (with additional help from connection string options).

For more info, please referrer to https://docs.mongodb.com/manual/sharding/

Clear as water. Thank you very much! I'm still learning replicating and sharding, and this is an excellent resource. Cheers

i'm having the same issue again, but this time using elementary OS (16.04). Tried changing the files to LF but it didn't work. Do I need to mount any volumes? and if so, how could I do it?

Thanks for the help so far

Do you have +x chmod on scripts ?
