comment Can't start mongodb in ArchLinux
I strongly recommend against using 32-bit platform for mongodb. As far as the error, you are starting mongod as some user, but you probably created the /data/db directory as another user. the permissions are such that mongod cannot create the files it needs. fix permissions.

comment Can't start mongodb in ArchLinux
even earlier there is indication that this is the wrong executable - you are on 64-bit architecture but this is a 32-bit mongoDB which is NOT suitable for production. Permission denied could just be that /data/db directory is owned by a different user than you are starting the mongod process as.

Did you try using localhost instead of 127.0.0.1?

comment How can I automate sharding in the presence of continuous reads
what exactly are the errors that you are getting from the readers that are caused by sharding in progress? Sharding operations should be transparent to the client in theory.

comment Does mongodb automatically move small non-partitoned databases to spread read load?
these seem like too small collections to be sharded. Have you considered moving them to separate mongod servers which can run on different machines? that gives you complete control over which are on which machines and keeps their indexes from fighting for the same RAM on the same machine...

comment MongoDB: Replica Set - master vs. slave
You need to use proper replica set configuration, not master/slave. See this page mongodb.org/display/DOCS/…

can you explain why you are thinking you want to store it in a separate db?

comment MongoDB: Replica Set - master vs. slave
correct, the drivers keep track of which is primary and send writes to that one (and reads unless you specify slaveOk for the read). And automatic failover happens as long as the majority of the replica set is up.
