comment how to integrate between MONGODB & SOLR, using MONGO-CONNECTOR
auth is failing (per the error) - if you run without auth I assume it will work, so it would seem that you are either passing in the wrong credentials or the user is not valid to run the command - you mentioned that you started the shell, but did you try running a command (like rs.status()) to verify the user was logged in and valid?

comment Did my mongoDB server crash because the database is too large?
@Tim - mongodb has a max file size of 2GB for that reason (some FS/OS not supporting it) - it pre-allocates multiple files of 2GB (max, starts smaller) when databases exceed that size (see your data directory for database.0, database.1 etc.)

comment MongoDB and ZFS bad performance: disk always busy with reads while doing only writes
@jlliagre - yes, but as soon as you start actually changing the file you are going to see a performance hit, because you invalidate the whole lot

comment MongoDB and ZFS bad performance: disk always busy with reads while doing only writes
@AlexF - yes, basically - the server ticket I pointed to is the one that will fix that particular issue for ZFS on Linux. You can see a similar check for NFS here already, so it should not be a huge change, but there are likely to be other issues: github.com/mongodb/mongo/blob/v2.4/src/mongo/util/…

comment Why is mongod not using all available RAM?
If you take a look at the pieces related to under reporting of virtual memory you will note that it is possible for resident memory to be low, and not increase, but for data to be in memory. Pre-heat the data, then run a query, see if there are page faults when you know the data is in memory. You will probably need to quiesce the database to be sure about the measurement. If the secondaries are similarly spec'ed then do a failover and see what the behavior looks like then (this is what I meant about them all looking the same or not).
