 Managix associates a working directory with an ASTERIX instance and uses this directory for transferring binaries to each node. If there exists a directory that is readable by each node, Managix can use it to place binaries that can be accessed and used by all the nodes in the ASTERIX set up. A network file system (NFS) provides such a functionality for a cluster of physical machines such that a path on NFS is accessible from each machine in the cluster.  In the single-machine set up described above, all nodes correspond to a single physical machine. Each path on the local file system is accessible to all the nodes in the ASTERIX setup and the boolean value for NFS above is thus set to `true`.

-Notice that each machine has a ''cluster-ip'' address, which is used by these machines for their intra-cluster communication. Meanwhile, the master machine also has a ''client-ip'' address, using which an end-user outside the cluster can communicate with this machine.  The reason we differentiate between these two types of IP addresses is that we can have a cluster of machines using a private network. In this case they have internal ip addresses that cannot be used outside the network.  In the case all the machines are on a public network, the "client-ip" and "cluster-ip" of the master machine can share the same address.

 Next we describe how to set up ASTERIX in this cluster, assuming no Managix has been installed on these machines.
 
 ### Step (1): Define the ASTERIX cluster ###
 
-We first log into the master machine as the user "joe". On this machine, download Managix from [here](https://asterixdb.googlecode.com/files/asterix-installer-0.0.5-binary-assembly.zip) (save as above), then do the following steps similar to the single-machine case described above:

+##### Log Command #####
+
+The `log` command allows you to collect the log files coresponding to each node of an AsterixDB instance into a zip archive. 
+The zip archive is produced on the local file system of the machine running managix. 
+
+          $ managix help -cmd log
+        
+          Creates a zip archive containing log files corresponding to each worker node (NC) and the master (CC)  for an AsterixDB instance
+
+          Available arguments/options
+          -n name of the AsterixDB instance. 
+          -d destination directory for producing the zip archive. Defaults to $MANAGIX_HOME/logdump.
+         
+The following is an example showing the use of the log command. 
+
+         $ managix log -n my_asterix -d  /Users/joe/logdump

 ## Section 5: Frequently Asked Questions ##
 
 
-*Question*
-What is meant by the "UNUSABLE" state in the lifecycle of  an ASTERIX instance ?
+##### Question #####
+What happens if a machine acting as a node in the Asterix cluster becomes unreachable for some reason (network partition/machine failure) ?
 
+##### Answer #####
+When a node leaves the Asterix cluster, the AsterixDB instance transits to an 'UNUSABLE' state, indicating that it is no longer
+available for serving queries. To know which set of node(s) left the cluster, run the describe command with -admin flag. 
 
-*Answer*
-When Managix fails to start a required process (CC/NC), the instance transits to an UNUSABLE state.
-The reason for the failure needs to be looked up in the logs.
-Before we attempt to start the instance again, any processes that got launched
-as part of failed attempt must be stopped. No other operation except "stop" is supported in the UNUSABLE state.
+        $ $MANAGIX_HOME/bin/managix describe -n <name of the AsterixDB instance>-admin
+        
+Above command will show the state of AsterixDB instance and list the set of nodes that have left the cluster.           
 
-Get rid of the started processes:-
+The failed node must be brought back to re-join the cluster. Once done, you may bring back the 
+instance to an 'ACTIVE' state by executing the following sequence. 
+
+1) Get rid of the Asterix processes running on the nodes in the cluster:-
 
         $MANAGIX_HOME/bin/managix stop -n my_asterix
 
 
-Any processes associated with the instance are killed and the instance moves to the INACTIVE state.
-You may now delete the instance by executing the following
+The processes associated with the instance are terminated and the instance moves to the INACTIVE state.
+
+2) Start the AsterixDB instance using the start command.
+
+        $MANAGIX_HOME/bin/managix start -n <name of your AsterixDB instance>
 
 
-        $MANAGIX_HOME/bin/managix delete -n <name of your ASTERIX instance>
+##### Question #####
+Do I need to create all the directories/paths I put into the cluster configuration XML ?
+
+##### Answer ##### 
+Managix will create a path if it is not existing. It does so using the user account mentioned in the cluster configuration xml. 
+Please ensure that the user account has appropriate permissions for creating the missing paths. 
 
 
-Note that above would remove all traces of the instance including the logs and thus the reason for the failed attempt.
+##### Question ##### 
 
-OR
+Should MANAGIX_HOME be on the network file system (NFS) ?
 
-make a subsequent attempt to start the instance if you realized a mistake in the cluster configuration XML and have corrected it. To start the instance, we execute the following.
-
-
-        $MANAGIX_HOME/bin/managix start -n <name of your ASTERIX instance>
-
+##### Answer #####
+It is recommended that MANAGIX_HOME is not on the NFS. Managix produces artifacts/logs on disk which are not required to be shared. 
+As such an overhead in creating the artifacts/logs on the NFS should be avoided.
