I heard NFS is self-tuning in cluster-mode but am not sure how to (or we need to) tune things like window sizes in Cluster-Mode... Are there cluster commands for these, is it recommended to "node run options" to the dblade of every node or is it not best practice to modify these for cluster-mode like 7-mode?
Some examples of tuning done on may 7-mode installs
options cifs.tcp_window_size
options cifs.neg_buf_size
options cifs.max_mpx
options nfs.tcp.recvwindowsize
options nfs.tcp.xfersize
options nfs.ifc.xmt.high
options nfs.ifc.xmt.low
options nfs.sendq.max
