Tuneable parameters are updated at the time of mount using the tunefstab
file or vxtunefs
command. The file system tunefs
parameters are set to be identical on all nodes by propagating the parameters to each cluster node. When the file system is mounted on the node, the tunefs
parameters of the primary node are used. The tunefstab
file on the node is used if this is the first node to mount the file system. Symantec recommends that this file be identical on each node.
