VxFS caches inodes in an inode table. The tunable for VxFS to determine the number of entries in its inode table is vxfs_ninode.
VxFS uses the value of vxfs_ninode in /etc/modprobe.conf
as the number of entries in the VxFS inode table. By default, the file system uses a value of vxfs_ninode, which is computed based on system memory size. To increase the value, make the following change in /etc/modprobe.conf
and reboot:
options vxfs vxfs_ninode=new_value
The new parameters take affect after a reboot or after the VxFS module is unloaded and reloaded. The VxFS module can be loaded using the modprobe command or automatically when a file system is mounted.
