The vxfs file system module automatically loads on the first reference to a VxFS file system; this occurs when a user tries to mount a VxFS file system.
In some instances, you may find it efficient to load the file system module manually. For example, some larger class systems can have many dual interface I/O cards with multiple disk chains attached. The device interrogation process when such a system is rebooted can be very time consuming, so to avoid doing a reboot, use the modprobe command to load the vxfs module:
# modprobe vxfs ; modprobe vxportal ; modprobe fdd
Do not use the insmod command to load the vxfs module as insmod does not examine the module configuration file /etc/modprobe.conf.
To determine if the modules successfully loaded, use the lsmod command as shown here:
# lsmod | grep vxportal vxportal 2952 0 vxfs 3427960 0 fdd vxportal # lsmod | grep fdd fdd 67212 0 (unused) vxfs 3427960 0 [fdd vxportal] # lsmod | grep vxfs vxfs 3427960 0 [fdd vxportal]
The first field in the output is the module name. You can unload the modules by entering:
# rmmod fdd # rmmod vxportal # rmmod vxfs
The rmmod command fails if there are any mounted VxFS file systems. To determine if any VxFS file systems are mounted, enter:
# df -T | grep vxfs
