11.3.2.2 Tuning file system

In the GFS Shared File System, each file system can be tuned for the following items:

• Communication timeout value (CON_TIMEOUT)

• Communication protocol (SFCFS_IPV6)

Execute sfcadm(8) to change the above value on any one of the nodes where the file system is shared.

See

For details of sfcadm(8), see sfcadm(8).

The following example shows how to set the timeout value to 240 seconds for the existing file system (/dev/sfdsk/gfs01/volume01) using sfcadm(8).

# sfcadm -o CON_TIMEOUT=240 /dev/sfdsk/gfs01/dsk/volume01 <Enter>

See

For details about the tuning parameter, see "14.1.2 Communication timeout value" and "14.1.3 Communication protocol" in this manual.
