added to release notes: <quote> GFS for Red Hat Enterprise Linux 4 Update 5 now includes the df command, which significantly improves the execution time of the statfs call. This option uses cached information for the calculation of used space. For the majority of users this is sufficiently accurate. To use the Fast statfs option, start by issuing the following command on each node: gfs_tool settune <mount point> statfs_fast 1 This command must be run after mount. Note that Fast statfs is not persistent after an unmount. It is recommended that you use a wrapper script to perform the mount then set the flag. Setting the flag can be integrated into the gfs init script in /etc/init.d/gfs. Fast statfs can also be turned off for mounted volumes. To do this, issue the following command on all nodes: gfs_tool settune <mount point> statfs_fast 0 </quote> Adding 'cc ecs-dev-list for team coverage Content is available in release notes here: http://www.redhat.com/docs/manuals/csgfs/release-notes/CS_4-RHEL4U5-relnotes.html Removing automation notification |
