3.8.3. GFS Directory Attribute
The gfs_tool command can be used to assign (set) a direct I/O attribute flag, inherit_directio, to a GFS directory. Enabling the inherit_directio flag on a directory causes all newly created regular files in that directory to automatically inherit the directio flag. Also, the inherit_directio flag is inherited by any new subdirectories created in the directory. The inherit_directio flag can also be cleared.
Setting the inherit_directio flag
gfs_tool setflag inherit_directio Directory
Clearing the inherit_directio flag
gfs_tool clearflag inherit_directio Directory
Directory
Specifies the directory where the inherit_directio flag is set.
In this example, the command sets the inherit_directio flag on the directory named /mnt/gfs/data.
gfs_tool setflag inherit_directio /mnt/gfs/data
This command displays the flags that have been set for the /mnt/gfs/data directory. The full output has been truncated.
[root@tng3-1 gfs]# gfs_tool stat /mnt/gfs/data
