4.7.3. 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.

Usage

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.

Example

In this example, the command sets the inherit_directio flag on the directory named /gfs1/data/. 
gfs_tool setflag inherit_directio /gfs1/data/
