Associate New
Directories with Files
Files can be present in a directory when the fsaddrelation
is performed.
Creating a directory under a directory that is an association
point automatically associates the newly created directory with
the DataClass group of its parent directory.
Returned status shows that the file system is busy. A file system
must be inactive because it must be unmounted, mapped, and
remounted at the time of the fsaddrelation to ensure that
associated file information is accurate upon completion.
The file system is mapped by unmounting the file system and
remounting it exclusively for the mapping process. It is
recommendedtoperformthe
fsaddrelation to a populated
directory during a slack time. Users cannot access any files in
the file system during the fsaddrelation processing.
Following the mapping and execution of the
fsaddrelation
operation, the file system is unmounted and remounted to allow
user access again.
Because the
fstat options are limited, list all open files and
grep the major and minor device numbers of the file system to
check for users. On SGI systems, the user can run the
fuser
command to find the same information.
Note
When adding a DataClass relation to a directory that contains
files, no users are allowed in the file system at the time the
command is issued or the command fails.
Note
For more information about major and minor device numbers,
refer to the manual page for the UNIX fstat or fuser
commands.
