This command supplies the system administrator with information on which file systems in POSIX are affected by the export of a pubset and must therefore be unmounted before the EXPORT-PUBSET command is executed.
This information is particularly helpful when bs2fs file systems are used. Unlike with the ufs and NFS file systems, it is not sufficient in this case to check whether the mount point of a file system is located on the pubset concerned.
With bs2fs file systems the location of the BS2000 files mounted by means of bs2fs is also relevant. The mount point of the bs2fs container also plays a role. If it is located on the pubset to be exported, all mounted bs2fs file systems are affected by the export, irrespective of their location.
Depending on the file system type, a file system is affected by EXPORT-PUBSET, if the objects shown in the following list are located on the pubset to be exported:
ufs:
Mount point or container file
nfs:
Mount point
bs2fs:
Mount point or mounted BS2000 files or mount point/container file of the bs2fs container (cf. ufs)
Syntax
show_pubset_export cat-id |
cat-id Catalog ID of the pubset which is to be checked (without enclosing colons “:”). The entry can be made in upper- or lowercase notation or a mixture of both; the check is performed with the cat-id converted to uppercase notation. |
File
The following files are searched for the specified catalog ID in order to determine the file systems affected: /etc/mnttab Table of all mounted file systems /etc/partitions Table of all possible partitions SYSSSI.POSIX-BC.<version> SYSSSI file of POSIX from BS2000 |
Example
The file systems affected by the export of the DATA pubset are determined. The container file of the ufs file system mounted under the home directory /home/bach resides on the DATA pubset.
