This option enables you to change, extend and delete existing POSIX file system entries and to generate new POSIX file system entries.

Figure 26: Follow-up mask for “Administrate POSIX filesystems”
The follow-up mask lists all the BS2000 files that are registered in the POSIX subsystem as local container files. Use “+” and “-” to browse through the list.
Each entry contains:
the BS2000 file name of the container file
the size of the container file in PAM pages (unit: 2 Kb)
the current setting of the following parameters:
FS= File system inside (y/n),JO= Journaling (y/n),The function "Journaling" is no longer supported, i.e. the column JO is meaningless.
AM= Automount (y/n) andPF= POSIX file system marker (y/n)
The bottom line contains a selection field (“command”) where you can enter any of the following administrative commands.
‘a‘=append
Create a new entry
Add a container file and, if necessary, a file system to the list. Beforehand, mark the entry after which you want to add the new entry; otherwise the new entry will be appended to the end of the list.
When a file system is created with the append function, the system administrator has the choice of marking the file system as “created by POSIX“ (i.e. as an EBCDIC file system) or not (ASCII file system). The root and var file system are automatically tagged “created by POSIX” on initial installation.
‘m‘=modify
Modify marked entry
You can subsequently modify specific fields of the file system.
‘d‘=delete
Delete marked entry
Only the marked entry is removed from the list. The container file and the file system remain unchanged and can be entered again or deleted later.
‘e‘=expand
Expand marked file system
This command enables you to expand the selected file system, provided it can be unmounted. When this command is entered the same mask is displayed as with the option “Expand POSIX filesystems”.
In contrast to offline mode, the following applies here:
The root and var file systems cannot be expanded here as they are always occupied and cannot be unmounted.
The BS2000 filename field already contains the name marked in the BS2000 POSIX filesystem table mask and cannot be modified.
After successful expansion and after you have pressed F2, the file system is remounted if it was not mounted before the expansion. This is the case regardless of the Automount setting.
After you have pressed F2 the program returns to the previous mask BS2000 POSIX filesystem table.
