ReadOnly status3
indicates whether the fileset is mounted for read-only access:
DescriptionValue
The fileset has read and write access.FALSE
The fileset is mounted for read-only access.TRUE
This field is displayed only if the fileset is in the STARTED state.
NFSTimeout time4
is the number of seconds that the OSS name server retains the results of nonretryable Network
File System (NFS) operations for the fileset.
This field is displayed only if the fileset is in the STARTED state.
NFSPool number1
is the number of kilobytes that the OSS name server uses for buffers for nonretryable NFS
operations for the fileset.
This field is displayed only if the fileset is in the STARTED state.
NFSPermMap PermMap-value
(J06.09 and later J-series RVUs or H06.20 and later H-series RVUs only) Specifies how the
permissions for an OSS object protected by optional access control list (ACL) entries are mapped
to the permissions (rwxrwxrwx) used by Network File System Version 2 (NFS V2) clients on
open, read, write, and directory search operations. Write permissions are always enforced
on the NonStop server using the actual standard OSS permissions or OSS ACL permissions (if
present) on the object. The attribute values for NFSPERMMAP are:
DescriptionValue
The other and owning group fields of the permissions bits returned to NFS V2 clients are
modified such that only access that would be granted to everyone in the ACL, excluding
the owner, is granted in the permissions bits. That is:
RESTRICTIVE
• The ACL entries for the class mask, the owning group, and all optional users are
examined. The group permissions returned to NFS V2 clients for this object are the
most restrictive of the permissions bits of these ACL entries.
• The ACL entries for the class mask, the owning group, other, all optional groups,
and all optional users are examined. The other permissions returned to NFS V2 clients
for this object are the most restrictive of the permissions bits of these ACL entries.
Setting NFSPERMAP to this value can cause some users on NFS V2 clients to be denied
access to objects to which they should legitimately be granted access according to the
OSS ACL on the NonStop server.
The other and owning group fields of the permissions bits returned to NFS V2 clients are
modified such that access that would be granted to anyone in the ACL, excluding the
owner, is granted in the permissions bits. That is:
PERMISSIVE
• The ACL entries for the class mask, the owning group, and all optional users are
examined. The group permissions returned to NFS V2 clients for this object are the
most permissive of the permissions bits, as allowed by the class mask, of these ACL
entries.
• The ACL entries for the class mask, the owning group, other, all optional groups,
and all optional users are examined. The other permissions returned to NFS V2 clients
for this object are the most permissive of the permissions bits for the other ACL entry
and, as allowed by the class mask, the ACL entries of the owning group, optional
groups, and optional users.
Setting NFSPERMMAP to this value guarantees that users who have read permission in
the OSS ACL for an object on the NonStop system will be able to read the object on
NFS V2 clients. However, it also allows users on NFS V2 clients who do not have read
