UnixQuotas REG_DWORD 0 or 1
This parameter configures the restriction of disk space for “normal” UNIX users,
both for UNIX disk quota functionality and for using reserved disk space.
Specifies whether writing to files is performed under the UNIX user ID (UID) of the UNIX
system user to which the Advanced Server user is mapped.
Effects of the parameter on preserving the reserved disk area:
The files are written to under the UID of the relevant UNIX user. If this UID is not “0”, it
is not possible to write to the reserved disk space. The reserved disk space is then no
longer counted when displaying the free disk space.
Effects of the parameter on UNIX disk quota functionality:
Specifies whether Advanced Server provides UNIX system disk quota support. This
ensures that creating or writing to the file is performed under the UNIX system UID of
the UNIX system user to which the Advanced Server user is mapped. Each action
counts toward that user’s quota; an error message is sent to the client when the quota
is exceeded. Two quotas are supported: i-node and block quotas for UFS and NFS file
systems. This is true to the extent of the ability of these file systems to support UNIX
system quotas.
See also the chapter: “Restricting the user’s disk space” .
Default: 0 (no restriction of disk space)
The parameters UnixQuotas, IgnoreUnixPermissions and UnixDirectoryCheck
depend on each other in the following way:
– If UnixQuotas is set to 1, the other two parameters are both assumed to be 0
independent of their real registry values.
– If UnixQuotas is set to 0 and IgnoreUnixPermissions is set to 1, the parameter
UnixDirectoryCheck is assumed to be 2 independent of its real registry value.
UseEAs REG_DWORD 0 or 1
Specifies support for OS/2 extended attributes.
Default: 0 (no support for extended attributes)
UseNfsLocks REG_DWORD 0 or 1
Specifies whether the server tries to set UNIX system record locks in files as requested
by clients. Record locks may not work on NFS files on a server running NFS. If the value
of the UseUnixLocks key is 0, this feature has no effect on the server.
Default: 0 (do not set locks)
