Dell PowerVault 775N (Rackmount NAS Appliance) - Manual (Page 90)

Table 10-3. UNIX and Red Hat Linux
Issue Possible cause Resolution
I cannot access
the NAS
Manager from
my Red Hat®
Linux client
system.
The NAS Manager is not supported by the Red Hat Linux operating system and does
not work with the NAS Manager.
Use a client system
running Windows to
connect to the NAS
Manager.
While updating
client access to
an NFS share,
the No Access
option is
displayed, but
the Root
option is not.
Only the All Machines category options are displayed during this update. Add the appropriate
client systems, and
then select OK. After
you have added the
client system,
navigate back to the
NFS tab for this
share and select the
correct options for
the individual Client
Machines.
Every time I
try to obtain a
directory listing
from an NFS
client on the
root of a
system
volume, I get
an error
message, such
as Permission
Denied
.
The problem you are experiencing involves a System Volume Information
directory created by Microsoft Index Server. The NFS service does not have access
to this directory and returns an error message to the client when trying to list its
properties.
This issue only occurs when sharing the root of a drive letter.
Ignore this error.
The System
Volume
Information
directory is not used
by NFS clients or
your system by
default.
Sometimes I
am unable to
delete folders
that have been
used and that
are shared to a
client system
that is running
NFS.
This situation occurs with NFS discretionary access lists (DACLs) and inheritance.
When the folder to be shared is created, the only access control entry (ACE)
created by default is Everyone with Full Control. When an NFS client creates a
directory or a file in this directory (mounted share), Services for UNIX® (SFU)
creates a new DACL that replaces the inherited Everyone with Full Control ACE.
This DACL contains an Everyone ACE with the appropriate UNIX file creation access
and may contain two other ACEs for the mapped user and group. If this happens,
the administrator of the client system that is running Windows cannot delete the file
or directory unless that administrator takes ownership through the client system
that is running Windows and changes the access.
As the administrator,
use a client system
running Windows to
take ownership and
change the access to
allow yourself to
delete the share
folders.
When you delete the
NFS share folders,
ensure that there are
no open file handles
for the share. If you
are unsure, delete
the share, and then
restart NFS.
When updating
the client
system's
access to an
NFS share, the
All Machines
client group is
reset from the
No Access
access type to
Read-Write
access.
The NAS Manager might reset the All Machines client system's group to Read-
Write when the client systems do not have read-only or read-write access.
Add a client system
that has read-write
or read-only access,
and then set the All
Machines client
system group to No
Access.
My NAS
system is
NFS write-back cache is disabled. If your system is not
part of a cluster, you
