Celerra Network Server Command Reference Manual
The server Commands
[nonotify]
Turns notify off. When on (default), the notify option informs the
client of changes made to the directory file structure.
[nooplock]
Turns oplocks (opportunistic locks) off. When oplocks are on
(default), they reduce network traffic by enabling clients to cache
the file and make changes locally. To turn Windows oplocks off,
unmount the file system, then remount with nooplock.
[notifyonaccess]
Provides a notification when a file system is accessed. By default,
notifyonaccess
is disabled.
[notifyonwrite]
Provides a notification of write access to a file system. By default,
the notifyonwrite option is disabled.
[noscan]
Disables the Virus Checker protocol for a file system. The Virus
Checker protocol is enabled using
server_setup and managed by
server_viruschk .
[uncached]
Allows well-formed writes (i.e., multiple of a disk block and disk
block aligned) to be sent directly to the disk without being cached
on the server.
[cifssyncwrite]
Performs an immediate synchronous write on disk independently
of CIFS write protocol option. This can impact write performance.
[triggerlevel=<value>]
Specifies the deepest directory level at which notification occurs.
The default is 512. The value -1 disables the notification feature.
[ntcredential]
Enables the Celerra Network Server to take full account of a
user’s Windows group memberships when checking an ACL for
access through NFS. When a UNIX user intiates a full request for
a file system object, the UNIX UID is mapped to the Windows
SID, then merges the user’s UNIX and Windows groups together
to generate a Windows NT Credential. This applies to NT,
SECURE
, MIXED and MIXED_COMPAT access-checking
policies.
