NAS Configuration CLI Commands
35
This CLI command enables or disables LDAP client signing. This setting must
be enabled if and only if the LDAP server signing is enabled on the ADS
server. Otherwise, it must be disabled. For more information on how to
enable LDAP server signing on the ADS server, see Microsoft documentation
at: http://support.microsoft.com/kb/935834
• syscli –maxprocesses <max_smbd_processes>
This CLI command changes the maximum number of smbd processes at any
given time. By default, the limit is 100.
•
syscli --clientntlmv2auth yes|no
This CLI changes “client NTLMv2 auth” setting to yes or no. By default, this
setting is set to “yes” and must not be changed unless the domain group
policy on the ADS is set to use the older NTLM (v1) exclusively.
• syscli -- serversigning disabled|enabled
This CLI Changes “server signing” setting to “disabled” (disabled) or “auto”
(enabled).
Commit NFS
Synchronously
syscli --nfscommit sync {--share <sharename>} | --all
This CLI command allows the admin user to set up NFS shares so that data are
committed synchronously to NFS shares. When using the synchronous setting,
all data that is to be written must be committed to physical storage, and all the
data must be written to that storage before the system will accept
stable
write
or
commit
commands. This ensures that when a backup completes all
the data resides on disk. This setting can be altered through the CLI. The user
can set up this property for one NFS share at a time or all NFS shares at the same
time. By default, NFS shares are created to commit data synchronously.
NFS Commit
is an NFSv3 client call to request the NFS server to commit cached
data to stable storage. The server has two choices:
a Accelerated mode:
This option allows the NFS server to violate the NFS
protocol and reply to commit requests before cached data is committed
to stable storage. This mode improves I/O performance but may cause
data inconsistencies in case of power failure or severe interruptions.
b Standard mode:
Honor the NFS commit calls truthfully by committing
cached data to stable storage before responding to the clients. This
mode guarantees data integrity in case of power failures or severe
interruptions.
This CLI command sets up NFS server to run in
Standard mode
, with NFS
commits synchronously between server and client.
Commit NFS
Asynchronously
syscli --nfscommit async {--share <sharename>} | --all
This CLI command allows the admin user to set up NFS shares so that data are
committed asynchronously to NFS shares. When using the asynchronous
setting, the system will allow receipt of
stable
write
or
commit
commands
without having the data (and related metadata) fully written to disk. This mode
allows backups to be completed faster (from the backup application point of
view); however, there is the possibility of having an incomplete backup if the
