Nfs Locks; Nfs Async/Sync Settings Page - HP ProLiant 300 Series Administration Manual

NOTE:
Using synchronous writes allows for greater data integrity. Asynchronous writes will increase performance
but will reduce data integrity as the data is cached before being written to disk. Changing the write state
causes the NFS service to be restarted. Notify users before toggling this setting.

NFS locks

NFS supports the ability to lock files. File locking helps prevent two or more users from working with the
same files at the same time.
NFS locking depends on the software application components to manage the locks. If an application
does not lock a file or if a second application does not check for locks before writing to the file, nothing
prevents the users from overwriting files.
To enter locking parameters:
1. From the WebUI, access the NFS Protocol Properties page by clicking Shares, Sharing
Protocols. Select NFS Protocol, and then click Properties.
The NFS Properties menu is displayed.
2. In the NFS Properties page, click NFS Locks.
The NFS Locks page is displayed. (See
All clients that have locks on system files are listed in the Clients that hold locks box.
3. To manually clear locked files, select the client from the displayed list, and then click OK.
4. To indicate the amount of time after a system failure that locks are kept active, enter the number of
seconds in the Wait period box.
