How to: Manage Mounted NFS Shares¶
NFS allows the ability to mount remote filesystem. This allows the user to have data stored on a remote server, and access that data, locally.
From the Mounts page in NodeWorx, server administrators can add and remove mounted NFS shares.
To Add a Mounted NFS Share¶
Log into NodeWorx from the browser (https://ip.ad.dr.ess:2443/nodeworx)
In NodeWorx, navigate to System Services > NFS Server > Mounts
Under Add Mounted Filesystem, update the relevant fields:
Host: The IP or hostname of the machine that contains the NFS share that will be mounted
Remote Directory: The full path of the remote directory to be mounted
Mount Point: The local mount point the remote directory will be available on. This must be an existing directory. When mounting to a directory, any subdirectories or files in that directory become hidden and inaccessible while there is something mounted on that directory. As such, it is recommended to use an empty directory for a mount point
Protocol: The mount protocol determines which IP data transmission protocol the NFS server and client will use to communicate. Typically, TCP is recommended because it is able to account for lost packets, as well as packets arriving out of order
Mount Type: The mount type determines how the client reacts in the event of a failure:
Hard: Forces the program to wait until the server comes back online
Soft: Reports an error to the program, and allows it to continue execution
Re-Mount Options: Determines the behavior of the system to remount the share when there is an error:
Halt: Indicates that the share should be dropped from the mount table
Continue: Indicates that the share should remain mounted, as it could just be a temporary failure
Interrupt Handling: How interrupts for file operations will be handled. This functions in combination with the hard mount type:
Interrupt: If the connection for a hard mount type drops, allowing interrupts gives the ability to interrupt the operation that is waiting on the connection to resume, and allows the program to continue
Do Not Interrupt: Processes that are waiting on I/O on the NFS share will be unable to execute until the NFS export comes back online, or the NFS client is restarted
