Mount nfs helper program

To un-mount the NFS mount point you can just use umount command followed by the mount point path. So either you can find and kill that process or let the process complete.

You can use. Now since you know the process which is occupying your NFS mount point, you can either choose to kill it or let the process complete. If you choose to ignore the PID and want to let it complete, how would you know when the process is complete? SO to overcome this we have something called lazy un-mount where we can trigger umount with -l or --lazy , for example:. So this will detach the file system from the file system hierarchy now, and cleanup all references to the file system as soon as it is not busy anymore.

The recommended use-case for umount -l is to prevent hangs on shutdown due to an unreachable network share where a normal umount will hang due to a downed server or a network partition.

In this tutorial we learned about methods to mount NFS shares on client nodes. The only difference would be the NFS client package to be installed. Welcome to Unix.

NFS version 3 NFSv3 supports safe asynchronous writes and is more robust at error handling than the previous NFSv2; it also supports bit file sizes and offsets, allowing clients to access more than 2 GB of file data. Sparse files Enables files to have one or more holes , which are unallocated or uninitialized data blocks consisting only of zeroes. The lseek operation in NFSv4. Space reservation Permits storage servers to reserve free space, which prohibits servers to run out of space.

Enhances performance and security of network, and also includes client-side support for pNFS. No longer requires a separate TCP connection for callbacks, which allows an NFS server to grant delegations even when it cannot contact the client: for example, when NAT or a firewall interferes.

Provides exactly once semantics except for reboot operations , preventing a previous issue whereby certain operations sometimes returned an inaccurate result if a reply was lost and the operation was sent twice. These ports are then made available or advertised so the corresponding remote RPC services can access them. This is not used with NFSv4. It checks that the requested NFS share is currently exported by the NFS server, and that the client is allowed to access it.

It works with the Linux kernel to meet the dynamic demands of NFS clients, such as providing server threads each time an NFS client connects. This process corresponds to the nfs-server service.

The rpc-statd service is started automatically by the nfs-server service, and does not require user configuration. The rpc-rquotad service is started automatically by the nfs-server service and does not require user configuration. Additional resources Configuring an NFSv4 only server without rpcbind.
