Recently, it seems my NFS connections have been crashing hard, most recently, a saved file from my browser to my servers’ mount point via NFS which caused the VM I was using to completely lock up:( So I did some quick searching and found these options which you should use when mounting any NFS shares:
If the first NFS mount attempt times out, retry the mount in the background. After a mount operation is backgrounded, all subsequent mounts on the same NFS server will be backgrounded immediately, without first attempting the mount. A missing mount point is treated as a timeout, to allow for nested NFS mounts.
If an NFS file operation has a major timeout then report an I/O error to the calling program. The default is to continue retrying NFS file operations indefinitely
If an NFS file operation has a major timeout and it is hard mounted, then allow signals to interupt the file operation and cause it to return EINTR to the calling program. The default is to not allow file operations to be interrupted.
and to deal with timeouts:
Thanks stackexchange peoples:)
