When a network connection is reestablished. Noresvport – Tells the NFS client to use a new non-privileged Transmission Control Protocol (TCP) source port Retrans=2 – Sets to 2 the number of times the NFS client retriesĪ request before it attempts further recovery action. Wait for a response before it retries an NFS request to 600 deciseconds (60 seconds) to Timeo=600 – Sets the timeout value that the NFS client uses to Request times out, so that NFS requests are retried indefinitely until the server replies, ![]() Hard – Sets the recovery behavior of the NFS client after an NFS The NFS client can send for each network WRITE request to 1048576, the largest available, Wsize=1048576 – Sets the maximum number of bytes of data that The NFS client can receive for each network READ request to 1048576, the largestĪvailable, to avoid diminished performance. Rsize=1048576 – Sets the maximum number of bytes of data that Nfsvers=4.0 – used when mounting on supported EC2 Mac instances running macOS Big Sur, Monterey, and Ventura Nfsvers=4.1 – used when mounting on EC2 Linux instances ![]() The Amazon EFS mount helper client uses the following mount options that are For more information on how encryption works, see Data encryption in Amazon EFS. Using TLS requires certificates,Īnd these certificates are signed by a trusted Amazon Certificate Authority. The mount helper uses TLS version 1.2 to communicate with your file system. On a local port for inbound traffic, and the mount helper redirects NFS client traffic to this local port. Stunnel is an open-source multipurpose network relay. For clients running on a supported macOS, it is managed by launchd. If your client is running on Linux, this process is managed by either upstart or systemdĭepending on your Linux distribution. Process monitors the health of TLS mounts, and is started automatically the first time an EFS file system is mounted over TLS. System, the mount helper initializes a client stunnel process, and a supervisor process calledĪmazon-efs-mount-watchdog. When encryption of data in transit is declared as a mount option for your Amazon EFS file You can find the value for all of these properties in the Amazon EFS console. Mount target IP address – You can use the IP address of one of the file systems mount targets. Local IP address of the mount target elastic network interface (ENI) without calling external resources. Mounting EFS file systems from another AWS accountįile system ID – If you use the file system ID, the mount helper resolves it to the The /etc/fstab configuration file on EC2 Linux instances.įile system DNS name – If you use the file system DNS name,Īnd the mount helper cannot resolve it, for example when you are mountingĪ file system in a different VPC, it will fall back to using the mount target IP address. Supports mounting an Amazon EFS file system at instance boot time automatically by using entries in The mount helper defines a new network file system type, called efs, which isįully compatible with the standard mount command in Linux.
