![]() ![]() and there is a small triangle next to it, click down to expand.Ģ) Notice there is a "DNS Name" right in the middle of the screen, it will say something like: ".com", note that down, this is your mounting point that we will use later on.ģ) By default, if you have just created the new instance, then you must allow it to be seen by your servers, trying to connect will freeze since the firewall is blocking your connection. On your AWS account, notice the following:ġ) Go to your EFS management screen, you should your EFS_WHATEVER. To solve this using NFS4, please follow the instructions below: Once you have the mount client software installed, use the corresponding mounting instructions posted above. On an Ubuntu instance, use this command: sudo apt-get install nfs-common On a Red Hat Enterprise Linux or SUSE Linux instance, including Amazon Linux, use this command: sudo yum install -y nfs-utils If you want to use "NFS client", use the following installation instructions on your EC2 instance: If you want to use "Amazon EFS mount helper", use the following installation instructions for Amazon Linux and Other Distros: Installation instructions for mount client software: "NFS client" nfs4 in both CLI and /etc/fstab ![]() ![]() ![]() "Amazon EFS mount helper" efs in both CLI and /etc/fstab To solve the problem, you can use either Amazon EFS mount helper ( amazon-efs-utils) or NFS client ( nfs-utils), but the command format (in CLI or /etc/fstab) and the mount client being used should be consistent. If you were using "Amazon EFS mount helper", the -t parameter should be efs. Notice the -t parameter above is nfs4, which is the format for "NFS client". The manual mount command you posted above that worked for you is only for "NFS client", not for "Amazon EFS mount helper". Since your system doesn't have "Amazon EFS mount helper" installed, it doesn't understand the auto mount format inside /etc/fstab so auto mount it doesn't work for you. You were using "Amazon EFS mount helper" format inside /etc/fstab to auto mount, but the manual mount command that worked for you is in "NFS client" format. You thought you've "Amazon EFS mount helper" installed, but based on the manual mount command format you posted in your first comment reply (not opening post), you actually only have "NFS client" installed on your system. Given the above example format, do you notice your problem? :/ /path/to/mount/dir nfs4 defaults,_netdev 0 0 To mount with "NFS client" automatically, you insert the following line into /etc/fstab. OR sudo mount -t nfs4 -o defaults,_netdev. sudo mount -t nfs4 -o nfsvers=4.1,rsize=XXXXXXX,wsize=XXXXXXX,hard,timeo=XXX,retrans=X,noresvport. Use the command instruction given from "Amazon EC2 mount instructions (from local VPC)" when you click in to view the Elastic File System ID in question under EFS Web Console. To mount with "NFS client" manually, you issue either of the following command format into CLI: To mount with "Amazon EFS mount helper" automatically, you insert the following line into /etc/fstab :/ /path/to/mount/dir efs defaults,_netdev 0 0 To mount with "Amazon EFS mount helper" manually, you issue the following command format into CLI: sudo mount -t efs :/ /path/to/mount/dir Before using, replace the text with your own values. There are two methods to mount an Amazon EFS: "Amazon EFS mount helper" ( amazon-efs-utils) and "NFS client" ( nfs-utils).Įxamples below shows how to mount manually and automatically with each method. I'm posting here a more detailed solution since this thread seems to show up near the top for related queries from search engine. ![]()
