To automatically mount a EFS volume after each reboot, you’ll need to add the following format to /etc/fstab.
You can use the DNS name given by AWS.
fs-12345678:/ /mnt/efs efs defaults,_netdev 0 0 |
fs-12345678:/ /mnt/efs efs defaults,_netdev 0 0
Or the IP address.
10.0.0.22:/ /mnt/efs efs defaults,_netdev 0 0 |
10.0.0.22:/ /mnt/efs efs defaults,_netdev 0 0
Mount all with fake and verbose.
mount -fav |
mount -fav
Here’s how to display mount targets of an EFS system via AWS CLI.
aws efs describe-mount-targets \ --file-system-id fs-xxxxxxxx \ --profile default \ --region us-east-1 |
aws efs describe-mount-targets \ --file-system-id fs-xxxxxxxx \ --profile default \ --region us-east-1
Here’s how to fix a duplicate UUID on a XFS file system.
mount -o rw,nouuid /dev/sda1 /data |
mount -o rw,nouuid /dev/sda1 /data
Mounting with nouuid will work, but not after a reboot.
To avoid a duplicate ID, run this command to generate a new UUID.
xfs_admin -U generate /dev/sda3 Clearing log and setting UUID writing all SBs new UUID = xxxxx-xxxx-xxxx-xxxxxxxxx |
xfs_admin -U generate /dev/sda3 Clearing log and setting UUID writing all SBs new UUID = xxxxx-xxxx-xxxx-xxxxxxxxx
