Error when mounting drive
I created an EC2 amazon instance (ubuntu) and created a volume from an available snapshot. The volume has been successfully attached to my instance as /dev/sdf.
I executed the following command: performed: mkdir /space
When I try to execute the following command: sudo mount /dev/sdf1 /space
I get this message: mount: special device /dev/sdf1 does not exist
How can I solve this issue ?
Try mounting the device "/dev/sdf" instead of "/dev/sdf1".
If that still doesn't work, try mounting it as "/dev/xvdf" or "/dev/xvda1", e.g.:
sudo mount /dev/xvda1 /space
The explanation for this name mismatch can be found in the "Attach Volume" dialog of the EC2 management screen:
Note: Newer linux kernels may rename your devices to /dev/xvdf through /dev/xvdp internally, even when the device name entered here (and shown in the details) is /dev/sdf through /dev/sdp.
In my CloudFormation UserData section I had the attach-volume command and mount command execute sequentially without a delay. I introduced a 5 second delay between the attach-volume command and mount command and it solved the problem.
aws ec2 attach-volume --volume-id $volumeId --instance-id $instanceId --device /dev/xvdf sleep 5 mount /dev/xvdf /db -t ext4
Complementing David Levesque answer.
You can check which volumes have been mounted with. The following will list them all:
$ sudo lsblk --output NAME,TYPE,SIZE,FSTYPE,MOUNTPOINT,LABEL
You will get something like that
NAME TYPE SIZE FSTYPE MOUNTPOINT LABEL xvda disk 8G └─xvda1 part 8G ext4 / cloudimg-rootfs xvdf disk 30G └─xvdf1 part 30G ext4 cloudimg-rootfs
Then you can mount it with
$ sudo mount /dev/xvdf1 /space -t ext4
I hope it helps
