I have any ebs volume mounted to an ec2 instance. Am taking an image so that whenever i need to create a new instance i use the image.I can make the ebs volume re mount if the ec2 reboots. But if i have to use the same image across allec2 machines its not possible because, when we do lsblk the default mounts may not be the same

lsblk of one ec2 machine:

lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0   8G  0 disk 
└─xvda1 202:1    0   8G  0 part /
xvdf    202:80   0  30G  0 disk /data

lsblk of another machine:

lsblk
NAME    MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
xvda    202:0    0   8G  0 disk 
└─xvda1 202:1    0   8G  0 part /
xvdb    202:80   0  30G  0 disk /data

now inspite of xvdb or xvdf i have to mount my ebs volume.

Any Idea?

Label the master volume with a unique label using e2label.

Then, in /etc/fstab, instead of specifying the device by its block device name, specify LABEL=your_label.
