(EDIT: The blkid command will also show you the UUID, even if the device is mounted.) You can view the UUID for a volume by attaching it but not mounting it, then running xfs_db to examine the attached disk: # xfs_db -c uuid /dev/nvme1n1 Because the EBS snapshot/restore process is a block-level copy, any volumes you create from a snapshot will have the same UUID as the source volume so you can only mount one at a time. (This example is from a t3 instance using NVMe storage, but it's not NVMe-specific.)Д®very XFS filesystem has a (supposedly) unique ID stored on-disk, which protects you from accidentally mounting the same filesystem multiple times. The error message from mount isn't very helpful, but you may see errors like this in /var/log/messages or equivalent: Jan 13 23:30:29 ip-172-31-15-234 kernel: XFS (nvme1n1): Filesystem has duplicate UUID 56282b3b-c1f3-425e-90db-e9e26def629d - can't mount If the instances were launched using the same AMI then their root volumes will have been created from the same EBS snapshot, so the problem is likely duplicate XFS UUIDs. */dev/xvde1: SGI XFS filesystem data (blksz 4096, inosz 512, v2 dirs)*Д®c2-user]# mkfs -t xfs /dev/xvdf1 //Tried formatting xvdf1 */dev/xvdg1: SGI XFS filesystem data (blksz 4096, inosz 512, v2 dirs)* */dev/xvdf1: SGI XFS filesystem data (blksz 4096, inosz 512, v2 dirs)*
