![]() ![]() For example you can assign this device name to a shell variable DEVICE and format and find UUID for the device to be used later in a way : sudo mkfs -t xfs -q $DEVICE So in this case you are straight-forward aware that device /dev/sdf corresponds to some EBS volume with id : vol-01324f611e2463981 - use this information in you provision scripts. With Amazon Linux AMI 2017.09.01 or later (including Amazon Linux 2), you can run the ebsnvme-id command as follows to map the NVMe device name to a volume ID and device name: $ sudo /sbin/ebsnvme-id /dev/nvme1n1 To avoid unpleasant surprises, we recommend identifying devices corresponding to the EBS volumes by the EBS volume ID: vol-01234567890abcdefand not by absolute number.ĭifferent AMIs (and different operation systems distros) allow you to do that in different ways, the most frequently used ones are listed below : Amazon Linux AMIs We are going to look at the situation from the perspective of the Terraform and Linux systems, see section towards the end of this document. In the worst-case scenario - this can lead to the production outage, or broken backup restore (when the absolute device had been specified to LVM operation commands). And that’s how, for example, assigned data-volume for the TFE got suddenly lost during the restart - because often scripts of provision instance specifying either mounts or some other operations based on the absolute device name. The block device driver *can assign NVMe device names in a different order than you specified for the volumes in the block device mapping*. The device names that you specify in a block device mapping are renamed using NVMe device names (/dev/nvmen1). The device names are /dev/nvme0n1, /dev/nvme1n1, and so on. Not Monday yet?
