sync-volumes-to-mdb

This command can be run any time after the initial startup. It synchronizes the EBS volumes currently attached to the system and stores them in the Metadata Database so that on the next restart they will be attached and mounted. The following steps are performed:

• Locates all EBS volumes to the system.

• For all volumes in the managed range, enters an entry to the Metadata Database indicating the following:

  • EBS Volume ID

  • EBS Mount device

  • Operating System mount device

  • Operating system mount point (directory)

• For volumes which are attached but not mounted then the mount point is set to the default mount point for that volume (see the Default EBS Mount Points table below).

No changes to existing attachments, filesystem, or mount points are performed.

The following table lists the default EBS Mount Points. EBS volumes are exposed as NVMe block devices on Nitro-based instances. The device names that you specify in a block device mapping are renamed using NVMe device names (/dev/nvme[0-26]n1). For more information on EBS and NVMe on Linux Instances, see Amazon EBS volumes and NVMe
