#Find the SCSI ID for the newly attached volume
sudo ls -l /dev/disk/by-id

/dev/disk/by-id/scsi-3606ca174d8444123a549764ce1085fb5

 

vim /etc/fstab

/dev/disk/by-id/scsi-3606ca174d8444123a549764ce1085fb5 /mnt/disk1 ext4 _netdev,nofail 0 0

Following are descriptions of these field values:

• Device: Specified using the SCSI ID:
• /dev/disk/by-id/scsi-3606ca174d8444123a549764ce1085fb5
• Mount point: The mount point created in the previous step: /mnt/volume1
• Type: The type of file system: ext4 in this example.
• Options:
  • _netdev – Configures the mount process to initiate before the volumes are mounted.
  • nofail – If the device does not exist, no errors are reported. This is a good option to use when an instance is used to create a custom image. Future instances created with that image will not include the block volume and might fail to boot without this option.
• Dump: The value 0 means do not use the obsolete dump utility.
• fsck: The value 0 means do not run fsck.
