EC2 - EBS Mount (NVME)

 

 

 

1. 마운트 시키기 

 

lsblk

 

sudo mkfs.ext4 -E nodiscard /dev/nvme1n1

sudo mkdir -p /mnt/vol1

sudo mount -o discard /dev/nvme1n1 /mnt/vol1

 

2. UUID 구하기

 

sudo lsblk -o +UUID

root@ip-172-31-37-156:/mnt/vol1#lsblk -o +UUID
NAME        MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT                  UUID

3. 자동 마운트 등록

 

sudo vim /etc/fstab

 

UUID=95c89dcb-ea7e-42f2-ba84-349389a19243  /mnt/vol1  ext4  defaults,nofail  0  2

Mount Separately
----------------
# mount nvme SSDs to /dataN when available for specific instance types
# There are only 4 nvme slots in r5 instances. /dev/nvme0n1 is root EBS volume.
for i in $(seq 1 4); do
  if [ -e "/dev/nvme${i}n1" ]
  then
    echo "Mounting /dev/nvme${i}n1 to /data${i}"
    sudo mkfs.ext4 -E nodiscard /dev/nvme${i}n1
    sudo mkdir -p /data${i}
    sudo mount -o discard /dev/nvme${i}n1 "/data${i}"
    lsblk
  fi
done

Mount as LVM
------------
for i in $(seq 1 4); do
  if [ -e /dev/nvme${i}n1 ]
  then
    x+=" /dev/nvme${i}n1"
  fi
done

yes | sudo pvcreate $x

yes | sudo mkfs.ext4 /dev/nvmevg/nvmelv
sudo mkdir -p /data
sudo mount /dev/nvmevg/nvmelv /data
