Vultr Block Storage

Published on: Fri, Jan 29, 2016 at 1:05 pm EST

Vultr's Cloud Block Storage technology allows you to mount high performance scalable storage to your instance, making space management significantly more flexible. This storage is highly available, redundant, and SSD backed for superior performance.

During the Beta period, Block Storage will be available in our New Jersey location.

How do I mount and format my new storage device?

The first block storage device is connected to your server as /dev/vdb. Additional devices will be relabeled ( /dev/vdc, /dev/vdd, and so forth). By default, we do not create any filesystems on block storage volumes.

(Linux) Create partitions:
# parted -s /dev/vdb mklabel gpt
# parted -s /dev/vdb unit mib mkpart primary 0% 100%

(Linux) Create filesystem:
# mkfs.ext4 /dev/vdb1

(Linux) Mount block storage:
# mkdir /mnt/blockstorage
# echo >> /etc/fstab
# echo /dev/vdb1 /mnt/blockstorage ext4 defaults,noatime,nofail 0 0 >> /etc/fstab 
# mount /mnt/blockstorage

Can I upgrade or downgrade my block storage?

Yes! You can upgrade or downgrade your block storage. However, you will be required to resize your file system manually which does pose the risk of possible data loss if performed incorrectly.

How do I upgrade my block storage?

  1. From under My Servers, click on Block Storage.
  2. Click on the Manage Action button next to the block storage you wish to upgrade
  3. Click on [Modify] and update the new size for your block storage then click the Update button.

** This will require a reboot of your instance from your control panel

(Linux Example) how to properly resize your block storage to reflect the changes made in your panel:

** Prerequisite - you must install gdisk in order to complete the following steps

 # umount /mnt/blockstorage
 # growpart /dev/vdb 1
 # umount /mnt/blockstorage
 # e2fsck -fp /dev/vdb1
 # resize2fs /dev/vdb1
 # mount /mnt/blockstorage

Can I mount block storage to different regions?

No. Block storage may only be attached to instances in the same region.

Can I take/restore a snapshot of a block storage device?

No, this is not currently supported. Additionally, automated backup do not back up block storage volumes.

Can I mount block storage to multiple servers at the same time?

No, this is not possible.

Can I mount multiple block storage volumes to the same VC2 Instance?

Yes, you can.

How many block storage volumes can I attach to a single instance?

While there is no hard limit set, you should not mount more than 8~10 volumes in order to not affect the stability of your instance.

Can I mount a block storage volume on a Vultr dedicated instance?

No, this is not possible.
