Attaching a block volume¶

Attaching a block volume to an instance¶

Attaching volume with existing data¶

First Attach the volume to the instance either during the instance creation, either via UI or the API.

After you have attached the volume, it should become available as a block device such as /dev/vdb.\ \ Next you will need to run these commands on your instance to start using a volume:

Replace <TARGET>with the volume target, e.g. vdb and <DIR_NAME> with the name of the directory you want to mount it to.

Create directory:

mkdir /mnt/<DIR_NAME>

Mount volume:

mount /dev/<TARGET> /mnt/<DIR_NAME>

Recommended: add volume to fstab (this will automatically mount the volume on every system startup):

echo "/dev/<TARGET> /mnt/<DIR_NAME> ext4 defaults,nofail 0 0" >> /etc/fstab

Attaching new block device (with no data on it)¶

If you attach an empty block device, you will first need to format the device. The rest of the steps in the section #attaching-volume-with-existing-data are the same. Format volume (only needed once, e.g, if it's a new volume):

mkfs.ext4 /dev/<TARGET>
