Create a new filesystem file system at /var/lib/docker/ and mount it persistently on the host:

1. Validate that you have a Verify enough free disk to use. Hereexists before proceeding. In the example below, the additional free disk space is under nvme0n1.

   Code Block
   lsblk

   Image Modified

2. Create the filesystem file system using the following command:

   Code Block
   mkfs.xfs /dev/$device

   
   

   Tip
   title Tip
   Replace $device with the name of your actual device in all the following commands. Examples are provided for the reference system.

   for For example: 

   Code Block
   mkfs.xfs /dev/nvme0n1

   

3. Create the mount point for Docker using the following command:

   Code Block
   mkdir -p /var/lib/docker/

   

4. Mount the new filesystem file system at /var/lib/docker/:

   Code Block
   mount /dev/$device /var/lib/docker/

   for For example: 

   Code Block
   mount /dev/nvme0n1 /var/lib/docker/

   Image Modified

5. Update /etc/fstab to ensure the changes persist are still present after a reboot: 

   Code Block
   echo "/dev/$device /var/lib/docker xfs    defaults,noatime  1   1" >> /etc/fstab

   / for

   For example:

   Code Block
   echo "/dev/nvme0n1 /var/lib/docker xfs    defaults,noatime  1   1" >> /etc/fstab

6. Please pause here and

   Before continuing, ensure your system is up-to-date, and

   also to

   validate

   the persistence of

   the storage configuration settings are accurate.

   Assuming

    Assuming that there are no other production applications running on this server, execute the following command: 

   Code Block
   apt-get update -y && reboot (Ubuntu)

   
   

   yum update -y && reboot (CentOS)

7. Validate that the storage configuration persisted settings are accurate after the reboot , using the following command:

   Code Block
   df -h
