How to increase your Block Storage volume size

With Block Storage it is possible to expand the volume size of an Instance.

How to increase the volume size from the Scaleway console

1. Click the Volumes tab on the Instance information page of the console. A list of your volumes displays.

2. Click «See more Icon» beside the volume you want to increase and then click Increase Volume.

3. Increase the size according to your preference with the «Plus Icon» button.

   

   

4. Click Increase your Volume to confirm.

   Note:

   Currently, only the increase of a Block Storage volume is supported. The maximum size of a Block volume is 10 TB.

How to increase the partition size of the volume

1. Connect to your Instance using SSH.

2. Use the lsblk command to identify your Block Storage volume’s mount point. In the following example the volume is mounted at /mnt/block-volume:

   root@scw-friendly-beaver:~# lsblk
   NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
   loop0     7:0    0 61.9M  1 loop /snap/core20/1270
   loop1     7:1    0 67.2M  1 loop /snap/lxd/21835
   loop2     7:2    0 43.3M  1 loop /snap/snapd/14295
   sda       8:0    0  9.3G  0 disk
   ├─sda1    8:1    0  9.2G  0 part /
   ├─sda14   8:14   0    4M  0 part
   └─sda15   8:15   0  106M  0 part /boot/efi
   sdb       8:16   0 37.3G  0 disk
   └─sdb1    8:17   0 23.3G  0 part /mnt/block-volume
   Copy code

3. Unmount the volume:

   umount /mnt/block-volume
   Copy code

4. Check that the volume is unmounted by running the lsblk command.

5. Use growpart to increase the partition size of your block storage volume (here /dev/sdb1):

   growpart /dev/sdX 1
   Copy code

   Tip:

   Take a note of the space between the device identifier and the partition number.

6. Increase the partition size of the volume using resize2fs. Replace /dev/sdX with the name of your block volume in the following command:

   resize2fs -p /dev/sdX1
   Copy code

7. Run e2fsck on the Block Storage volume to check that everything went well. Replace /dev/sdX with the name of your block volume in the following command:

   e2fsck /dev/sdX1
   Copy code

   An output like the following example displays. The status of your file system should be clean

   root@scw-elegant-franklin:~# e2fsck /dev/sda
   e2fsck 1.45.5 (07-Jan-2020)
   /dev/sda: clean, 11/1827840 files, 158770/7324218 blocks
   Copy code

8. Remount the volume to access the files stored on it:

   mount -o defaults /dev/sda /mnt/block-volume
   Copy code
