Updating a disk

Written by

After you create a disk, you can:

Changing the name and description of a disk

To change the name and description of a disk:

  1. In the management console, select the folder where you will be editing a disk.
  2. In the list of services, select Yandex Compute Cloud.
  3. On the left-hand panel, select Disks.
  4. Click next to the desired disk and select Edit.
  5. Change the name and description of the disk.
  6. Click Save changes.

Compute Cloud will start the operation to update the disk.

If you don't have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

  1. View the description of the CLI's disk change command:

    yc compute disk update --help

  2. Request a list of available disks:

    yc compute disk list

    Result:

    +----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+
|          ID          |     NAME     |    SIZE     |     ZONE      | STATUS |     INSTANCE IDS     |       DESCRIPTION       |
+----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+
| a7lqgbt0bb9s40tifuhc | first-disk   | 20401094656 | ru-central1-a | READY  | a7lcvu28njbhnkcteb5n |                         |
| a7lv5j5hm1p1hppprga7 | second-disk  | 21474836480 | ru-central1-a | READY  |                      |                         |
+----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+

  3. Select the ID or NAME of the required disk (for example, first-disk).

  4. Specify the name and description in the disk change command:

    yc compute disk update first-disk \
  --new-name updated-disk \
  --description "Updated disk via CLI"

    Compute Cloud will start the operation to update the disk.

You can change a disk name and description with the API update method for the Disk resource.

Use the list method for the Disk resource to retrieve a list of available disks.

Increasing a disk's size

Note

You can only change the size of a disk by increasing it. You cannot reduce the size of a disk.

You can only increase the size of a disk that is not attached to a running VM. To increase the disk size, make sure that the VM is stopped.

  1. In the management console, select the folder where the disk is located.
  2. In the list of services, select Yandex Compute Cloud.
  3. On the Virtual machines page, stop the virtual machine (see Stop).
  4. Wait until the VM status changes to STOPPED.
  5. On the left-hand panel, select Disks.
  6. Click next to the desired disk and select Edit.
  7. Increase the disk size.
  8. Click Save changes.
    Compute Cloud will start the operation to change the disk size.
  9. When the operation finishes, go back to the Virtual machines page and restart the VM.

If you don't have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

  1. View the description of the CLI's disk change command:

    yc compute disk update --help

  2. Request a list of available disks:

    yc compute disk list

    Result:

    +----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+
|          ID          |     NAME     |    SIZE     |     ZONE      | STATUS |     INSTANCE IDS     |       DESCRIPTION       |
+----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+
| a7lqgbt0bb9s40tifuhc | first-disk   | 20401094656 | ru-central1-a | READY  | a7lcvu28njbhnkcteb5n |                         |
| a7lv5j5hm1p1hppprga7 | second-disk  | 21474836480 | ru-central1-a | READY  |                      |                         |
+----------------------+--------------+-------------+---------------+--------+----------------------+-------------------------+

  3. Stop the VM with the disk you want to update. To do this, select the ID of the VM:

    yc compute instance stop --id a7lcvu28njbhnkcteb5n

  4. Select the ID or NAME of the required disk (for example, first-disk).

  5. Specify the size (for example, 32 GB) in the disk change command:

    yc compute disk update first-disk \
  --size 32

    Compute Cloud will launch the operation to change the disk size.

  6. Run the VM:

    yc compute instance start --id a7lcvu28njbhnkcteb5n

You can increase the disk size by using the API update method for the Disk resource.

Use the list method for the Disk resource to retrieve a list of available disks.

To stop or start a VM, use the stop and start methods for the Instance resource.

Increasing a partition

After increasing the disk size, you also need to increase its partition and file system. For boot disks, this should be done automatically.

If the disk partition doesn't increase or you're increasing the size of a non-boot disk, do this manually:

  1. Connect to the VM via SSH:

    ssh <username>@<VM public IP>

  2. See the disks attached to the VM:

    lsblk

    Command output:

    NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda    252:0    0  25G  0 disk
├─vda1 252:1    0   1M  0 part
└─vda2 252:2    0  25G  0 part /
vdb    252:16   0  64G  0 disk
└─vdb1 252:17   0  32G  0 part

    Disk partitions are listed in the NAME column.

  3. Check and restore the file system:

    sudo e2fsck -f /dev/vdb1

    Command output:

    e2fsck 1.44.1 (24-Mar-2018)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/vdb1: 11/2097152 files (0.0% non-contiguous), 143890/8388352 blocks

  4. Change the partition size:

    sudo growpart /dev/vdb 1

    Where:

    • /dev/vdb is the name of the device.
    • 1 is the partition number, so it's separated by a space.

    Command output:

    CHANGED: partition=1 start=2048 old: size=67106816 end=67108864 new: size=134215647,end=134217695

  5. Change the file system size:

    sudo resize2fs /dev/vdb1

    Where:

    • dev/vdb1 is the name of the partition.

    Command output:

    Resizing the filesystem on /dev/vdb1 to 16776955 (4k) blocks.
The filesystem on /dev/vdb1 is now 16776955 (4k) blocks long.

  6. Make sure that the partition increased:

    lsblk

    Command output:

    NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda    252:0    0  25G  0 disk
├─vda1 252:1    0   1M  0 part
└─vda2 252:2    0  25G  0 part /
vdb    252:16   0  64G  0 disk
└─vdb1 252:17   0  64G  0 part

  1. Connect to the Windows VM using RDP.

  2. In the search bar, type diskmgmt.msc to perform a search by system and start the found snap-in.

  3. In the Disk Management window that opens, select the desired disk. Open the context menu and select Extend volume...

  4. Enter a new partition volume and confirm the action.

  5. Make sure that the partition increased.
