Resize ARTESCA+ VM Volumes

This procedure describes how to resize the volumes of a ARTESCA+ VM.

Check the Available Space in the Volume Group (VG)

1. Get the free space available of vgartesca Volume Group (VG)

   [artesca-os@bootstrap ~]$
   

   sudo vgs /dev/vgartesca --unit g -o free
   

   VFree
   600.00g
   

Resize the Volume

1. Find the LVM logical volume name you want to resize.

   [artesca-os@bootstrap ~]$
   

   sudo lvs --unit g /dev/vgartesca/vm-*-disk
   

2. Set the LV_NAME variable.

   Note

   Replace <LV_NAME> by the name of the actual Logical Volume (LV) identified in the previous command output.

   [artesca-os@bootstrap ~]$
   

   export LV_NAME="<LV_NAME>"
   

3. Set the LV_EXPANSION_SIZE variable.

   [artesca-os@bootstrap ~]$
   

   export LV_EXPANSION_SIZE="10G"
   

4. Resize the Logical Volume (LV).

   [artesca-os@bootstrap ~]$
   

   vol_fstype=$(lsblk -o FSTYPE -n /dev/vgartesca/$LV_NAME); \
   if [ "$vol_fstype" == "ext4" ]; then \
     sudo lvextend --size +$LV_EXPANSION_SIZE --resizefs /dev/vgartesca/$LV_NAME; \
     vol_mnt=$(lsblk -o MOUNTPOINT -n /dev/vgartesca/$LV_NAME); \
     sudo salt-call --local cmd.run "truncate -s +${LV_EXPANSION_SIZE} ${vol_mnt}/disk.img"; \
   else \
     sudo lvextend --size +$LV_EXPANSION_SIZE /dev/vgartesca/$LV_NAME; \
   fi
   

5. Get the VM name.

   [artesca-os@bootstrap ~]$
   

   sudo kubectl --kubeconfig=/etc/kubernetes/admin.conf get vm -n veeam
   

   NAME             AGE   STATUS     READY
   vbr-1234         63d   Running    True
   

6. Restart the VM to apply the changes (replace <VM_NAME> by the actual VM name returned by the previous command).

   [artesca-os@bootstrap ~]$
   

   sudo virtctl --kubeconfig=/etc/kubernetes/admin.conf restart -n veeam <VM_NAME>
   

Important

Now the VM disk is resized. You can proceed with resizing the corresponding filesystem inside the VM.
