Adding a disk to a virtual server will require that VS should be rebooted. If a VS is running when you try to add a new disk to it, you'll be asked to confirm the reboot. To add a disk to a virtual server:

1. Go to your Control Panel's Virtual Servers menu.
2. Click a VS's label to open its details screen.
3. Click the Storage tab > Disks.
4. Click the "+" button  or the Create Disk button.
5. Fill in the details:
   
   
   • Specify disk label.
   • Choose the data store to create a disk on from the drop-down list.

   • Move the slider to the right to specify the desired disk size.

     The disk size should not exceed 2 TB when a new disk is added. You can later resize the disk if you need it to be larger than 2 TB.

     

   • Move the Hot Attach slider to the right if you want to enable disk hot attaching. In this case virtual server will not be stopped when adding a disk. Hot attach option is only available for KVM 6/ CentOS 6 virtual servers.

   • Move the Swap Space slider to the right if this disk is swap space.

   • Move the Require Format Disk slider to the right if this disk requires formatting.

   • Move the Add to Linux FSTAB slider to the right if the disk should be added to Linux FSTAB (for Linux virtual servers).

   • Specify its mount point. The maximum length of a Mount Point is 256 characters. Spaces are not allowed. No more than one slash is allowed. If the mount point is not specified the default mount point will be used:  

     /mnt/onapp-disk-#{disk.identifier}

   • Tick the Add to FreeBSD FSTAB checkbox if the disk should be added to FreeBSD FSTAB (for FreeBSD virtual servers).
   • Indicate the file system  - ext3 or ext4 - for Linux based VS.

6. Click the Add Disk button to finish.
