1865 Thin-provisioned volume copy offline because of insufficient space.


  Explanation
A thin-provisioned volume is offline because there is insufficient allocated real capacity
    available on the volume for the used space to increase further. If the thin-provisioned volume
    is auto-expand enabled, then the storage pool it is in also has no free space.


  User response
The service action differs depending on whether the thin-provisioned volume
    copy is auto-expand enabled or not. Whether the disk is auto-expand enabled or not is indicated
    in the error event data.
If the volume copy is auto-expand enabled, perform one or more of the following actions. When you
    complete all of the actions that you intend to perform, mark the error as fixed; the
    volume copy then returns online.

    Determine why the storage pool free space is depleted. Any of the thin-provisioned volume
     copies, with auto-expand enabled, in this storage pool might have expanded at an unexpected
     rate. It might indicate an application error. New volume copies might have been created in, or
     migrated to, the storage pool.

    Increase the capacity of the storage pool that is associated with the thin-provisioned
     volume copy by adding more MDisks to the storage pool.

    
    Provide some free capacity in the storage pool by reducing the used space. Volume copies
     that are no longer required can be deleted, the size of volume copies can be reduced, or volume
     copies can be migrated to a different storage pool. 
     Note: Migration is not supported for thin-provisioned or compressed volume copies in
      data reduction storage pools.


    Consider reducing the value of the storage pool warning threshold to give more time to
     allocate extra space.

   
If the volume copy is not auto-expand enabled, perform one or more of the following actions. In
    this case, the error is automatically marked as fixed, and the volume copy returns online
    when space is available.

    Determine why the thin-provisioned volume copy used space has grown at the rate that it has.
     There might be an application error.

    Increase the real capacity of the volume copy.

    Enable auto-expand for the thin-provisioned volume copy.

    Consider reducing the value of the thin-provisioned volume copy warning threshold to give
     more time to allocate more real space.

   
   Remember: If the volume is thin-provisioned or compressed, the
     -autoexpand parameter must be enabled or the mkvdisk
    command fails.
