Explanation
A space-efficient VDisk has been taken offline because there is insufficient allocated real capacity available on the VDisk for the used space to increase further. If the space-efficient VDisk is auto-expand enabled, then the managed disk group it is in also has no free space.
Action
The service action differs depending on whether the space-efficient VDisk 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 VDisk Copy is auto-expand enabled, perform one or more of the following actions. When you have performed all of the actions that you intend to perform, mark the error as "fixed"; the VDisk Copy will then return online.
- Determine why the managed disk group free space has been depleted. Any of the space-efficient VDisk Copies, with auto-expand enabled, in this managed disk group might have expanded at an unexpected rate; this could indicate an application error. New VDisk Copies might have been created in, or migrated to, the managed disk group.
- Increase the capacity of the managed disk group that is associated with the space-efficient VDisk Copy by adding more MDisks to the group.
- Provide some free capacity in the managed disk group by reducing the used space. VDisk Copies that are no longer required can be deleted, the size of VDisk Copies can be reduced or VDisk Copies can be migrated to a different managed disk group.
- Migrate the space-efficient VDisk Copy to a managed disk group that has sufficient unused capacity.
- Consider reducing the value of the managed disk group warning threshold to give more time to allocate extra space.
If the VDisk Copy is not auto-expand enabled, perform one or more of the following actions. In this case the error will automatically be marked as "fixed", and the VDisk Copy will return online when space is available.
- Determine why the space-efficient VDisk Copy used space has grown at the rate that it has. There might be an application error.
- Increase the real capacity of the VDisk Copy.
- Enable auto-expand for the space-efficient VDisk Copy.
- Consider reducing the value of the space-efficient VDisk Copy warning threshold to give more time to allocate more real space.
