Explanation
A thin-provisioned volume has been taken 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 have performed all of the
actions that you intend to perform, mark the error as "fixed";
the volume copy will then return online.
- Determine why the storage pool free space has been depleted. Any
of the thin-provisioned volume copies, with auto-expand enabled, in
this storage pool might have expanded at an unexpected rate; this
could 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.
- Migrate the thin-provisioned volume copy to a storage pool that
has sufficient unused capacity.
- 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 will automatically
be marked as "fixed", and the volume copy will return 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.
