upgrade:

This version includes a fix to the CephFS drivers to address `an issue
|
|
<https://launchpad.net/bugs/1890833>`_ with total and free space calculation
|
|
in the CephFS driver. When you update, you will notice that the space
|
|
calculations reflect reality in your Ceph clusters, and provisioning may
|
|
fail if the share sizes exceed the cluster's free space. CephFS shares are
|
|
always thin provisioned, and the driver does not support oversubscription
|
|
via Manila; so space can be claimed for new shares as long as there is free
|
|
space on the cluster. Use the "reserved_share_percentage" back end
|
|
configuration option to ensure there's always space left aside for
|
|
provisioned workloads to grow over time.

fixes:

The CephFS driver has now been fixed to report total and available space on
|
|
the storage system correctly. See `Launchpad bug#1890833
|
|
<https://launchpad.net/bugs/1890833>`_ for more details.

The CephFS driver now honors the configuration option
|
|
"reserved_share_percentage", and it can be used to prevent save
|
|
space for provisioned workloads to grow over time.
