Work with Disk Partitions

You can use disk partitions to provide space for local volume groups.

You can create, modify, and delete partitions from the Horizon Web interface or the CLI.

To use StarlingX OpenStack, select Admin > Platform > Host Inventory, and then click the host name to open the Host Details page. On the Host Details page, select the Storage tab. For more information, refer to the host provisioning sections in the OpenStack Installation guide.

The following restrictions apply:

• Logical volumes are not supported. All user-created partitions are implemented as physical volumes.

• You cannot specify a start location. Each new partition is created using the first available location on the disk.

• You can modify or delete only the last partition on a disk.

• You can increase the size of a partition, but you cannot decrease the size.

• You cannot delete a partition while it is in use (that is, while its physical volume is assigned to a local volume group).

• User-created partitions are not supported for storage hosts.

• Partition operations on a host are limited to one operation at a time.
