PowerStore driver doesn't allow more than 32 clones

[Mohammed Naser]

It seems like when using Cinder as an image storage backend, the PowerStore driver will keep creating clones until hitting an internal limit.

REST Response: 422 with data {"messages":[{"code":"0xE0A040010003","severity":"Error","message_l10n":"The clone cannot be created because the max number of clones: 32, in a family has been reached.","arguments":["32"]}]}

This seems a bit like a silly limitation from Powerstore, but it should be something that should be either documented on how to workaround, or the driver should not do copy-on-write copies but instead full copies

Can you provide details on your environment? OpenStack release, PowerStore version and commands that you used when hitting the issue.

After chatting with Product management of PowerStore, this 32 clones is a PowerStore OS limitation and not a bug.
Planned to extend to 64 in next release.
