[pve-devel] checking output of storage plugin API - volume_rollback_is_possible(..., blockers)

[Andrei Perapiolkin]

Hi,

I'm trying to test specific aspects of the storage plugin API,
and I'm not sure how to verify whether my function 
volume_rollback_is_possible
correctly sets up the blockers list.

I've checked REST API documentation:
https://pve.proxmox.com/pve-docs/api-viewer/index.html#/nodes/{node}/qemu/{vmid}/snapshot/{snapname}/rollback

CLI tool:
qm rollback

But I couldn't find where the list of blockers is returned or printed.

Are there any posts, guides, or documentation on how to test blockers or 
other return values from storage plugins?



Best regards,

Andrei Perepiolkin
