Hello, I have few questions about general snapshots functionality. I am actually writing storage driver for HPE 3PAR array and I hit some design incompatibilities.
Snapshots hierarchy - on 3PAR each snapshot of volume is independend, so there are no children or parents. Only parent is base volume and base volume can have children.
So I need folowing two things:
have flat snapshots like on this screenshot (from CEPH issue). How it is possible?
in 3PAR is not “active” snapshot. Base volume is still active with latest changes, snpashots contains data from creating time (resp. just point to some time), so I need to delete any snapshot without restrictions like “have children”, “is active”
You must set ALLOW_ORPHANS=YES in oned.conf for your datastore’s TM_MAD_CONF and in the templates of the datastores using this TM_MAD if they were created after the change.
Hello, thank you! Just another thing, after snapshot, last snapshot is marked “active” can this be disabled by config, or I have to do ‘onevm update-body’ command?
