COW - COW Discard

Postby jjcrandall » Mon May 21, 2012 4:13 am

I don't know if this is a bug or not. I create a new Snapshot w/ CDP and i get these options
Create_New.png (31.6 KiB) Viewed 6886 times
Whereas if I attache a previously created disk, I get these options:
Mount_Existing.png (31.5 KiB) Viewed 6883 times
I see the Copy on Write & Copy on Write - Discard on the existing device. Is this something that should be visible or available in this build? I'm interested in the idea.

Also, I've got more detail, but maybe a little overkill for a forum posting, Is there email address you typically want this stuff sent to? We have a use case for the technology that I would like to share and get some ideas on.

These options are for devices that have at least one snapshot.

It's a bug as we implement ROW (Redirect-on-Write) rather then COW (Copy-on-Write). Interface bug and we'll fix it. Thank you!
