@pierrebrunet fixed now, thanks.

Question for @pdonias

@olivierlambert You got it, I'll do that. Thank you.

This page is being improved as we speak It shouldn't be in "Future improvements" because it's here

@DustinB I advise you not to decide for others what they should do. I'm tired.

@olivierlambert for what concern backup, I think you should ping @florent for XO-5...

@olivierlambert Just to be sure. Thanks.

No worries, always good to have feedback

@olivierlambert as i say, now it works. So nvm)

@Razor_648 While I was writing my previous message, I have been reminded that there are also issues with LVHDoISCSI SR and CBT, you should disable CBT on your backup job and on all VDI on the SR. It might help with the issue.

@olivierlambert we are thinking about implementing a relationnal DB in the future. Maybe it could offer to stock snapshots as "archived"... I don't know for now. I understand that it could be risky to delete old snapshots, and maybe the responsability of setting the snaspshots retention can be an ACL subject... There are plenty of avenues of work on this topic, and more generally on the retention of information about objects, tasks, and other actions. It's a real in-depth topic.

Thanks for fixing this!

It's still a draft maybe it's not working correctly, @florent might give a look when he can

that a make a sense, now. So no issue here.

Yes, it's a "definition" question/problem: a SR is the exact place where you store your virtual disk images. On NFS, it's a folder named after the UUID of the SR. As Dan said, if you connect to the same NFS folder, it will create a new folder for each new SR inside. So even if it's the same physical device/NFS share, there's many SRs on it. For a block based SR, it's different: if you pass a LUN (in ISCSI for example), it will attach it and warn you: either you want to re-attach the previously existing SR (UUID etc) either you erase it completely to start from scratch. There's no "folders" on a block space like a LUN, so it's different.

@olivierlambert thanks, just to be sure.

@pdonias @julien-f yep fixed now, thanks.

We can make the message clearer, but we advertised multiple time that adding PCI passthrough UI required XAPI changed only available in 8.3
