@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

The task is green, meaning it's done

@m-mirzayev said in ISCSI mount - SR_BACKEND_FAILURE_432: @john-c Would you mind to post your custom.conf so i have a reference? @m-mirzayev I don’t use multipath personally however, though managed to get Microsoft Copilot to put what you gave above into a valid structure. I also remember people in the past having trouble with multipath, so Vates employees implemented this /etc/multipath/conf.d/custom.conf to fix these issues. # /etc/multipath/conf.d/custom.conf defaults { user_friendly_names yes } multipaths { multipath { wwid "your_device_wwid_here" alias "truenas_iscsi" path_selector "round-robin 0" path_grouping_policy multibus path_checker tur prio const failback immediate } } devices { device { vendor "TrueNAS" product "iSCSI" path_selector "round-robin 0" path_grouping_policy multibus hardware_handler "0" prio const failback immediate } } Please replace "your_device_wwid_here" with the WWID of the device on your network.

@Tristis-Oris That's a "known issue": https://xcp-ng.org/forum/topic/7827/xoa-does-not-refresh-quickly-status-of-nics XCP-ng-center is showing the update.
