For your storage question, it's fully explained in the doc: https://docs.xcp-ng.org/storage/#-how-to-modify-an-existing-sr-connection And yes, it's planned to get the complete error visible in XO, sadly, it's not "obvious" since the error message isn't returned by XAPI when you try to start but by another method we need to call after it fails ("assert can be started here" from the top of my head). Let me ping @julienXOvates

@Danp said: Smart Reboot option found on the host's Advanced tab does what you are asking Very nice!

@florent said: where does this disk comes from From my Redhat 10 @florent said: if you have access to your SR from the outside, you can also put the qcow2 file directly I create a VM to be a NFS to access the 3 HDs, the qcow disks are on the Redhat 10 that I was trying to import from. Do you mean I put the qcow disks on one of the HDs and access them when I create a VM?

@dthenot said: you will also likely need to give the host-uuid of the host the disk is on Thanks, and I'm assuming this UUID or Machine ID from: [14:45 xcp-kbbn NAS]# dmidecode --type SYSTEM # dmidecode 3.0 Getting SMBIOS data from sysfs.

I will give it a try using another folder.... UPDATE 2.1: I executed the command using the above uuid: [15:35 xcp-kbbn srv]# xe sr-create type=udev device-config:location=/srv/NAS name-label="NAS Disks" host-uuid=9a5e5bb3-bdb9-41ea-9505-6f6fe630f369 6fc531a0-19a0-b9c1-c78e-c687fce5ff84 and was successful, but now my question for the device size, is it normal or not due to creating it this way? UPDATE 2.2: I forgot to do: ln -s /dev/sda /srv/NAS/sda #although it might be better to use a stable identifier if you have multiple disks xe sr-scan uuid=<UUID of the udev SR> be right back..... UPDATE 3.0: Success, I have all HDs attached to my VM, access all files and the sizes are reported! : [image: 1779147782991-screenshot-from-2026-05-18-17-25-38.png] List of attached disks: [image: 1779147797114-screenshot-from-2026-05-18-17-18-07.png] The VM: [image: 1779148373193-screenshot-from-2026-05-18-17-51-19.png] Thanks for your help!...

Take it with a grain of salt, but I think bonds are usually managed as a whole rather than edited port by port in the UI. As far as I can tell, the supported route is from the network section in Xen Orchestra (the bonding part of the infrastructure docs is here: https://docs.xen-orchestra.com/xo5/manage_infrastructure#network-bonding), and on the CLI side, the bond commands are documented at https://docs.xcp-ng.org/appendix/cli_reference#bond-create (there's a matching bond-destroy command alongside it). My honest guess is you may end up destroying and recreating the bond with the four ports you want to keep, since I'm not sure removing a single member in place is exposed anywhere, but I could easily be wrong. If there's a cleaner way that avoids the recreate, someone will let us know.

Thanks a lot!

@olivierlambert said in NFS ISO: Cannot read property 'Export' of undefined: Let's consider this thread fixed by adding the correct NFS configuration on the server side and create a new one describing your issue.

@ravenet said in Manually Mount A HD When Needed From XCP-ng?: You can script mount and umount commands as part of jobs or as part of backup jobs.

Correct, I made changes to pfSense to be my DHCP and DNS Resolver, so had to make that change to the NFS Settings to reflect the Domain Name. Thanks for your help!...

Cancel that! I found the keys icon for sending the combo just above console.....

Cancel that, I found out how to save the Config and import through Settings/Remotes/Config...
