Theoretically when you detach and later reattach you should see the VMs. Keep in mind that if you have some disks in storageA while others (same VM) on storageB, import is very hard.<div>Move all disks that belong to the VM on that storage before detaching it.</div><div><br></div><div>If it still happens, check which host is marked as 'SPM' and check on it the vdsmd's logs. Also check the logs in the Engine.</div><div><br></div><div>Best Regards,</div><div>Strahil Nikolov<br> <br> <blockquote style="margin: 0 0 20px 0;"> <div style="font-family:Roboto, sans-serif; color:#6D00F6;">  </div> <div style="padding: 10px 0 0 20px; margin: 10px 0 0 0; border-left: 1px solid #6D00F6;"> <div dir="ltr">Hi,<br></div><div dir="ltr">We're noticing some weird issue while re-attaching the storage domain.
