I am no expert on this area, but you probably also need to check the integrity of dm-crypt layer and lvm layer. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1694596 Title: LiteOn NVMe issue To man

I opened a Service Request yesterday with Dell regarding my Lite-On CX2 NVMe Series drive. The workstation group escalated the support ticket to their "High Complexity or Ubuntu" group and told me they would get back to me by tomorrow (in 24-48 hours). The last time this happened, there were 329 d
