Copying an OS to a SSD
#6
Tinkering, I see there's an nvme-cli deb out there, so I installed it.  And duh, it has a man page.  It looks quite well evolved:
Code:
nvme-1.0
usage: nvme <command> [<device>] [<args>]



The following are all implemented sub-commands:
  list            List all NVMe devices and namespaces on machine
  id-ctrl        Send NVMe Identify Controller
  id-ns          Send NVMe Identify Namespace, display structure
  list-ns        Send NVMe Identify List, display structure
  create-ns      Creates a namespace with the provided parameters
  delete-ns      Deletes a namespace from the controller
  attach-ns      Attaches a namespace to requested controller(s)
  detach-ns      Detaches a namespace from requested controller(s)
  list-ctrl      Send NVMe Identify Controller List, display structure
  get-ns-id      Retrieve the namespace ID of opened block device
  get-log        Generic NVMe get log, returns log in raw format
  fw-log          Retrieve FW Log, show it
  smart-log      Retrieve SMART Log, show it
  smart-log-add  Retrieve additional SMART Log, show it
  error-log      Retrieve Error Log, show it
  get-feature    Get feature and show the resulting value
  set-feature    Set a feature and show the resulting value
  format          Format namespace with new block format
  fw-activate    Activate new firmware slot
  fw-download    Download new firmware
  admin-passthru  Submit arbitrary admin command, return results
  io-passthru    Submit an arbitrary IO command, return results
  security-send  Submit a Security Send command, return results
  security-recv  Submit a Security Receive command, return results
  resv-acquire    Submit a Reservation Acquire, return results
  resv-register  Submit a Reservation Register, return results
  resv-release    Submit a Reservation Release, return results
  resv-report    Submit a Reservation Report, return results
  dsm            Submit a Data Set Management command, return results
  flush          Submit a Flush command, return results
  compare        Submit a Compare command, return results
  read            Submit a read command, return results
  write          Submit a write command, return results
  write-zeroes    Submit a write zeroes command, return results
  write-uncor    Submit a write uncorrectable command, return results
  reset          Resets the controller
  subsystem-reset Resets the controller
  show-regs      Shows the controller registers. Requires admin character device
  discover        Discover NVMeoF subsystems
  connect-all    Discover and Connect to NVMeoF subsystems
  connect        Connect to NVMeoF subsystem
  disconnect      Disconnect from NVMeoF subsystem
  version        Shows the program version
  help            Display this help

See 'nvme help <command>' for more information on a specific command

The following are all installed plugin extensions:
  intel          Intel vendor specific extensions
  lnvm            LightNVM specific extensions
  memblaze        Memblaze vendor specific extensions

See 'nvme <plugin> help' for more information on a plugin

nvme list shows me:
Code:
nvme list
Node            SN                  Model                                    Namespace Usage                      Format          FW Rev 
---------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- --------
/dev/nvme0n1    BTNH93841ZZZ1P0B    INTEL SSDPEKNW010T8                      1          1.02  TB /  1.02  TB    512  B +  0 B  002Cnvme-1.0


From what I'd read I was thinking I'd have to download and build something.  It even has SMART.  Don't know if there's any support for USB-connected nvme.  There's also nothing in there for booting from an nvme device so I'll probably still have to build something.

Oh, OK, in /dev I see:
Code:
nvme0
nvme0n1
nvme0n1p1
nvme0n1p2
nvme0n1p5
Those correspond to my partitions, so /boot is on /dev/nvme0n1p1 and the root (/) is on /dev/nvme0n1p5.  But I knew that before installing nvme-cli, and they're already in /boot/extlinux/extlinux.conf and /etc/fstab.  I just did a locate nvme and it was some sort of revelation.

My SMART log:
