I "Detach Volume" and "Attach Volume" again.

After that I want "Instance Start" but I get immediately message

Error starting instances

Invalid value 'i-{id}' for instanceId. Instance does not have a volume attached at root (/dev/sda1)

Q so where the error occured?


Answer is very easy,

when you "Attach Volume" again set parameter:

Device: /dev/sda1

WARN! If you haven't own "Elastic Network Interface (ENI)" beware change of address on "Instance Start".

Thanks M. Brown

With /dev/sda1 won't work anymore. Directly specify xvda (just it, without /dev) on the Device field.

(well, seems a transient issue, this happened in Oregon region, I tried it in Ireland and you got to specify /dev/sda1 as usual)

  • it’s good to know for $oregon – BG BRUNO Oct 2 '17 at 18:26
  • It doesn't work either. – Alex G.P. Apr 16 '19 at 10:00
