Installation requirements

  • Linux kernel 5.4 or newer, for io_uring support. 5.8 or later is highly recommended because io_uring is a relatively new technology and there is at least one bug which reproduces with io_uring and HP SmartArray controllers in 5.4
  • liburing 0.4 or newer
  • lp_solve
  • etcd 3.4.15 or newer. Earlier versions won't work because of various bugs, for example #12402.
  • node.js 10 or newer
