vgcfgrestore -v --file LVMconfig.new vg_devserver
File descriptor 7 (pipe:[18995]) leaked on vgcfgrestore invocation. Parent
PID 3790: bash
  /dev/root: read failed after 0 of 4096 at 27522957312: Input/output error
  /dev/root: read failed after 0 of 4096 at 27523014656: Input/output error
  Restored volume group vg_devserver
