Zimaboard2: what do LEDs mean on PCIe riser?

Hardware ZimaBoard
1

Hello!

  1. What do the red and blue LED on the PCIe riser board, which comes with the HDD tray, mean actually? They show a continuous, static light.
  2. Is there anything on the Zimaboard 2, which indicates HDD activity (read/writes), for the disks mounted into the tray and connected to the SATA ports of the Zimaboard2?

Thank you!

  1. This is the power indicator light, signifying normal operation.
  2. If you want to monitor hard drive activity, you can use tools in your operating system to view it.

Thanks for your response!

  1. I guess the red LED refers then to operating as power indicator? And what does the blue LED signalize?
  2. Sometimes it would be nice to just see it on the physical built, but yes that’s just nice-2-have and not that important. I just got this idea, since the integrated btop, which can be started from ZimaOS’ dashboard, seems not to report disk activities if the disks are formatted with btrfs. At least that’s the info I googled. And indeed btop does not give any hints regarding disk activities of the two attached HDDs, which are formatted with btrfs by default by ZimaOS. It may work if drives are formatted with ext4 for example, but by now I just wanted to go ahead with ZimaOS’ default, which I assume is a good choice for a RAID1 setup. Apart from btop, which in this particular btrfs-based scenario is not helpful, which other tool can you recommend?
