WAIT-IO and SYSTEM usage are going crazy

1st Official Post

    I've been running OMV for quite awhile, only really updating when needed. I'm running Docker and several services off of it.

    Recently have been getting spikes in wait-io and system CPU usage. Is this indicative of something ... if someone can help me out, I'd appreciate it.

    Thanks!

    Does the load go down when you stop your containers? Is the system exposed to the internet? See anything in the Diagnostics -> Processes?

    A reboot of the server worked to get back to nominal status; I guess that would count as stopping the containers.

    The system is not exposed to the internet. I do use Emby through a docker container, but I believe those connections are secure through Emby Connect.
    After rebooting, I don't see anything out of the norm under Diagnostics -> Processes.

    I just have no idea what caused the system/wait-io spike


    If this happens again, I'll try to grab the Processes and post here.

    Thanks for the quick response.

    I had a power outage and am now getting crazy Wait-IO issues again. No available updates ... Would and upgrade to 7.4 benefit me? Not sure what to do here.



    It said I couldn't post more than 1000 characters so I've posted my Diagnostics -> Processes as a text file.

    Code
        PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND
    226 root      20   0       0      0      0 D  25.0   0.0   3:20.30 md126_raid5
    232 root      20   0       0      0      0 D  12.5   0.0   0:59.06 md126_resync

    Your RAID is resyncing, so, you'll have to wait till it ends. (hence the large IO wait)


    I don't use RAID but there should be some command lines that will tell you more about it.
