    [SOLVED] High Disk I/O

    in General Support

    Posted

    Update - closed

     

    system resolved the issue and completed the parity check. Looks like my setup was not the fastest. When I did a speed check on the disks via DiskSpeed plugin, I see that I connected the parity disk to my slowest controller.  My setup has 2 controllers, onboard Super Micro Computer Inc (Intel Corporation) pulling ~200MB/s and a SiI 3114 add in card pulling ~60MB/s. Since I'm still new to unraid, this helps me understand how I need to edit my system a little bit more to tune it up. I have an LSI SAS9211-8i to add in and retest the drive benchmarks with.

    [SOLVED] High Disk I/O

    in General Support

    First off, I can't get into the web ui due to the backlog on my load currently sitting at 53, 53, 53 when I'm running dual L5630 or 16 threads.

    2nd, so I can't post my diagonastics unless I can pull it from my CLI interface and drop it on one of my shares. Please comment if I can pull that from CLI.

    thirdly, I'm on day four of my 3rd preclear of my parity disk. It should have less than 4 hours to go of a 48 hour run, so I'll reboot tomorrow if this backlog doesn't clear.

     

    My CPU usage is low, I have enough ram 64GBs, I've stopped all my dockers and vms from the CLI, but I can't see what is driving my I/O so high. 

     

    Any thoughts?
