    Nothing obvious, but you might consider a little more RAM, 4GB is not much for v6 and a couple of dockers.

    SSD RAID1

    JorgeB replied to craigr's topic in General Support

    Split your question here since the FAQ thread is reserved for that. You should avoid RAID controllers with Unraid, it might not even work with Linux if it's a "fake" RAID controller, also note that the new beta supports multiple pools, I encourage to use that instead, though I'll leave that FAQ entry up until v6.9 goes stable.

    You can usually get an LSI HBA on ebay for 30€ or so, look for used server pulls.

    Did you try what in the first link, if not do it. Some NVMe devices have issues with power states on Linux, try this, on the main GUI page click on flash, scroll down to "Syslinux Configuration", make sure it's set to "menu view" (on the top right) and add this to your default boot option, after "append" and before "initrd=/bzroot" nvme_core.default_ps_max_latency_us=0 Reboot and see if it makes a difference.

    There are "power on resets" in multiple disks, this is usually a connection/power problem.

    Quickest way would be to do a new config, remove the small disk, assign the new parity and sync it. If the current cache is btrfs you can do an online replacement.
  7. JorgeB
    Check the box "parity is already valid" before starting array, but still a good idea to run a parity check after.
  8. JorgeB
    If you're sure about the parity drive (and are using single parity) data drive order doesn't matter.
  9. JorgeB
    Yep.
  10. JorgeB
    Backup the config folder from the flash drive, redo it using the USB tool, restore config folder.
  11. JorgeB
    Disk looks fine, most likely a connection issue, you can replace/swap cables and try again.
  12. JorgeB
    Yes. If the controller has more than 4 ports it has a built in port multiplier, it can also be connected to an external multiplier, no way to know by the diags. For good reliability we recommend LSI HBAs in IT mode, like the 9211-8i and similar.
  13. JorgeB
    It's not, although the 9240 is a megaraid model, it's a "lite" one, it uses the standard HBA chipset and can be flashed to IT mode, the 9260 can't.
  14. JorgeB
    Cache device drooped offline, it's connected to a Marvell controller and a SATA port multiplier, both are not recommended, especially together.

    Check that Power Supply Idle Control is set to the correct value in the BIOS as mentioned here.

    This can sometimes help: Some NVMe devices have issues with power states on Linux, try this, on the main GUI page click on flash, scroll down to "Syslinux Configuration", make sure it's set to "menu view" (on the top right) and add this to your default boot option, after "append" and before "initrd=/bzroot" nvme_core.default_ps_max_latency_us=0 Reboot and see if it makes a difference.
  17. JorgeB
    First thing to do is to replace the SATA cable
  18. JorgeB
    No.
  19. JorgeB
    There's no SMART report for disk1, check connections and post new diags.

    Best bet is to re-format, there are some recovery options here if you can't just copy the data. Btrfs is very susceptible to bad RAM, but any issue is also usually pretty evident, you can run a file system check (without repair enable) to make sure all is well.
  21. JorgeB
    Here's an example of the slower SMR performance in some drives, due to a config change in one of my backup servers I need to re-transfer all the data, when doing this I disable parity so I can transfer 2 or 3 disks at the same time, using 10GbE (due to the SSH encryption this CPU can only handle about 300MB/s), all 3 disks started transferring within minutes of each other and the 2 SMR drives are going noticeable slower, and the difference will probably be larger for the remaining two disks since there won't be such a CPU bottleneck.

    Click in "Download" link, top right of the forum.

    Start by redoing the flash drive, backup the config folder, recreate the flash using the USB tool, restore the config folder.
  24. JorgeB
    Look for used server pulls on ebay, those are much cheaper, avoid cheap new ones from China, could be fakes. Yep. Cache best to use onboard ports for trim, assuming SSDs, parity won't matter.
  25. JorgeB
    One LSI with 16 ports is enough (plus the other 8 onboard ports), e.g., 9201-16i or 9300-16i, other option and probably cheaper would be two 9211-8i/9300-8i or similar.
