    All, I thank you for your responses.  I may set up another smaller (fewer and larger drives) system and copy files over to it, and then upgrade the current system. 

    Keep in mind that your license key file on your USB stick is still valid for current versions, so what you could do is build your new system, get it running with a trial key, migrate your data, then when you are done with the old system you can use the old key and license with the new install. As long as you make good labeled copies of the USB sticks each time you make changes, we can help you accomplish pretty much any end goal configuration you desire.

    Certainly would have been easier with active links.

    I don't think it's fair to expect information from an almost 10 year old thread to still be perfectly valid. Technology has moved a long way since then.

     

    When you get ready to move forward, I recommend you create a new post in the main general support area, briefly outlining where you are and where you want to end up. Include the details of the hardware you are currently using and are willing to purchase for your updated setup.

     

  2. As JorgeB said, migrating just the license key file and super.dat to a fresh install would be best to accomplish an upgrade. Also keep in mind that the file system used in V5, reiserfs, is no longer being updated, doesn't support very large disks, and is going to be removed in the not too distant future. You will need to copy your data to disks with current filesystems.

     

    Perhaps it would be better to set up a new install with fresh disks, then copy the data from the old drives using the Unassigned Devices plugin.

    To me it's overkill and not worth it

    Opinions vary.

     

    If your budget is limiting, a good backup strategy is more important, but if you can afford it, ECC is an insurance policy.

  4. The drives in Unraid are identified by serial number, so as long as the controllers they are attached to doesn't mangle that number, you can move all drives including the licensed USB to another system entirely and the drives will automatically show up.

     

    Unraid also won't arbitrarily add drives without you assigning them to disk slots, so no worries there either.

    Definitely would suggest water cooling,

    As long as the machine will only be running when someone is physically near the machine that will be fine. Liquid cooling is risky unattended. The most common failure mode is pump failure, where the liquid no longer circulates, causing almost immediate overheating with possible CPU damage. If the worst case of a liquid leak happens, you could fry multiple parts.

     

    Air cooling uses relatively massive metal heatsinks, which still dissipate a good amount of heat even when the fan dies, due to convection and air movement from other fans in the system. That gives you plenty of time to find and investigate any failures, where a liquid cooling solution gives very little grace period before things get very warm.

    What do you mean by gaming adapter?

    That's a term that used to be used to describe a wireless ethernet transceiver, when gaming consoles didn't all come with wifi.

     

    It's a device that joins your wifi network and has an ethernet jack that sends the network traffic to the wired device(s) connected to it.

     

    A more current term is a wireless bridge, but you only need one, not a pair.

     

    Here is an example. https://iogear.com/products/gwu637

    currently the Unraid Server will connect by WIFI (yes I know it's not ideal but for now this is what I can do)

    Unraid itself can't use WIFI, but you can certainly set up a gaming adapter to connect to the WIFI and convert it to ethernet so Unraid can use it.

  8. SATA to SATA splitters are not good, to say the least. Practically anything is better, assuming it's compatible with your PSU.

     

    My ideal solution without making custom cables would be to source 4 pin "molex" cables that are compatible with the PSU, then using as few splitters as possible convert them to SATA power.

     

    If the PSU has 3 connectors for hard drive power, then 1 molex from each cable split into 2 SATA using a high quality crimped (not molded) splitter should work well. If you are short on space you could cut off the extra cable after the one molex connector on each cable that you are actually using. Obviously don't do that until you verify that you have the correct cables.

     

    WHATEVER you end up doing, your first priority BEFORE plugging in any drives is to verify the voltage levels are correct at the SATA power connectors. You are playing a high stakes game of russian roulette with very poor odds if you power it up first time with your drives connected.

     

    There are many posts here on this forum, and countless posts elsewhere on the internet about people frying their drives by using cables that physically fit, and were described as compatible. DON'T be another casualty.

    I have 4 RAM sticks, I can try to run the server with only just one.

    Have you done this? Memtest is only definitive when it fails the RAM, passing just means it didn't hit the failure conditions. Last week I had to replace a stick of DDR5 that consistently blue screen rebooted windows 11, yet passed 24 hours of memtest with no issues. I trusted memtest and replaced both the CPU and the motherboard, only to continue to get the same reboots. Replaced the RAM, boom, stable system.

    If scrub detects Permanent errors issue on file you can try to recover files from parity drive.

    There is currently no way to restore a file from Unraid parity. Parity doesn't know which drive contains a bit (or more to the issue, possibly bits on multiple drives) that doesn't match, it only knows that a mismatch has occurred. It may be possible to write code that would iteratively "fail" one drive at a time virtually, and run a scrub through each iteration to see if one of the possibilities is more "correct" than the others, but ultimately there is no way without backup file comparison to be mathematically assured that you made the correct choice. If corruption is found on a ZFS volume (or any file system) in the parity array, the only viable current option is to restore that file from backup.

     

    Parity only deals with 1 specific failure mode, that is, the loss of the entire drive. If parity is NOT in perfect sync across all drives when that occurs, the rebuilt drive will be corrupt. Trying to use parity to deal with file system corruption is not a viable strategy.

    • Power outage put me on ups, which resulted in clean shutdown
    • Power on followed by power outage led to unclean shutdown

    This is exactly why it's recommended to shutdown based on time on battery first. Most of the time if the power is out for more than a minute or so, it's going to be down longer than the UPS can reasonably handle, so it's better to make the shutdown happen ASAP so there is the least battery drain possible. When the power does come back, a second outage is a distinct possibility, so waiting to boot until the battery backup has time to recharge is a good idea, and recharge rates are SLOW. Typical would be 10X, so if the UPS is running for 5 minutes, it's probably going to be close to an hour to recharge back to full.

     

    Also, batteries don't have to be replaced as often if you don't drain them below 50%.

     

    I have all my desktops and VM's set to shutdown after 1 minute of power out, they get their cue with local apcupsd in slave mode looking at the apcupsd master on Unraid. That gets the ball rolling, hopefully all the VM's are down by the time the 3 minute Unraid master shutdown is commanded. All the network infrastructure stays powered until manually shut down or their dedicated UPS is dead.
