Personally, I use 4 TB IronWolf Seagate drives.
both for parity as for data.
Cache drive is recommended too. (i use 500gb Intel 660p m2)I only can have a max of 4 drives rn and Cant upgrade much

Hello, I have one 1tb WD drive as paraity and another for data plus two segate 500G drives.
Any suggestions as I have no money to upgrade?
Some are old with 4-5 hour runtime and 2 are around 1 year.
Thankyou

As safe as your last full backup. Given all you've said here, you would be better off copying anything important to you onto your spare drives and keep them away from the server. Parity depends on the health of all the drives, not just the parity drive, so you would be better covered as far as data loss is concerned by concentrating on keeping 2 up to date copies, one on the server for immediate access, and 1 on your spare drives for when the drives in your server quit.
Parity doesn't protect against data corruption or deletion, doesn't matter if it's user error or hardware.
Since you don't have money for more drives, using a drive for parity is a waste when you could be using it as an actual backup. As it stands right now with your screenshot, you can easily back up the entire content of your server (645GB) on to the 1TB drive you propose to use as parity.
Hmmmm. Good Idea. Is there a plugin that could do that for me or is there an easy way to automate this?
Is there maybe a different server OS that would work better for me.
Thankyou again!

Tools, New Config.
Adding a SATA HBA would be a viable option, but if you aren't going to need to add much capacity, it would be cheaper and faster to just use larger drives. My suggestion would be to add an 8TB as parity, then when you run out of space upgrade one of the remaining 500GB with another 8TB, and you would be set for a while.
BTW, parity is NOT backup, it's high availability. It allows you to continue to use your server uninterrupted if a drive fails and you replace it. Parity can NOT repair corrupt or deleted files, or fix a corrupted filesystem. It only rebuilds a failed drive with exactly the content that was on it when it failed, if the content was corrupted, the rebuild will be corrupted as well. Parity also relies on ALL the remaining data drives to be read perfectly from end to end, so you must be sure all your data drives are in perfect health. Since some of your drives are over 10 years old, that may be questionable.
What If I add a 1tb drive in spot of the 500G WD - I dont really have the bugget to upgrade or get new disks.
If I did that how safe would my data be? I have my server on a UPS and it is setup to avoid a power outage that may cause corruption.
Thankyou for your help!

Hello, I currently have 4 sata ports in my old system. All in use, I need to remove one of the data drives and replace it for a parity for backup. I believe the highlighted disk is blank because it shows no files on it. I want to change that out to a 1TB disk for parity. How do I procede with this?
TIA! (There is two images)
Edit - What if I just get a SATA card for more ports?

Hi there,
Have you gone into the BIOS itself and toggle the boot order? Immediately after pressing power, you should be able to spam the F10 or Del key and enter the BIOS. From there you need to find where you can toggle your boot devices. In addition, you may want to try re-imaging your flash drive, clicking the Customize button, and selecting UEFI Boot. Give that a try.
Yes. There is two items listed - the UEFI usb drive for just the usb drive. I have tried both. I have sleected in boot mode. How do I reimage without loosing my data
-
Just now, trurl said:
UEFI if it works, legacy if UEFI doesn't work. You would also have to make sure your BIOS is using whichever your flash is using.
I tried both. Not working, I got it to work on another MOBO. Transferring data and then giving freenas a shot. Thanks for the help

Just now, trurl said:
UEFI or legacy boot?
I have tried both I think. which one should I use?

Do you mean the Unraid flash drive you have prepared will boot in another computer?
Yes It works fine in other PC. I can boot to usb windows installer on server but not unraid

Try to get another computer to boot from the Unraid flash. If that works you know that you need to work on getting your server to boot from that same flash.
And / Or
Try to get something other than Unraid to boot from a flash drive on your Unraid server.
This will help you decide what you need to work on, getting the server configured so it will boot to a flash drive, or getting the Unraid flash drive prepared so it will boot from the server.
Be sure to boot from a USB2 port.
I tried another computer and it works. I am booting from that flash drive and it does the same thing. I can boot to a windows install USB disk and it is in a usb2 port. What else can I try. This is a very odd issue

Is the boot order correct?
I think so

I select my boot device using f11. Is that what you mean? Sorry, I am not that experienced.

Hello unraid community. I can not get my unraid machine to boot. I only get a flashing white line in the top left. (See Picture)
I can boot other OS's and everything in the computer seems to be working fine. Any help is very much welcome. Thankyou!

Just to clear up some terminology for you. The parity drive(s) plus the assigned data disks ARE the array. In other words, parity is in the array by definition. If you notice in your screenshot the heading above parity and those assigned data disks it says "Array Devices".
Flash, cache disks and any unassigned disks are not in the array.
Yes, I know. Sorry, my bad - bad wording

Yes. The number of simultaneous array drive failures that can be handled is the same as the number of parity drives.
If you DO happen to get a drive failure and are not sure how to proceed then ask here in the forum first. Taking the write action will recover your data, but taking the wrong action can result in data loss.
It is worth pointing out that you should still have a backup strategy in place for any data you really cannot afford to lose. Although unlikely it is possible that some catastrophic event (e.g. PSU going rogue, lightning strike) could fail multiple drives simultaneously and the simple recovery process will not work. Unraid is good at handling even such events if one is careful but you do not want to rely on this being the case.
Ok. Thanks so much!

Is that 1TB drive going to become a new parity1 drive? If so that would be OK. If not then your array would be unprotected against drive failure. It is perfectly OK to run unprotected if you have a backup strategy in place to recover data if a drive fails, but most people prefer to have at least one level of parity protection in place.
I am going to have one 1tb drive for parity. Just to make sure if one drive fails on the array all data on that drive will be rebuilt, correct?

It is worth pointing out that the 2nd parity disk works in a similar way to that described for parity1 in the suggested link but uses a different mathematical formula so that parity2 is independent of parity1.
Ok. Thanks, everyone for your input. I really appreciate it. I am going to remove all parity drives and install a 1tb drive. I will move the parity drives to the main array. Thanks, everyone for your input! Let me know if I made a stupid mistake in what I just said I am going to do

All your data IS protected! When a drive fails it is reconstructed using the combination of the parity drive plus ALL the other data drives.
you might want to read the Wiki to understand how parity works.
Ok. This is all very confusing to me.
I just want to make sure that all data is safe and happy with the new parity.
As long as it is I am going to continue with this new config.
One more question. How does another parity drive help protect data more?
Sorry for all the questions. I am not very familiar with this mode of backup/data protection.

Personally I wouldn't bother with dual parity with so few disks.
If I have a 1tb drive as parity and 1320gb as my main data not all of my data will be protected, correct?
-
OK. Thanks
-
Here is my current unraid setup. I want to add a 1tb drive to my array. I was going to move one of my 500g parity drive to my main array and then add the 1tb drive to the parity slot I just switched out. Is this how I should do this or should I only have one parity drive?
I WANT TO HAVE ALL MY DATA PROTECTED IN CASE OF A DRIVE FAIL.
IF I SETUP MY ARRAY WILL ALL DATA BE PROTECTED?

What is the default login for mineOS

When I got on today it was working. I am not sure what I did.
Thanks, everyone for your help.

Check if Windows is requiring SMB signing, use Windows Powershell and type:
Get-SmbClientConfiguration | fl EnableSecuritySignature,RequireSecuritySignature
Default and correct is:
EnableSecuritySignature : True RequireSecuritySignature : False
If RequireSecuritySignature is true that's your problem.
My response is
Get-SmbClientConfiguration : A positional parameter cannot be found that accepts argument ''.
