I had a 40 gb drive that was spitting out errors left and right, so I got an 18 tb drive to replace it. I shut down my file system, took out the 4gb drive, and put the 18tb drive in. Once I rebooted the system, it said a 10tb drive was gone, and now a 5tb drive is gone. I did not touch them or change the plugs on them, so I have no idea why they just stoped working. What can I do?

delete lots of attached files that should have been a single zip

Diagnostics is a single zip file. If it appears to you that you have a lot of separate files and folders, it is because your computer automatically unzipped the single diagnostics zip file.

 

I have deleted all those separate files you attached, nobody is going to download them anyway.

 

Please find the single diagnostics zip file on your computer wherever it saves downloads, and attach the single diagnostics zip file to your NEXT post in this thread.

sorry about that here you go

Only a few disks are showing. Parity, disks 1, 3, 4, 5, 6. No disk2, no cache. How many did you have?

 

Looks like one of the controllers is using IDE mode.

 

Go into BIOS and make sure all controllers are using AHCI mode. Then check and make sure BIOS can see all of your disks.

I assume you mean it was a 4TB drive. Is that correct?

 

Was it supposed to be disk2?

ok, so what happened now that I have calmed down a little? I had a 40GB drive that was spitting errors left and right. I shut down the system, took it out, and put an 18 TB drive in to replace it. When I brought the system back up, disk 3 showed this (attached).  I shut down the server again to take a look at maybe a bad connection, but no such luck. After a few simple troubleshooting things of unplugging and re plugging the disk 6 I belive was doing the same thing (no picture sorry). At this point, I think I did a stupid thing and read somewhere that when adding new drives, you have to make a new configuration, and I think that that messed me up even further. Now you should be totally up to speed.

So disk2 really was only 40GB? Why bother with such a small disk?

 

Do you still have all the original disks?

We were using it as a test to make sure the server would do what we wanted at the time.

yes I still have all the original disks

Did it have any data you want to keep?

I don't believe there was anything on it as when you would go into the directories it would show nothing on it but it did says there a little bit in use on it so I dont know if there was anything in it. The bigger ones are the 10tb and 4tb drives not showing up anymore.

 

Normally, Highwater Allocation (the default) wouldn't use that small disk until the others were mostly full.

 

The photo you posted (much better if you can get screenshots to post) shows disk2 wrong. It would normally be OK to replace that disk, except...

Disk3 also wrong. It doesn't look like it really is wrong though. Maybe something to do with IDE mode as I mentioned earlier.

 

Your diagnostics showed

So only disk2 missing, were there supposed to be others?

 

Probably New Config is going to be the way forward here, and might as well do it with the new larger disk2 instead of that 40GB disk. We can try to copy its data if it has any.

Then post new diagnostics

ok It there a way to see the bios though unraid, or do I have to go though the PC?

BIOS is before you boot Unraid.

ok, it will be a while then. I need to get a gppu in the machine and then hook up a monitor

Or if you really want to test rebuild, we can do that too. But the rebuild test would be more meaningful to you if you knew that small disk actually had files on it.

Was the 40GB disk really old? Seems likely since those probably haven't been made for many years. Maybe it just died.

hello, I have some updates for you. I know you said screenshots, but I can't do that on the unraid machine, sorry.

 

Attached it today's diagnostics with a screenshot from my pc.

Drive 3 and 6 are unmountable for some reason even though they were working fine before with data on them

tower-diagnostics-20250326-1505.zip

attached is some bios screen photos

I was hoping to get your disks connected AHCI, not IDE.

 

Are these disk ports on the motherboard, or on a controller card?

these are pluged directly onto the motherborad

According to diagnostics, parity and disk4 are AHCI.

 

Are there any other BIOS screens?

 

Looks like you can scroll down a little on that Standard CMOS Features screen, maybe something there?

 

Been many, many years since I have dealt with IDE master/slave. Any disks with actual IDE connectors are probably in a museum.

 

Maybe if you unplug the DVD you could get all your disks on the master ports.

 

Do you have any documentation for your motherboard?

 

I don't understand why that first photo you posted yesterday said disk3 was wrong since it is displaying the same serial number. I am guessing it got moved to another port, but normally that shouldn't matter since serial number is how Unraid keeps track of disk assignments.

 

Whatever solution we come up with we need Unraid to be able to consistently identify assigned disks.

 

How old is this system you are trying to use for Unraid?

 

 

Here are some lines I compiled from the diagnostics (lspci and lsscsi). I am just leaving this here for future reference and for others ( @JorgeB ) who might have some ideas.

We found how to set up AHCI in the bios and we have turned that on and disabled IDE, have rebooted computer and have re-run diagnostics (attached) and we still have two drives that are unmountable (see screenshot).

Now I'm wondering if that 40GB disk did have an IDE connector.

 

Diagnostics shows only DVD still on IDE so that looks like progress.

 

I'm going to suggest we wait for another opinion from @JorgeB Might be a while, it's probably very late in his timezone.

 

With a normal configuration, I would just say check filesystem and try to repair the unmountable disks. But since the interface has been changing I'm wondering if something else should be tried instead. I think I have seen some threads where rebuilding each from parity due to controller changes was the way to go.

 

Of course, we also already have a disk that needs rebuilt, so that is another thing to consider.

Mar 26 15:04:23 Tower kernel: md3p1: rw=4096, sector=19532873623, nr_sectors = 1 limit=19532871512
Mar 26 15:04:23 Tower kernel: XFS (md3p1): last sector read failed

 

There's an issue with the device capacity not matching, have two questions, do you have the diags when this happened?

 

 

The above suggest the disk was being detected with a different capacity, it would be important to see those diags.

 

The other question, is how was this resolved, next screenshot shows the array started with that disk but unmountable.
