My unraid keeps on saying "Please wait... collecting diagnostic information (this may take several minutes)" ... It has been over 15 minutes now. Does it take so long ?

Nope...I am running version 6.6.6

I did enabled the logging and set cache yes...It says mover is running but i dont see any file in my main data disk/.

I am on Unraid 6.6.6 and I ahve 2.5 TB on my cache drive. I clicked on "Move now" button under "Main" and it is still not moving data into my main data drive. Do i need to do anything else as well ?

I did Main-->Move now but i dont see files getting created in my main data drive.

I recently created new array and performed preclear. after adding the disks I am getting orange triangle on data drive and not sure what's wrong there ? Can someone please help and explain ?

Thanks Johnie. You are awesome.

So far i have done preclear only 2 times on Parity and 1 time on Data Disk (Disk 3). Before I add them to array do you suggest to do preclear again 22-3 times ?

Hi Johnie and Turyl, Here are the Stats when i ran preclear on new 8 TB Disk. Still Slow as compare to 1 st preclear result but much better than previous 8 TB Hard Disk. Should I run preclear again on both Disk 1 and Disk 3 together again 2nd time ?

Thank you. Will do so and share the results. Once again THANK YOU VERY MUCH.

I am confused with that statement. What do you mean ?

Thanks. So are you suggesting to cancel currently running preclear and do the same again but this time only on the disk which is running slow as per preclear ?

Hi Johnie, What do you mean by if preclear stats are correct ? Is there any possibility of same as well ? I attached preclear results so i believe i am reading it right. Please help.

Hi Johnie and Turyl, As you suggested I have done some test and I was wondering if you can share your inputs on same. Below is a brief summary of what i have done so far. Purchased two 8 TB Seagate Hard Drives from Costco At Same time. Both are connected to Proliant N54L with 8 GB RAM exactly in same way via SATA Connector (both connected to Motherboard via same SAS connector) There are no other Hard Disks connected to Proliant machine as of now except these 2. Unraid ver 6.6.6 was installed alongwith Community applications and PreClear Disk (from gfjardim's plugin Repository) I started preclear on both hard disk almost at same instant. Disk 1 Took in total under 47 hrs to finish preclear. Out of these 47 Hrs it took rought 15 hrs for Step 2 i.e. "Zeroing the Disk" at average speed of 144MB/sec. Screenshot attached below. Disk 2 has already taken 66+ hrs and still preclear is not finished. Out of 66+ hrs it has consumed 51 hrs in Step 2 and still only 58% completed. Step 2 is running at average speed of 25MB/sec.Screenshot attached below. I am feeling as if I have just got one of the bad hard disk (Disk 2) which is causing this issue but other hard disk (Disk 1 ) is correct. Can you guys please share your views on same ?

Interesting...I Started Preclear on both 8 TB Disks that i got from Costco at same time...Currently both are running (in N54L with 8 GB RAM) but i can see huge difference in speed. Preclear is not yet completed but see the current status....

So Are we concluding that its definitely Hard Disk fault ??

Somehow i feel there has to some other reason. I started preclear as someone suggested in Seagate * TB thread and just wanted to check the speed. Currently it is 3% done but it is average speed is showing as 180MBPS. If preclear can run at this speed then why not my standard writes from windows to Unraid over LAN CAT6 cable ? My file sizes are also not just 1 GB rather generally they are of size 2-3 GB in general.

I have tried many combinations and cant get more than 25 MB/S out of Seagate Baracuda. Refer below thread and if by any chance you can suggest anything then it could be game changer for me. Else all my money spent on these 8 TB drive is waste now.

Johnie, Do you think it could be because of underline 1 SAS connector which is gettign split into 2 SATA Connectors (1 for Parity and 1 for Data Drive) ??

Hi Whipdancer, I was just wondering if you know the reason for slow speed. You meantioned that other thread has an answer but I don't see anything there . Seems everyone is reporting all good with "Model Family: Seagate Barracuda Compute and Device Model: ST8000DM004-2CX188" hard drives.

Thank Johnie. I will do that. Good to know. I know we drifted from original post and it did not get solved but everything i learn here is good for me

Ok let me try to do it and will update others the o/p of same. Is there any link/video available where i can learn what do we mean by new config and resyncing parity ?

Thanks. I am not sure why that old comment also came in when i clicked on "Quote" button. But yes truyl already explained that part. I am thinking to migrate my old server Bootable flash and all disks to new server to ensure that issue is somewhere in drive. In both machines all is same except the hardware and hard drive. So if old hard drives (from old proliant N54L) works at great speed in new proliant ML10 then it clearly mean it is an issue with hard drive . What do you think ? Please share your views ? Also is there any way i can add a brand new data disk with data on it to array without formatting. (Assuming it already is in format "reiserfs") Actually thinking to do reverse as well then. Connect 8 TB drives to old server using unassigned and then copy data, so that my old array is not down for long. Once copied then move this new 8 TB drive to new server , add it to array (Without formatting it) , but rebuild parity. Not sure if this is even possible.

Thanks for trying to help. Dont get upset but as i dont know so will rely on what you said. So is this confirmed based on some diagnostic logs i shared or are you guessing that could be the reason based on your pas experience. ? Hi Johnie. I did not understand what do you mean by Crosspost. So please explain so that i can avoid it. Also how can i get disgnostics please ?

Can you please elaborate what to change and how to change. I am not expert and very basic user of Unraid. Just use it for my media storage nothing more.
