Hi, I have unRaid Server Plus license and was running 8 drives without any cache drive. I was using a modest build and most was using to store my Blu ray rips and was playing them via Popcorn hour media player. The old config was,
- Asus P8B75-M LE Mobo , Intel i3 2100T CPU, Corsair CX500 builder series, - G.Skill RipjawsX DDR3 8 GB (2 x 4 GB) PC RAM (F3-12800CL9D-8GBXL)
I recently moved to a different country and in the hurry i just brought only the hard drives and my unRaid USB drive. If I build a new setup and add these drives along with unRaid USB will it create any problem?
Also I need some suggestions on building a new systems, this time I would add Plex with max 2 streams and probably 1 VM (Linux) and NO gaming. Overall budget around $1000.
Has someone has any build in this price range?
Thanks a lot for your suggestions and input....

Thank you, makes my life easier :-)

Thanks everyone, swap disable worked and i ran a parity check after. It completed with 0 errors. Just one last question, if i change the SATA port of the parity drive or a data drive will there be any impact? Thanks.
-
Thanks for the inputs
-
Thanks RobJ, yes during the second pre clear which reported these errors I did have a power outage, though the server is connected to a UPS, for a second or two I felt the power went off. Basically when the power cut happens (which is often) the generator kicks in 2-3 mins, during this time I have UPS to supply power. Also we are having thunderstorms lately ...

My 3TB drive is precleared and I had to do swap-disable since my current parity is only 2TB. I have been reading the manuals and this is what i think I should do, please correct me if I am wrong.
1. Currently one drive is disabled and drive has been marked as red
2. Select the faulty drive and assign to no-device
3. Stop the array
4. Restart the array
4. Change the current parity from the old parity drive and assign the new 3TB parity drive (sdf)
5. Change the disabled drive - assign the old parity drive
6. Start the array
Is this good enough?

I just completed the second preclear cycle and have Current_Pending_Sector = 2 and Raw_Read_Error_Rate=8, as per the explanation from RobJ above i think this should be ok right? I am planning to replace this drive as the Parity drive. Should I run one more cycle just to be on the safe side?
The "Raw_Read_Error_Rate=8" is not a problem, because the raw value for that attribute is meaningless. What's important is the VALUE for it, 200, which is perfect.
What IS a problem is the "Current_Pending_Sector = 2". As was stated above, that HAS to be zero. If this SMART report occurred right after a Preclear then that is a bad sign. Preclear it again, and if Current_Pending_Sector stays non-zero, I would not use that drive, it can't be trusted.
Just completed the 3rd round of preclear, Current_Pending_Sector has become zero :-) Shall iI go ahead and use this drive?

Thanks, started one more cycle now.

Thanks RobJ, I have started another pass.

Hi All, I am trying to add a 3TB WD Red Drive to my array and the first preclear run just got completed, can someone check and let me know if this is fine? also how many preclear cycle should I run, 20 cycles might take lot of time:-) what would be the minimum safe number of runs?
I got this one line in the final summary, is this a issue? : 1 sector was pending re-allocation after pre-read in cycle 1 of 1.
I started the preclear with this command : preclear_disk.sh -A -M 4 /dev/sdf
-
Thanks , i just placed the order for 3TB drives....
-
Sorry guys one last question. Currently I have 3 data disks and 1 Parity and all of them are 2TB WD Red. While shopping I found some good discount on the 3TB drives. I browsed the forum and found that I can replace the current faulty disk with the parity drive and replace the parity with higher capacity 3TB HDD using "swap-disable". I am running version 5.0.5. Is it ok if I do this? currently the failed disk is showing in Red dot.
If get a 3TB drive and put that in the current parity drive slot and take the parity and put it in the failed disk slot and power up the unit , will it work? Will unRaid identify this change automatically and rebuild the parity and array automatically or do I have to do something.
Thanks again for your inputs.
-
Thanks will do...i just ordered one more Red drive and once it comes will start the RMA
-
Sorry if this a wrong to question to ask, I use unMenu and its a wonderful addon. Out of curiosity i just want to understand the architecture behind this addon. I know that a http server runs in unRaid but want to understand how we do the realtime data collections like HDD, CPU, memory utilization...
Please ignore if this question is not relevant here...Thanks
-
Thanks all for the replies.
Sorry bit confused, is it safer just to RMA this drive or wait and watch if the reallocated sectors are growing?
-
Thanks all your reply. So I will initiate the RMA process. I don't have another drive to rebuild the array but guess i will buy one since i am almost 80% full in the current 3 data drives.
One question, do you think i need to replace the power and SATA cable as well?
Also i paid premium for WD Red drives hoping that they will last long guess this time will stick with WD green drives? any suggestions on the HDD?
-
Thanks a lot again, this is very helpful. I will start with the RMA process, meanwhile someone can check the syslog would be grateful.
-
Thanks, just for my learning how to conclude that the drive is failing. Is there anything to do with me shutting down the server often. I don't keep the server running , switch on only when needed.
Thanks again for the help

Hi, I am unraid noob so please excuse if there are any basic questions. I have been using unRaid for a while and its been great. I generally don't keep my server on and switch on only when needed. After a long time (72 days) I ran parity checked yesterday. Before running the parity check i copied some files to one of disks. During parity check there was lot of read and write errors in one of the HDD and unRaid moved it to disabled state. I checked the cables and restarted the array but it is still in disabled state.
I ran both short and long smart test, I am attaching the syslog taken before the reboot and the smart status report. Can someone please look into it and see if this HDD needs replacement? This is 2 TB WD Red NAS drive and it is just 2 and half years old. I ran preclear when I purchased these HDD.
Thanks a lot for your inputs and help.

This problem is resolved, for some reason Simple Feature was giving some issues. I uninstalled it and now I am able to add the disk to the array. Please check the preclear report and let me know if everything is fine. Also i upgraded to 5.0.5 and Dynamix...

Hi, I just added my 4th drive to the array and completed the 3rd round of preclear, can you please let me know if everything is fine with this disk? I am attaching the preclear finish report. Also having a one more issue, this disk is not showing in the device list and hence not able to add to the array....I had the trail version and recently purchased the plus revision...These are the few reference i see in syslog for the new HDD (SDD)

Thanks Joe, looks like it has some bunch of bad blocks (0.6%), should i continue to use this drive or RMA it?
-
Thanks a lot RobJ, this is very informative, thank you for taking time to write such a detailed explanation. Meanwhile I took HDD out of the array and dropped it in my windows 7 PC and ran HD tune. Not sure if this is a good idea but as you predicated it showed bunch of bad sectors at the very beginning. It has around 0.6% of damaged blocks as per HD tune. Should I go ahead and RMA the drive or run zero pass preclear?.....
Build Migration - Please Suggest

Thank you for the suggestions. This gives me some place to start, any specific X3 people had success with? I will check on the cases, PSU, RAM and get back. I live in Singapore.
