Hi folks. Seems like I am having multiple issues on my server logfiles attached. All help is appreciated. Thank you in advance. How should I go about recovering? 

1. Disk3 has failed 
2. I cant read the files on disk 3 (emulation seems to fail)

3. Disk 4 has some errors 

4. Fix Common problems is reporting the following: 
 

disk3 (ST3500641AS_3PM1YPT7) is disabled	Begin Investigation Here:
disk4 (ST3000DM008-2DM166_Z5059TES) has read errors	If the disk has not been disabled, then unRaid has successfully rewritten the contents of the offending sectors back to the hard drive. It would be a good idea to look at the S.M.A.R.T. Attributes for the drive in questionBegin Investigation Here:
Unable to write to disk3	Drive mounted read-only or completely full. Begin Investigation Here:
Unable to write to disk4	Drive mounted read-only or completely full. Begin Investigation Here:
Call Traces found on your server	Your server has issued one or more call traces. This could be caused by a Kernel Issue, Bad Memory, etc. You should post your diagnostics and ask for assistance on the unRaid forums

removing file

Another problem with a SASLP, you'll wan't to get rid of that controller, rebooting should get your data back, you'll still need to rebuild the disabled disk, I would recommend if possible replacing that controller with an LSI before trying.

Sorry another problem with SASLP? not following. 

Fix is to reboot? 

And again sorry what is a LSI? 

You mean I have a bad SATA card from SASLP that I should replace with a card from LSI? Any particular model? 

It's a reoccurring issue for users with both SASLP and SAS2LP, they are not recommended for unRAID v6 for a while now, rebooting will likely fix the problem for now, until it happens again, and you'll still need to rebuild the disabled disk.

 

Recommended HBA is any LSI with a SAS2008/2308/3008 chipset in IT mode, e.g., 9201-8i, 9211-8i, 9207-8i, 9300-8i, etc and clones, like the Dell H200/H310 and IBM M1015, these latter ones need to be crossflashed.

Thank you very much. 

Is this a good one? or is there a model you recommend that is better.

To clarify - Rebuild disk 3 and disable disk 4? 

 

Disk4 should come online after a reboot (or power cycle), then rebuild disk3.

Johnnie Black - Thank you very much. A shutdown restart worked. I had tried a reboot - before i posted - that didnt work. 

I appreciate your help. 

 

Is there a replacement card you recommend? 

ok spoke too fast. 
After the shutdown restart I was able to start to copy the data out of Disk 3 - I am planning to turn that old drive down and not replace it since I have a lot of unused space on my server. 

a bit into the copy the I get read errors - so I am thinking I have to replace this card first before trying to get my server back to where it used to be - now 4 drives are reporting read errors - I am guessing its the card. 

Could you please recommend the most reliable card I can purchase? 

Thank you. 

ps. New diagnostic file attached. Just in case its some other problem.

Yes, errors on multiple disks, all connected to the SASLP, so looks like problems with the controller again, I would recommend shutting down the server until the replacement arrives to avoid more damage.

 

The controller you linked will work fine.

 

 

 

 

Thanks ordered the card - will update the thread. 
 

Card came in. 
Installed. 
Data copying no issues so far. 

I want remove the bad drive  - ie: not replace it. 

This is the instruction I found to do that: https://lime-technology.com/wiki/FAQ_remove_drive
sDoes not talk about version 6.x 

I want to remove the drive, replace with a new one and use the new drive to be second parity drive. 

Do I just follow instruction to remove, then add new drive and assign it to parity 2? 

Here's the wiki you want:

 

https://lime-technology.com/wiki/Shrink_array

 

Just use The "Remove Drives Then Rebuild Parity" Method but at step 7 in addition to unassigning the drive to be removed, also assign the new parity2.

Thank you

Thank you trurl and johnnie.black. 

Added a new HBA

Removed Disk 3
Added a new drive and made it Parity 2
