Were you running the check from the GUI or the command line?   If the command line what was the exact command you used as it is easy to get it wrong?

I am using it from GUI

start array at maintenance mode, select disk3, and check file system status..
the quote is the result of the check file system, and fix button showed up

Maybe we can get original 10TB parity to emulate disk3. Is original 10TB parity still plugged in?

no, so i plugin 10 TB parity disk, start new configuration, and emulate disk3?

Just to make sure nothing unplanned happens, go to Settings - Disk Settings, and set Enable autostart to No.

 

Then shutdown, plug in original 10TB parity disk. You can remove new 12TB parity if you need to.

 

Then reboot and post new diagnostics.

 

Don't do anything else without further advice.

Go to Tools. New Config - Retain All - Apply.

Assign 10TB parity, I think new disk3 should still be assigned and all others as before.

 

Very important! Check Parity valid checkbox so parity will not be rebuilt, AND check Maintenance mode checkbox so no other disks are mounted.

 

Start the array. This will accept all the assignments without doing anything else.

Stop the array. Unassign disk3

Start the array in normal (not maintenance) mode. This will disable and emulate disk3.

 

Then post new diagnostics.

Emulated disk3 is still not mountable.

 

Check filesystem on emulated disk3 (the empty disk3 slot, not the unassigned disk) from the webUI. Post the output.

We missed in this screesmnhot, and I guess you too, that there were read erros on disk4 during disk3 rebuild:

Then can be seen on the syslog-previous from the next diags:

Disk4 is failing, so disk3 rebuild is corrupt, I'm array that the array is in a very precarious situation, and some data loss is likely.

Then can be seen on the syslog-previous from the next diags:

Disk4 is failing, so disk3 rebuild is corrupt, I'm array that the array is in a very precarious situation, and some data loss is likely.

so what is next step? replace both disks?

You can't do that with a single parity, best bet is possibly trying to clone both failed disks with ddrescue to see what can be recovered, then rebuild parity with the clones.

I am thinking my option.
A. If i just plug 2 new harddrive, what is the risks of losing data, both drive or part of data? and I will just copy manually from both drive into unraid array.
B. I'm not good at linux, but i am confident when i learn it step by step (cannot do it on unraid because limitation on storage attach). Because of disk3 is new harddrive, so
1. clone disk3 previously 2TB into new 4TB
2. clone disk4 with new harddrive,

3. plug both into array and let rebuilding again? with smaller data loss compare to point A?
Thank you

ddrescue is IMHO the best option to save the most data, but note that if the clone is larger than the original disk, you will need to upgrade to Unraid 7.1, or the cloned disk won't mount.

noted, I am thinking
1. clone disk4 with new HDD4TB (can i use clonezilla because only familiar with it, as my unraid licence limited to 6 storage, and I have to setup another machine for ddrescue)
2. plug clone hdd 4TB  as disk4 and 10tb original parity to disk3
3. parity drive 12TB as previous

So it is still the same as previous plan I think.. Thank you for your patience, :D

ddrescue was made specifically to recover the most that possible from a failing disk, it does multiple passes, backward and forwards, clonezilla will likely not be able to recover as much data.

Thank you, I'll install linux then.. :), and updated when there is possible

Sorry to keep posting, i have been thinking, if I unplugged all the drive but the disk3 and new harddrive, can I use unraid as ddrescue, then after finish I rearrange and plug everything back? and start the array?

Thank you

BTW, to run ddrescue you don't need to start the array.

So you don't need to remove any disks.

Thank you, ddrescue on progress

Hello, ddrescue is finished for disk4, should I continue the script below?

Quote

printf "unRAID " >~/fill.txt

next

Quote

ddrescue -f --fill=- ~/fill.txt /dev/sdY /boot/ddrescue.log

and this script?

Quote

find /mnt/path/to/disk -type f -exec grep -l "unRAID" '{}' ';'

can you guide me as I am a newbie,  Do I type the script in unraid terminal?
and the third script, how do i mount it? restart the unraid or start the array and mount disk4 with unassigned disk devices? or installing UD plugin, and then 
I still confuse about this guide, what is correct mount point, 

Quote

Replace /path/to/disk with the correct mount point, all files containing the string "unRAID" will be output and those are your corrupt files, this will take some time as all files on the disks will be scanned, output is only displayed in the end, and if there's no output then the bad sectors were in areas without any files.

currently the source drive is /dev/sdb

and cloned drive is /dev/sdc

thank you for your answer

Post the clone results first.

Here is the results, hope it is readable, I cannot screenshot because I connect to unraid directly
