Drive issues

[dodgeman]

Well after moving motherboard to a new chassis, I ran into a overheating issue at night, and now I have a situation where the only way to get the array online is with 1 parity drive out of the array, and 2 drives while installed show up under unassigned devices. I can add new drives to the pool for either the parity or the file system. Is there a way to rectify this without starting over ? I ran XFS check on the drives and they had not issues, I also read them on another system and pulled them to protect the data but I cannot put in replacement drives to rebuild the array. I went through the what to do with file system issues but I cannot find a matching issue to address this.

I must admit I am confused by your description  

 

Perhaps posting a screen shot of the Main tab and your system diagnostics zip file might help make it clearer?

The disks not installed show up in the unassigned devices tab. I tried the drive connected to the backplane and to SATA ports on the motherboard, trying to removing cabling and controller issues.

Do you mean you ran the check on the drives while they were not in the array?

Do you mean you made changes to your disk assignments that left disks out of the array? The screenshot shows the array started but with the emulated missing disks unmountable.

 

Seems like you need to tell us in more detail exactly what you have done before we can make any sense of this.

After the machine booted the drives were listed as not installed. I looked under unassigned and they were listed there. I then ran XFS check and found no issues. I then shutdown and moved the drives from the backplane to SATA cables. They still showed up in unassigned and you can view the data on them. I pulled the drives from the system currently and I tried to replace them but that is not an option as the array is listed as an invalid configuration when I add new disks.

You have two disable disks with single parity, it's not possible for Unraid to emulated them, if the disks are OK you can do a new config and re-sync parity (or check parity is already valid and run a correcting check).

[dodgeman]

Could you point me in the right direction to start that new config/parity sync.  Yes the drives are fully readable with no SMART issues being reported.

-Tools -> New Config -> Retain current configuration: All -> Apply

 

Then start the array to begin a parity sync or since parity should be mostly valid check "parity is already valid" next to array stat button before 1st array start and then run a correcting check.

JorgeB Thanks that was exactly what I was looking for.
