Hi,

 

Unraid 4.7.  Disk 3 showed redball, so I stopped the array and hot swapped for another identical drive.  I updated in Devices and when I went back to Main, Disk 1 shows that it is missing.  I double checked the configuration, unassigned it, reassigned it, reseated it, rebooted the server, swapped the sata port, and still it shows that disk 1 is missing.

 

Syslog attached, screenshots below.  Please help!

Try this: if you try to change the "unassigned" to a new drive, do you see your drive as an option to add ?

 

BEWARE: Only see if the option is there, do NOT actually assign the drive !

 

Chances are that your drive's size has changed as far as unraid is concerned, then it will not be recognized as the old drive.

 

Post back results !

Are you sure 4.7 supports hot swap? Somewhere in the back of my head I'm remembering hot swap after stopping the array (warm swap?) being added as a feature in the 5.x series somewhere?

Thank you for the reply.

 

It does allow the drive to be assigned.  I did not assign it to a different slot.  How can I verify what unraid is expecting for the size vs. the current size?

I am not sure, but I have done it multiple times in the past and the hot swapped drive seems to be working fine.  It is the other one that is giving me fits.  I can shut down from now on.

I didn't believe 4.7 supported hot-swap either. Try a reboot.

A soft reboot was performed after the other steps (unassign, assign, reseat hard drive, reseat sata connections, switch sata port).  The system shows the same status after each action.

Issue is that unraid thinks the drive is missing, that is because it sees the old drive as a new drive. Identification is done based on several parameters, one is size. In some cases bios updates, a bios setting, change of a sata port, can lead to a size getting reported differently, if you can imagine what that was then reverse it and it will work, if you cannot think of what caused this then you need the fix for it.. I am not sure what it is but it is here, search the forums (i\ll do the same tonight)

Might be time to contact Limetech.

 

Otherwise, I would make a new USB stick and try booting that just so I could check the drive. Use the new RC because 4.7 can mess up the MBR of existing drives when using a new USB stick.

 

See attached, this could be your issue:

Your syslog shows HPA on ATA9, this is a Maxtor 6L300S0, BACE1G20, max UDMA/133 but that is not the EARX you are having the issue with... So I guess this HPA thing is not your issue... sorry..

 

I don't see HPA as the issue. There is a HPA on the Maxtor drive, but that's not disk1.

That would be to get the actual drive size to compare against the previous and confirm that is the problem, correct?

And also just to build a 1-disk or 2-disk array with the drives and confirm if they are ok or not. You could also comfirm if the failed one really failed.

IC, Adding a drive to a second install like that doesn't change the drive data as long as I don't spin it up, right?

Got into unMenu and I can see the drive, and it shows the right size.  :-|

 

Notice though, the name is missing the P in the image.  That is strange...

Ok, still not sure what was going on, but I fully shut down and left it for about 10 minutes, and ran through a cold boot cycle.  When it came up, it looked exactly the same, but no disk was assigned to disk1.  I assigned it, and all of a sudden it is found and ready to come online and start the rebuild.

 

When in doubt, reboot (again and again)

 

Thanks for all the help guys, seriously.  I really appreciate it!
