Replacing a Failed drive in MD RAID 10

How did you figure out what drive it was in the array? Or did you pull them until you saw the one with that serial number?
How do I know which disk it is?
Well the other day I noticed that the array had a failed disk. Since I was rebuilding the system anyways I pulled each disk and performed a check disk from windows while checking for bad sectors.
Only 1 disk was found with bad sectors.
Knowing which disk this was, and windows saying it fixed the problem, I re-added the disk and simply "remember" which disk had the bad sectors.
So this disk is the disk that has to be removed.
Ok, so you wouldn't be able to figure this out from the Linux CLI you would have to have a record of all the serial numbers that are in each bay.

@coliver Pretty much.
Since there is no hot-swap function on my server (no indicator lights either) it's simply a matter of my knowing which disk is connected to which SATA port.
-
So at this point I have the disk marked as failed, and removed from the array as shown below.
As you can see sdc is not a part of the array at the moment, which means nothing will be written to the disk. Obviously I'm in a dangerous point in time.
If I can't get my replacement disk soon, I risk losing the entire array.
Now, because I've ready had issues with this array (specifically the disk) I have nothing running on this system that I don't have several backups of. So the drive has been ordered and will be here in a day or so.
At which point I'll shutdown the server, remove the bad disk, and put the new one in.

While I wait for that drive to arrive, I'm going to figure out how to configure email alerts for the mdadm array. Seeing as this would be incredibly useful to have.
Since I can't sit here watching the cat /proc/mdstat....

No remote ssh access?

@travisdh1 I do have access, but I'm still not going to sit here and watch it.

So now that I have the email alerts configured for my Xen Servers, I really want to work on updating SmartCTL so it supports the drives that I have in this server.
Which are pretty common drives.
Western Digital Red 1TB.
I'm really surprised how old of a database is built into XenServer 6.5.
So time to figure this part out.
