I am following the wiki in adding a new drive, and I'm having and issue with hda-diskmount not showing my new drive.

After following the steps again, I noticed something odd when doing 'diff before.txt after.txt' (* the wiki is flawed here, and I'll explain below)

When I run 'ls -l /dev/disk/by-id/' I get the following:

This doesn't seem right, right?

*I believe the wiki is flawed in the following way:

step 1: run ls -l /dev/disk/by-id/ > before.txt
step 2: shut down, add drive, restart
step 3: run ls -l /dev/disk/by-id/ > after.txt
step 4: run diff before.txt after.txt

The expected result is to show the details for the new drive. However, the .txt file's contain a time stamp, and step 2 may take longer than 1 min to complete, so all drives appear in the diff results

Not sure I follow here.

The before.txt should only reflect drives that were connected to the HDA at that time.

If you add a new drive, then start the machine it should not have appeared in the before.txt, only in the after.txt.

So why do you have a listing with two drives, assigned to the same device of sdb and sdb1?

The wiki guidance was developed based on a basic HDA setup. Do you have RAID set up or something else that is out of the ordinary with your hardware or HDA configuration?

I have not heard of any issues before with this guidance, so I am a bit baffled by your results. Please help me understand.

no, I am not doing anything fancy with a raid, just regular drives.

Ok, so what is the drive that's listed twice? I see the prefix wwn in your after.txt but not in the before.

Is the new drive you added in the after.txt at all? I did not see anything, but might have overlooked it.

Posted: **Fri Mar 27, 2015 1:55 pm**

yes, it would appear as wwn-0x50014ee209cbcfed is the new drive.

But hda-diskmount sees no change, and the manual method involves calling off sdX, which is duplicated for me.

Posted: **Fri Mar 27, 2015 2:03 pm**

Well if hda-diskmount does not recognize the drive, then I recommend you follow the hda-diskmount troubleshooting guidance for mounting the drive. The remaining guidance for formatting should still apply to the drive.

The wiki does not appear to be the flaw, but maybe hda-diskmount. If you can provide enough specifics about the drive, it might be worth submitting a bug report so we can explore this more. There might be a need to update the script for a different type of drive or device that we have not encountered before.

Posted: **Fri Mar 27, 2015 2:36 pm**

ok, I tried the manual method, all I am able to connect to the drive now.

odd.... and, thanks!

No problem. Glad it's working for you now.
