Can't add cache SSD

Featured Replies

I'm trying to use a SSD that was formatted on my Macbook, I'm assuming there should be an option to format the drive before adding it as my cache drive the same as there was for my HDDs when I added them to the array.

 

When I try and add the SSD it has

- 128GB SSD

without the ID and as soon as I click it the page just refreshes. There's also no option at all to format the drive.

I am trying to picture just what you are going through BUT I must be missing something. Essentially unRAID should accept the SSD into the Cache slot (while the Array is stopped). When you start the array it then asks you to Format the disk and then all should be well.

 

As a side note, you also need to have the Share(s) configured to use Cache when its all setup.

 

Can you perhaps post a screenshot of your unRAID Main Tab of what you are talking about?

That's exactly what I expected. I stopped the array, shutdown the server, added my SSD, started UNRAID, attempted to add the SSD and it just refreshes the page. There's no option to format it as it won't actually let me add it.

 

Here's a video, it's missing the cursor but I'm clicking the dropdown for the 5th drive and clicking the SDD.

Once I click it you can see the page just refreshes.

Don't know why it won't let you add it, but in the video you are trying to add it as an array drive, not a cache drive. You need to increase the number of cache slots.

Tried that too. Neither the cache or the array will allow me to add it. I get the same thing from adding it in the cache section.

Try running preclear on the drive, skipping the pre and post read. I suspect it is just having some issue with the way it is partitioned or formatted.

How would I do that? I was looking for something that'd empty the drive since it was formatted originally on a Macbook.

Just ran

fdisk -l

and it's not even showing the drive.

Okay, it looks like I've got a dead SATA port. Moving the drive to another port shows the device name and now allows me to use it for my cache drive.
