Unable to convert cache to RAID1

[Hollish]

Hello community!

 

First time posting here for me, despite reading this forum quite a bit.
I have recently updated my OS to 6.12.6 and added a new cache disk. My intention was for this second disk to be a mirror of the disk that is in place.

The existing disk has been reporting sector failures for some time now.
The issue is that I am unable to convert the two disks to RAID1 mode. I get the error I pasted below.

Does anyone know what to do?

Thanks for your help 😃

sdc is apparently failing, so the balance aborts, run an extended SMART test.

[Hollish]

Thanks for your reply @JorgeB!
I have attached here the extended SMART test results.

 

Is there a way to "force" the creation of a RAID1 setup?

The device failed and needs to be replaced, you cannot create a raid1 with a failed device, since it will abort on the read errors, copy what you can from that pool, then create a new raid1 pool with new devices.

Thanks for your help!
I will remove this drive ASAP!
