Today, I received two message for the same cache drive (see below).  I currently have 4 cache drives, I guess is two drives, each with a mirror, all about 240 GB.

 

Anyway, I am thinking I should replace the drive with errors.  Do you agree?  If so, could I just pull the drive with errors and just replace it, considered its mirrored, or do I need the follow the advice on the  wiki?

 

If so, on replacement of the cache drive, do I just hit the mover button after formatting and adding the drive as a cache?

Close but with btrfs that's not how it works, it only means the data is always in at least two drives, but they are not mirrored 2 by 2.

Probably a good idea, but you could also wait some time and if no more errors it should be fine, to replace see here:

Thanks...I have been waiting, but just got two more errors.  I guess I will order a replacment.
