FusionDrive + Encrypted CoreStorage Volume - Problems writing to volume

Question

Has anyone had experience with encrypted (home made!) FusionDrive volumes and intermittent failure of writes to this disk?

I'm on a Late 2011 MBP 13" with (currently) 4 GB RAM, a 128 GB SSD and a 750 GB SATA disk.

When I'm trying to rsync data (from a TM backup) onto it, I get write failures. I also could not successfully decrypt the volume when I tried.

I have stress tested the disks and they seem fine, and checked RAM, so other than a fault with the drive controller, which I doubt, I don't think it's a hardware problem.

Can anyone post success or similar failures with this kind of setup?

Answer 1

So having done this again it was a problem with the AFP mounted TM volume - why it caused write errors when copying FROM the volume I don't know but I've been running a fusion drive with the same SSD now - without rsyncing any data - for a few months and it's running really well.

Thanks all for your feedback.

Answer 2

It happens to me when I have the SSD at the second bay, all was fixed when I put the SSD at the main bay in order to be shown as disk0
