How to reproduce

Used the guide from here: https://forum.proxmox.com/threads/configuring-fusion-io-sandisk-sx300-sx350-and-px600-cards-with-proxmox-6-1-kernel-5-x-tested-up-to-5-6.68642/

I'm using SDFADAMOS-3T20-SF1

Possible solution

I assume there is a hard limit of how big the drive can be and 3.2TB exceeds it.

Environment information

  1. Linux kernel compiled against (uname -a): Linux dc6 5.4.60-1-pve #1 SMP PVE 5.4.60-2 (Fri, 04 Sep 2020 10:24:50 +0200) x86_64 GNU/Linux
  2. The C compiler version used (gcc --version): gcc (Debian 8.3.0-6) 8.3.0
  3. distribution, and version (cat /etc/os-release): Debian GNU/Linux 10 (buster)
  4. Tag or Branch of iomemory-vsl4 that is being compiled: v5.6.1

The drive can be formatted with reserve space for performance reasons. Chances are your card has been formatted to a reduced capacity. In your case this would probably be ~25%, as that would add up from 2.5TB to 3.2TB. Please have a look at page 31 here

Thank you, @snuf!

As always, you're very helpful! After some digging i arrive to the same conclusion. Glad the drive is ok and glad the drivers seem to work fine! :)
