Freenas 9.3 - Intel ICH7 and SATA2/3 devices defaults to SATA1 transfers

[Ed Hornsey]

Hi,

This could be smthg or nothing at all, but thought I'd ask the question to the experts and experienced users on here.

Problem looks to be that the ICH7 SATA 3 controller and FreeNAS 9.3 when combined with any number of SATA 3 devices select an incorrect SATA channel trasnfer rate.

I've changed various combinations in the motherboard BIOS - but has had zero effect on the log. Changed cables too

Thoughts?:)

Please state your hardware. there are a half dozen flavours of the ICH7 alone.

Socket 775 uses FSB -> bad for ZFS
doesn't support ECC -> bad for ZFS
random desktop board -> we don't know what's going on there.

FreeNAS was completely rewritten by ixsystems at version 8. Older versions share their codebase with the nas4free project. Any questions regarding the old versions are best redirected to the #nas4free channel. Due to the legacy code and support for less demanding filesystems it is recommended for older systems (older than 2010).

Holy crap. ICH *7* ?

That's not SATA 6Gb/s, it's very much SATA 3Gb/s. Negotiating SATA 1.5Gb/s is a weird issue. It could be a hardware bug or a derated (Mobile) SKU. First gen SATA 3Gb/s, so it's not very surprising.

Since it's not even close to recommended hardware, you'll have a hard time finding someone with more insight than that. Not that SATA 1.5Gb/s is a problem anyway, few mechanical drives can saturate that.
