[OpenIndiana-discuss] info about Solaris and the new 4K-Sector-Disks (e.g. WDxxEARS)

[Piotr Jasiukajtis]

That PSARC is already included into OpenIndiana:

summary:     PSARC 2008/769 Multiple disk sector size support.

I guess the issue here is little misunderstood by the community. 
Solaris/OpenSolaris/OpenIndiana is ready for 4k drives and it uses 4k if drive report that.
The case with WD EARS is the drive emulates 512b sectors (it reports 512b instead of 4k) while it's 4k native.

Take a look at related bug report: https://www.illumos.org/issues/453
and proposed solution: http://lists.illumos.org/pipermail/developer/2011-January/001218.html

This seems to be a fairly generic and flexible solution, however it will only be available in the next release of Solaris. It might be already integrated into OpenSolaris"
