devices which just uses a size in blocks or some such, or all that nasty geometry stuff should be consigned to the dustbin of history.
Amen. Can I sign up for that religion ? I'd sacrifice a candle and burn a chicken ... or some such.
However I doubt anyone is in a hurry to modify such a key utility.
Well, yes. We're extremely aware of the pain the sd driver's reliance on "geometry" causes. And the confusion/frustration to users. The one and only reason why this isn't simply ripped out and consigned to the big pile is compatibility - how do you upgrade a system that e.g. has 10000 SVM or VxVM volumes, if all device numbers for sd nodes underneath change as a consequence of the upgrade ? This is like an attempt to transplant a pig's heart for a monkey's, done without anestethics ...
First step was moving the "labeling" code (partitioning) into the cmlb driver. The dadk and cmdk target drivers already have no more "geometry" stuff in them. Work on sd (second largest sourcefile in Solaris) to change it to use cmlb as well is still going on.
MrChuck PS is this project still alive?
iSCSI for S9 ? No idea, sorry. FrankH.
