Hi Steven, Thanks for the follow-up. The code where I pulled in zfs trim patches is not updated to 9 stable specially the cam directory. I pulled in many dependent patches in order to apply the patches that you gave. After that all da devices CAM_PERIPH_INVALID in dadone() because read capability was returning a very big number (bigger than MAXPHYS) for the block size. I think this is because I have not update the code to 9 stable (only pulled in required patches and miss some patches). So, I am planning to first update my code to 9stable and then try the same test again. That might take some time. thanks again, ajit On Wed, May 15, 2013 at 2:40 AM, Steven Hartland <killing@multiplay.co.uk>wrote: > ----- Original Message ----- From: "Steven Hartland" > > What version are you porting the changes to? >>>> >>>> What SSD are you using? >>>> >>>> What LSI controller are you using? >>>> >>> >>> I'd also like to see "zpool status" (for every pool that involves this >>> SSD) and "gpart show" against the disk itself. >>> >> >> Also: >> 1.
