According to release notes, gmirror TRIM is supported since 9.1R. I did a little test on 9.2R livecd environment with commands you stated in previous mail. Both amd64 & i386 work. 2 md devices were used as backend device, but it should not differ since gmirror reports 'candelete' attribute regardless of backend capability. The above seem to conflict with your result on 9.2 test machines. Could you confirm that? Maybe there's something missing. Regards, Jia-Shiun.
