I'll have to go revisit the archives for your exact fio bits. But I successfully ran our DIX/T10 PI qualification tooling without any errors on the latest SCSI tree. On both scsi_debug and FC hardware. > My colleague chenxiang also tried DIF on 3008 with our same platform, > and we are seeing an issue there also; here's a snippet: Reproduced this. Turns out to be a recently introduced bug that exclusively affects DIF-only setups (so primarily mpt3sas due to lack of DIX support). It's a regression caused by a commit that went in through block a few months ago. I'll send a patch... -- Martin K. Petersen Oracle Linux Engineering
