Steffen, > There are too many unresolved issues with DIX outside of zfcp such as > wrong protection data on writesame/discard (over device-mapper) We don't configure protected transfers for anything but read and write commands. There is currently no protection information generated for WRITE SAME. So if you guys are seeing failures, it must be due to zfcp not handling the scsi_cmnd prot_op/prot_flags or the command PROTECT bit correctly. > or due to unstable page writes. BDI_CAP_STABLE_WRITES should take care of this. What's the configuration that fails? -- Martin K. Petersen Oracle Linux Engineering
