We currently do 2GB per command on ATA and 2TB per command on most SCSI targets. I don't disagree that it may make sense to have a disable discard option to mkfs. But Roland really needs to get his VPD reporting fixed. I suspect what the array meant to communicate was a 1MB discard granularity, not a 1MB per command limit...a common mistake. -- Martin K.
