It works fine with ATA drives, but not with NVMe drives. I get the following error # diskinfo -vSw /dev/nvd0 /dev/nvd0 512 # sectorsize 400088457216 # mediasize in bytes (373G) 781422768 # mediasize in sectors 131072 # stripesize 0 # stripeoffset CVFT4291009H400GGN # Disk ident. Synchronous random writes: 0.5 kbytes: diskinfo: Flush error: Operation not supported kern.geom.debugflags is of course set to 16, these drives does not have any partitions either. They also do not show up with camcontrol devlist. What do work though, is creating a partition, ufs file system and dummy file which I can then run this benchmark on. Is this a configuration issue or a bug? --=20 Kind Regards / Med Vennlig Hilsen Olav Gr=C3=B8n=C3=A5s Gjerde BackupBay Gjerde Asalvegen 19 4051 SOLA Norway Phone: +47 918 000 59
