Hello, I just tried to run the recently added slog benchmark for
diskinfo on 11.1-Release. 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?
