On a Bolt adapter in a system with Ubuntu 16.04, I've formatted the Bolt
for T10 and am using it to do a dd with a 2M block size.
Here are the commands:
nvme format /dev/nvme0n1 --lbaf=1 --pil=0 --ms=0 --pi=2
dd if=/dev/urandom of=/dev/nvme0n1 bs=2M oflag=direct count=1
I get an error on the dd.
root@x1623bp1:~# dd if=/dev/urandom of=/dev/nvme0n1 bs=2M oflag=direct
count=1
dd: error writing '/dev/nvme0n1': Input/output error
1+0 records in
0+0 records out
0 bytes copied, 0.0525061 s, 0.0 kB/s
dmesg shows:
[589997.985151] blk_update_request: I/O error, dev nvme0n1, sector 0
