somehow I4g drives don't like to get formatted
# nvme format /dev/nvme1 -n1 -f
NVMe status: INVALID_OPCODE: The associated command opcode field is not valid(0x2001)
# nvme id-ctrl /dev/nvme1 | grep oacs
oacs : 0
but the LBA format indeed is sus:
LBA Format 0 : Metadata Size: 0 bytes - Data Size: 512 bytes - Relative Performance: 0 Best (in use)
- jeffbee 3y agoIt's a shame. The recent "datacenter nvme" standards involving fb, goog, et al mandate 4K LBA support.
- zokier 3y agoit'd be great if you'd manage to throw together quick blogpost about i4g io perf, there obviously something funny going on and I imagine you guys could figure it out much easier than anybody else, especially if you are already having some figures in the marketing.
