Doing some fast-paced benchmarking of lots of raid levels, some in a kvm, some via RDMA access over InfiniBand using different procotols, etc.
Was shocked to see horrible raid0 performance in one of the tests. Looked back through the logs and found: (Note that I typo'ed -d raid**e**0 ===== $ sudo mkfs.btrfs -f -m raid0 -d raide0 /dev/vda2 /dev/vdb1 /dev/vdc1 Unknown profile raide0 btrfs-progs v4.1.2 See http://btrfs.wiki.kernel.org for more information. Label: (null) UUID: 6a49602b-2edb-46aa-b602-352c5257284c Node size: 16384 Sector size: 4096 Filesystem size: 108.00GiB Block group profiles: Data: single 8.00MiB Metadata: RAID0 3.01GiB System: RAID0 19.94MiB ===== It defaulted to using a single drive for data. I think having it do nothing and give an error would be better. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
