OK, software RAID is what I need. That eliminates the problems you discussed, plus I can't figure out how to use whatever RAID features exist on the PCIe cards that the U.2 drives are physically mounted on, so to heck with them. My first problem was that mdadm was not installed. This computer has Xubuntu 20.04.1, so that surprised me. But no trouble, apt was happy to install it. But then the problem was figuring out mdadm, which is not a trivial task. Looking at /dev my drives are: nvme1 nvme1n1 nvme2 nvme2n1 nvme3 nvme3n1 nvme4 nvme4n1 I should mention that nvme0 also exists, but it is an m.2 drive that holds / and /home. I started last night by using GParted to create and format one partition of 6.99TiB on each drive, but from the documentation that I have read this morning about mdadm, apparently you do that after creating the RAID, so I deleted the partitions. I think that the following is what I need to create the RAID: sudo mdadm --verbose --create /dev/md1 --level=0 --raid-devices=4 /dev/nvme1 /dev/nvme2 /dev/nvme3 /dev/nvme4 Comments welcome! _______________________________________________ PLUG: https://pdxlinux.org PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
