Using the following hardware:
The plan is to create a RAIDz3 zpool with 20 disks in the array, 3 hot spares, a mirrored log device containing one drive from each of the ioDrives, and two cache devices made out of the remaining ioDrives. We'll also underprovision the ioDrives to help with wear leveling, since 320GB ZIL and 640GB cache are excessive for this setup.
We're going to add ZFS support to our Oracle Linux installation. We'll just add the ZFS on Linux Repo, verify the binary signature from GitHub, install the files, ensure the driver loads properly, and verify that it's functional. We'll save things like array creation for another document.
This is mostly a transcription of the process from the CentOS/RHEL ZoL installation manual.
This will install ZFS v0.7 release on OEL 7.7 and earlier, and ZFS 0.8 on OEL 7.8 and later.
This process is an outline of the steps I followed to get my two first-gen 640GB ioDrive Duo cards working on Oracle Linux 7. After we install the driver, we're going to perform the optional step of formatting the cards to use native 4k sectors, since it offers marginally better throughput and a decent reduction to memory usage.
Go to the SanDisk support site and download the packages that correspond to your device and kernel. I'm using 64-bit Oracle Linux 7.
On the support site, we pick out our device,
We download the latest release of pfSense as a gzipped ISO, then extract it and pass it to virt-install to get the VM up and running. Interactive portions of setup are handled with a VNC viewer because the pfSense installer doesn't seem to be able to work with virt-install's native console redirection, at least not out of the box. I'd love a tip from anyone if it's possible to fix that somehow.
CentOS 8 instructions are this way.
