Use these steps as guidance, not a copy & and paste template. Device names, partition schemes, size and who knows what, WILL differ on your system. Device and partition duplicationĪs mentioned above, these steps were performed on a VM, not an actual Gen10+. The practice VM could successfully boot from a single drive if there was a failure.The copy & paste verbiage below is from a VM I practiced on.What will happen in subsequent updates of Ubuntu if packages touches /boot/efi is unknown at this time.What works on my computer might not work on yours.

I hereby present the 100% unofficial guide on how to transfer a Ubuntu 20.04 installation from a single device to two devices, mirrored. Going from single SSD to two NVMe drives in one swift stroke. My Google Fu completely failed me and I could only find obscenely written guides or vague evidence on how to do this and I decided to DIY since my situation was fairly unique. Friends don’t let friends to OpenZFS on RAID, so I would end up doing post-install surgery and I simply took the challenge of doing in-place replacement of the SSD onto a NVMe drive and make the OpenZFS pools mirrored (there’s one boot pool and one system pool with the default Ubuntu install).

If so, would I install on a RAID1 or try cobble the disks together with OpenZFS pre- or post-install? (Ubuntu installer does not yet support any advanced OpenZFS pool schemes, AFAIK). The next decision I had to make was if I had to reinstall the system on these drives. Said and done, I picked up the StarTech PEX8M2E2 adapter along with two 1TB WD Blue SN550 M.2 2280 NVMe drives.Įdit: As snarled at on reddit, bifurcation is not needed with the StarTech card. Since the Gen10+ has a spare PCIe slog, it’s possible to put two NVMe drives using a PCIe to M.2 adapter card. External drives? USB? eSATA? SAS? Thanks to the extremely well done research by Serve The Home, I did not have to look far.

Since I don’t have two 2.5' slots to spare for mirrored boot and home directory, I needed to get creative.

Bye-bye, SK Hynix, you are the absolute worst. I opened a support case with SK Hynix who got back to me with the very unexpected response that I should install Windows. Sometimes it performs well and sometimes it’s single digit throughput (MB/s). Unless, the unexpected problem, the SSD comes to a screeching halt at times, for no apparent reason. I’m not a huge fan of keeping this data on a single drive either, as I had planned to move my home directory over to the SSD and just keep copies of the home directory on the spinning media pool. It’s like being back at the late nineties. The former problem is that I have my home directory on the spinning media OpenZFS pool, this, by today’s standards, is quite dreadfully slow, given I serve my home directory over NFS in certain situation. Two problems presented themselves, one I could predict, the other a bit unexpectedly. The remaining three disk slots are used for my spinning media OpenZFS pool. As boot drive, I put in a SK Hynix Gold S31 SSD in one of the 3.5' slots using an adapter. I’ve blogged about my HPE ProLiant MicroServer Gen10+ in the past.
