I then (hot) plugged in each array member one at a time while watching them get detected in /var/log/syslog. I saved the old root drive and put in a new one, installing 20.04 cleanly. Mdadm is much smarter and more forgiving than I expected. What is the best way to rebuild the OS without losing an existing mdadm array?Įdit (end result): From past experience with RAID I thought it was going to be extremely difficult because I didn't have or know the array configuration. I'll be honest, I have no idea how to recover ("assemble"?) the array afterwards or which exact files I should have kept. I do not see a "rescue" installation that would not completely reformat the drive, so I would lose my mdadm configuration in /etc. I don't care about any of the data in /home and ordinarily I'd just blow that away. This system has 1 drive for / and /home and 9 drives for a 56TB array managed with mdadm. I've installed linux dozens of times over the years, mostly on single drive systems for my own use. My system load went to over 4000 and with no other options after a long wait, I rebooted to a persistent kernel panic. to 20.04 but had problems because dockerd could not be stopped. I kicked off a "do-dist-upgrade" from 18.04.
