Hi all, I have been running extremely well since taking the advice and receiving the support of many on this list. I am grateful those members everyday for its stability. Ed Chan has been an amazing support in creating some backup solutions which have automated the process of achieving efficient data redundancy. I have a Ubuntu 18.04.5 LTS distro with a RAID 1 pair under btrfs.And now I am considering upgrading to another LTS release. Will the commands relating to the RAID survive the upgrade, will the script work from Ed survive the upgrade? In my work as a photographer I find myself in need of GMIC in GIMP, but the latest iteration of GMIC is what I need to recover some work I recently shot. And the latest version of GMIC needs Ubuntu 20.10. Many thanks Andrew Greig

I would expect the RAID configuration to continue to work following the upgrade. I'm obviously not familiar with the contents of the scripts, so I can't be sure, except to say that the Linux command line interface and directory hierarchy tend to remain fairly stable across distribution releases. If you have a good backup of everything, you can always downgrade if there are problems, or resolve them after the upgrade if they aren't too severe.
Hi Jason, Thanks for your quick reply. I will ensure the back up first. thanks Andrew On 29/11/20 9:45 am, Jason White wrote:

Yes, I've upgraded Debian BTRFS systems since 2012 without any problems and as Ubuntu is based on Debian it should work the same way. BTRFS supports the subvol= mount option, so you can mount a subvol as root. You can make a read-write snapshot of root, upgrade the regular root, and then boot from the subvol if something goes really wrong with the upgrade. Also you can use systemd-nspawn to run a chroot environment if you need to use old versions of apps. I have old distributions running with systemd-nspawn and ssh to them to run older apps. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
