I Installed ubuntu 20.04 with the ZFS experimental option enabled, indeed under disks and gparted I can see that most of my current SSD is occupied by a ZFS_member.
I have very minor experience with ZFS. I set up my zfs in a previous ubuntu 18 install but the OS itself was not on ZFS.
anyways : How do I add another SSD (not the same size or brand) to my current ZFS pool?
I just want the most basic "add space" I don’t really care about x2, x3 or x10 redundancy (in fact I don’t want to alter current ZFS redundancy setup, whatever it is). I just want extra space.
but it doesn’t answer my question for someone of my level.
For example none of the two people who answered specified if it was :
zpool create addonpool /dev/sdb zpool add addonpool mirror /dev/sda /dev/sdb
Or just :
zpool add rpool mirror /dev/sda /dev/sdb#"rpool" name of existing pool, apparently
Nor what syntax is used to point to drives.
all the links I found are referencing syntaxes like :
I can’t find such an identifier, this guide : https://www.thegeekdiary.com/zfs-tutorials-creating-zfs-pools-and-file-systems/
echo | format this does not work in ubuntu 20.04
I do know their guid :

I did test just
zpool alone to get the man, this works so I know that I’d be able to run the above I just want to not mess it up.
Also I’m planning on doing this by logging out and running my commands in a tty. It does nag me that technically at such a point I have not really exited the environment using my ZFS pool so will that work or should this be done from a Live USB?
