Which do I fix first?

Yes my server is at home
I did need the space. I worked through a guide posted here to accomplish it but it took a while.

root@***:~# cat /etc/fstab

The interwebs indicated that I should use the “blkid” command to show all drives andf their UUID. From this I got the below info. I recall I had a lot of difficulty sorting out the boot drive which was the ssd and it was originally on sda1. when I put in the second drive it became sdb and the new drive became sda. Is the fstab indicating it still thinks its at sda1?

I followed rgis guide on the Yunohost help section to configure LVM

yes

I am a liitle unclear on what you want me to do next. Is it run the command:

grub-mkconfig -o /boot/grub/grub.cfg

as the other poster did or just reboot?
