Hello,
I have Solus 4 (love it) installed as my main OS on my desktop. Specs are: AMD Ryzen 7 1700, GTX 1060, Samsung SSD 960 EVO 250GB (nvme0n1). I have recently installed a 1TB SanDisk SSD, and I'm wondering if I can use this new disk as my default home directory (i.e. / home). So far I tried the following:
First, I mounted the new disk and copied everything from my home directory to it using rsync -aHAXvP ,
then I added the following line into my /etc/fstab :

UUID=<New-Disk-UUID> /home ext4 rw,relatime,errors=remount-ro 0 1
Then I have manually assigned the new SSD to /home and restarted my machine. However, I can't get past the login screen. i.e. I do get the prompt to input user name and password, but login fails and it enter an endless cycle of asking me again to enter login info.

Can anybody help me out with this? Thank you.

Did you remember to remove the # and "'s from the fstab UUID edit. 🙂

    CraigMatze Hi, thank you for your reply. Not sure exactly what you mean, but the line I added has no # or quotations. Do you mean I need to uncomment other lines?

      Well, boot up single user mode (if you know how or can research) or off live CD/ISO and figure out what you got wrong.
      Consult dmesg, journal, and double check everything (which you should have done before rebooting).
      Good luck.
