Want to allow disk space to /boot, or want to boot from other disk (16TB)

Hi there,
I am new in Linux system. Here is my disk space details(attached). Whenever I want to login as user the system just doesn't give any response but I can login as root. It seems my /boot disk hasn't enough space. How can I allow disk space to the /boot (I have enough space in the 16TB disk). Is there any way that I can login through 16TB disk (/dev/sda1)?

Can you please provide a bit more information? For some reason you think that you don't have enough space in /boot and that this is somehow leading to your normal user not being able to log in. (I don't see how these two facts should be related, but I might be missing something.)

For people to be able to help it would help if you gave a bit of background info.
What distro are you using?
How are you trying to login? (Are you physically sitting in front of the computer or are you logging in remotely, e.g. through ssh? Are you logging in on a terminal or are you using a graphical login manager?)

You do have enough space in /boot, and even if you didn't that would have nothing at all to do with logging in as a regular user vs root. We need a lot more information as joe mentioned.

I am using the following system: Initially I had 64 Gb memory. Then I added extra memory. After added the memories I lost the GUI (maybe there was update issue with yum). Then I downloaded and installed "NVIDIA-Linux-x86_64-331.67.run". Now the GUI is working. But I can't login as a user in the desktop using my ID and password. But I can login through ssh using the same username and password. I also can login as root and I can access all of my files. But I don't want to login as root. I am new in the system administrator arena. Would you please to help me.

Best Regards

scrap that, misread your post

here is the 16tb disk.

I am trying to login directly, not remotely.

Why are you trying to mount /dev/sdb1 to /home in your fstab? sdb1 is a 500M boot partition, it should NOT be mounted at /home. Unless you have a good reason for doing that, which I highly doubt, delete that line from your fstab.

Probably your user is no member of video group ... just guessing.

/dev/sdb1 /home xfs defaults,usrquota,grpquota 1 2

So, I just need to delete this 3rd line only from /etc/fstab? And anything I need to do?

I want to mount /dev/sda1 as /home. But don't know how? Would you please to help me.

what is a video group? How can I include my user in this group?

What is confusing is that the output of the df command shows /sdb1 as /boot but the attached image and your /etc/fstab file show that sdb1 is also mounted as /home. If your /home is also on your /boot partition then that could be the reason why you can not login because your also using quotas and it is only 524MB.

Post the output of the command blkid. This will show all of your filesystems information i.e. partition, file system type and UUID.

Yes absolutely remove that line and see if it fixes your problem. Once your system is functional, we can go through migrating /home onto your 16 TB array, I've done it many times.

Yes, then reboot. Or you could comment the line out by putting a hash mark at the beginning of the line as shown below and rebooting. You could then put a comment on a line above it explaining the problem and why it should not be done for future reference.

As pointed out above, you have boot and home mounted to the same partition but it is actually just the boot partition. You have a home mount point in fstab of sdb1 and if you look at the blkid output, the uuid for boot is sdb1. That will be nothing but problems.

If what you are trying to do is get home mounted as a separate partition on sda1, the simplest way to do that is to create a separate partition for it during install. You could create a mount point for sda1 now then create a proper entry for it in fstab and copy the home directory and its contents there. Since I've only done that once, I'll leave it to others to explain how to do it.
