Create Mount Point
 

Installed Mint 21.1, Something else. sda7 has my home files. How do I create mount point /home there?

I can mount my home folder from the command line to the Desktop and open its files.

You haven't given many details. Did you have some other OS on sda5 before 21.1? If yes, was it mounting sda7 to /home? Please paste input/output here in plain text form from an X terminal from the following commands after mounting sda7 <somewhere> (e.g. /mnt):

• sudo lsblk -f
• cat /etc/fstab
• ls -n ~/
• ls -n /mnt/.* /mnt/*

mint 20.3 was on /dev/sda5. It was it mounting sda7 to /home.

The command I gave ls -n /mnt/.* /mnt/* was based upon the presumption that you mounted /dev/sda7 to /mnt before running the command, so the above is useless, showing only the content of /. The object of the command was to see if the owner and group numbers matched those of the previous command. Does ls -n on wherever sda7 is mounted show all as owner 1000 and group 1000 as you see in the output from ls -n ~/? If it does, then the output is no longer needed for me to compose a response to the rest of your reply.

can't mount /dev/sda7

How did you try? sudo mount /dev/sda7 /mnt should mount it on /mnt/. What happens when you try to mount it?

All my files are available at /mnt

Are all files 1000:1000 owner:group there, like they are in ~/?

I presume so.

We already knew all in ~/ were 1000:1000. Are they, or are they not 1000:1000 on wherever you have succeeded to mount sda7? Have you been saying that you have never managed to mount sda7 anywhere since switching to 21.1?

There are potential booby traps here by not knowing the answer to the issue of numeric owner:group of files on sda7, but to mount it on /home, boot rescue media and use it to edit /etc/fstab to include the following line:Alternatively, create a login for root[1], then login as root, then perform the edit, reboot, then login normally. This simplistic process will hide all files that currently exist in /home. If those files are unimportant to you, you may login as root and delete them all before performing the fstab edit and reboot.

After the procedure, either from rescue media or via root login, inspect /home/ with ls -l and ls -n to see if your normal username and files are there. If they are, all may be good to go as your normal user.

If there are already files you need to keep in your 21.1 homedir, you'll need to back them up, then after the process of getting sda7 mounted on /home, restore them.

[1] to create root login:

I presume sda7 is mounted. From Nemo I can go to File System click on mnt, open tom and see and open my files that are in ssda7

What do mount | grep sda and df report?

Sorry about all the bother. During the install I did not choose ext4 for sda7 thinking it was already ext4 and selecting ext4 would wipe my files.

That shows you managed to mount sda7 on /mnt. :) So, now you can examine /mnt with ls -n /mnt to see if its content is all 1000:1000. If it is, make the /etc/fstab edit and then then reboot.
