Find swapfile location in Linux Mint












4















I want to increase my swap size to be able to have the hibernate option. First, I tried to add some swapfile. I followed



https://bogdancornianu.com/change-swap-size-in-ubuntu/



and typed this in my terminal:



sudo dd if=/dev/zero of=swapfile bs=1G count=16


I get:



16+0 records in
16+0 records out
17179869184 bytes (17 GB, 16 GiB) copied, 206.949 s, 83.0 MB/s


then, I followed the instructions:



sudo mkswap /swapfile


But I get this error:



mkswap: cannot open /swapfile: No such file or directory


Then, I decided to resize my swap partition instead of swapfile. So I want to delete them. (I didn't create any before so I assume I can delete them all?)
I followed this:



https://askubuntu.com/questions/904628/default-17-04-swap-file-location



I tried:



$ cat /proc/swaps
$ grep swap /etc/fstab


But I get nothing from the first one. Output from the second one is:



              total        used        free      shared  buff/cache   
available
Mem: 11862 3498 1014 138 7349
7907
Swap: 0 0 0


I also tried (after reboot):



swapon -s


and get



Filename                Type        Size    Used    Priority
/dev/sdb3 partition 3905532 0 -2


I wonder that did I successfully create swapfiles? How do I delete them if I did?

The first issue is that your first command created a file, swapfile, in your current directory, and that your subsequent command(s) were explicitly referencing /swapfile, a file called swapfile in the root directory. If that was not your current working directory when you executed the first command, all of the subsequent commands would be referring to a file that is not there to operate upon.



If you got no output from cat /proc/swaps, that indicates that either your system does not have procfs running (unlikely), or that you currently have no active swap space configured.



The output you claim to get from grep swap /etc/fstab makes no sense whatsoever. That looks like the output of free -m (incidentally confirming that you have no active swap configured), not the partial contents of the filesystem table.



Your post-reboot swapon -s (which as the manual states gives the same information as cat /proc/swaps) indicates that at some point prior to your reboot, someone executed swapoff.

    You made a typo:



    of=swapfile


    should be



    of=/swapfile


    the guide creates the swap file in the root directory, whereas the command that you entered would have created a swap file in your current directory.

      Delete the swapfile(s) by



      sudo swapoff -v /?/swapfile 


      where /? represents the directory where you inadvertently created an extra swapfile.



      sudo nano /etc/fstab 


      allows you to edit fstab where you can delete any reference to /?/swapfile



      sudo rm /?/swapfile


      deletes the spurious swapfile.

                            Delete the swapfile(s) by



                            sudo swapoff -v /?/swapfile 


                            where /? represents the directory where you inadvertently created an extra swapfile.



                            sudo nano /etc/fstab 


                            allows you to edit fstab where you can delete any reference to /?/swapfile



                            sudo rm /?/swapfile


                            deletes the spurious swapfile.
