Hello everybody. There was a need to create swap. There was no free partition, so I decided to create swap in a file. I did everything according to the instructions As a result, it was done:
dd if=/dev/zero of=/swapfile bs=1M count=4096
chmod 600 /swapfile
mkswap /swapfile
swapon --discard /swapfile
Also added an entry to fstab. swap immediately determined. After a couple of minutes of work, the kde graphical shell fell. I tried to turn off / restart the PC through the terminal, to which I received that the argument of any of the commands is incorrect. Made a hard reset. After starting the PC I get:
:: Loading keymap...done
:: mounting '/dev/sdb2' on real root

mount: /new_root: mount(2) system call failed: Structure needs cleaning.

I tried to run fsck.f2fs /dev/sdb2 through the Linux Mint live mode. What did I get a huge list of damaged blocks for, after which I asked whether to restore files from ./lost_find? Answered Yes. As a result, the recovery failed. I hope there is an opportunity to save my FS.
upd: When asked whether to restore files, answered no, after asking whether to restore the partition - answered yes, then asked whether to restore files - answered no. Posted by Done. The partition is still not mounted, but at startup it now writes

G'day ForumLiker, and Welcome to

How much RAM do you have ?

It is possible to do without any swap space etc, if you have sufficient ram.....and thus avoid all that drama

eg, I am running Linux Mint with 16GB of ram, no swap space etc

no resulting problems or dramas
