    You should read these recovery methods when you get linux fstab page file error.

    Here are the steps to replace the file:

    Should swap be in fstab?

    The fstab entry is recommended when the swap partition on the device is managed with GPT. See next subsection. If you are using this TRIM-enabled SSD, consider selecting the delete option on the swap line as part of fstab. If manually enabling paging is reason enough to paging, using the -d / –throwaway option achieves the same result.

    sudo mkdir -p /var/cache/swap/ # Organize directory containing alternate filesudo dd if=/dev/zero of=/var/cache/swap/myswap bs=1M count=4096 Count for 4 GB

    Of course, there is another way to create a data file of a specific size.

    How do I add a swap file to fstab?

    Detach existing swap space.Create the newly created swap partition suggestedsize.Read the partition table again.Set up a partition for swap space.Add a new section /etc/fstab.Rotate to swap.

    sudo chmod 0600 /var/cache/swap/myswap # Only basic tasks should have accesssudo mkswap /var/cache/swap/myswap number format like swapsudo swapon /var/cache/swap/myswap Say the system number

    Insert the following sentence in /etc/fstab to skip the next real boot:

    /var/cache/swap/myswap none of these swap sw 2 0

    Note. If a person has system files on a real SSD, be aware that you store the swap file in a specific location on the hard drive.

    Note: You cannot use the swap list to hibernate (see Ubuntu SwapFaq)

    Extra knowledge for Ubuntu >= 17.04: Swap in /swapfile withSet by default on a new mount (if there was no swap partition). We can replace the correct section manually later if we want.

    How do you swap files in Linux?

    Create a swap file: sudo fallocate -n 1G /swapfile.Only the root user should be able to write to and read from the swap file.Use most mkswap utilities to set up our own file as Linux swap: sudo mkswap /swapfile.Enable swap with all of the following commands: sudo swapon /swapfile.

    Then remove the swap entry from /etc/fstab or replace it with a new alternative.

    1. I have a Linux partition on my main drive (medium sized SSD shared with Windows). There are
    2. i another Linux (ext4) partition on the hard drive. It is almost certainly permanently mounted in /etc/fstab.
    3. I didn’t create a swap file on the root drive to save space.

    How do I enable swap on fstab?

    Exit the terminal and run gksu gparted & and enter your root details.Right-click the swap partition and select *Information*.Run gksu gedit /etc/fstab and find the network containing *swap*.Save file.Activate the new configuration section with this command.

    So I’m asking you to create a disk partition swap file associated with the disk. I’ve created and enabled the active exchange properly, but I’m having trouble getting it permanently included in /etc/fstab. Should it be mounted in /dev/ (wheremounted pump) or /mnt/ (where my filesystem is mounted)?
