  válasz mcwolf79 #103966 üzenetére

  Kivételesen egész jó választ adott a google AI, ha nálad valamiért nem jelenne meg, bemásolom, gondolom neked a 3. utáni rész kell. Ha BTRFS-t használsz, gondolom ismered az EXT4-től eltérő mount opciókat. Talán ez a leírás kicsit emészthetőbb,

  Btrfs/Mount Options

  (mindenképp nézz rá googléra, mert a bemásolt szöveg nem elég tagolt, így nagyon nem egyszerű értelmezni)

  To automount a Btrfs filesystem on Linux, you need to add an entry to the /etc/fstab file. This file specifies which filesystems should be mounted at boot and with what options. First, you'll need to identify the Btrfs partition and its UUID, create a mount point, and then add the appropriate entry to /etc/fstab.

  Here's a step-by-step guide:

  1. Identify the Btrfs partition and its UUID: Open a terminal and run the command sudo blkid to list all block devices and their attributes, including UUIDs and file system types. Locate the Btrfs partition you want to automount and note its UUID.

  2. Create a mount point: Choose a directory where you want the Btrfs filesystem to be mounted. A common location is within /mnt or /media, or even in your user's home directory.
  For example, to create a mount point in /mnt, you can use: sudo mkdir /mnt/mybtrfs.

  3. Edit the /etc/fstab file: Open the /etc/fstab file with a text editor (e.g., sudo nano /etc/fstab). Add a new line at the end of the file with the following format:

  Kód:
  UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx  /mnt/mybtrfs  btrfs  defaults,noatime  0 2
  Replace xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx with the actual UUID of your Btrfs partition. Replace /mnt/mybtrfs with the mount point you created. btrfs specifies the filesystem type. defaults is a common option, which provides default mount options. noatime disables updating access times, which can improve performance. 0 2 specifies the dump frequency and filesystem check order. Save the changes and test: Save the /etc/fstab file. You can try mounting the filesystem manually to ensure it works: sudo mount -a or sudo mount /mnt/mybtrfs. If everything works, the Btrfs filesystem will be automatically mounted on system boot.

  Important Considerations: Mount Options: You can customize the mount options in /etc/fstab to suit your needs. For example, space_cache and autodefrag can be helpful for Btrfs.

  Subvolumes: If your Btrfs filesystem uses subvolumes, you may need to specify the subvolume using the subvol=/@ option in fstab. User Mounts: To allow a user to mount the filesystem, you may need to add the user option in fstab. Error Handling: If you encounter issues, ensure the UUID is correct and that the filesystem is properly formatted as Btrfs.

  Example with Subvolumes: If you have a subvolume named @home in your Btrfs filesystem, the fstab entry might look like this:
  Kód:
UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx  /home  btrfs  defaults,noatime,subvol=@home  0  2
