What do you think about it?

So you have 64GB SD card with three partitions on it, say an EFI partition, a boot partition and a LVM physical volume (PV). Unlocking the volume makes it appear as block device in Gnome Disks, and you see that the volume contains a 62GB XFS file system. Nothing seems strange to me.

How do you remove the SD card from your laptop? You may want to …

  1. unmount the xfs file system (on the square, white stop symbol)
  2. lock the LVM storage (PV) (lock symbol)
  3. eject the 64GB Drive (which unmounts all partitions of the drive) (eject symbol in the upper bar)

When I remove the sd card from the reader, a 62GB volume remain,

That is likely a bug in Gnome Disks.

after removing the SD card, run lsblk from command line and you won’t see the drive/volume anymore. removed is removed.

It may be easier to understand and manage that device if one were to use gparted instead of disks
