Can't figure out where MicroSD space is

[kendew]

In trying to troubleshoot an unusable PPB I've just received, I bought a 64G MicroSD card to boot the Fedora 32 Xfce image.  I'm partial to Fedora, and wanted something different from the Manjaro or KDE that is pre-installed for testing purposes.   With dd the install was easy and Fedora booted like a charm.  I've added only apps I needed, like Firefox and Geany to keep it simple.  But even so, the operating system seems to think I have no space left on the MicroSD.

We have lsblk showing the MicroSD disk, mmcblk2, essentially full:

Code:

$ lsblk
NAME         MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
mmcblk2      179:0    0  58.2G  0 disk
├─mmcblk2p1  179:1    0 213.6M  0 part
└─mmcblk2p2  179:2    0    58G  0 part
mmcblk2boot0 179:32   0     4M  1 disk
mmcblk2boot1 179:64   0     4M  1 disk
mmcblk1      179:96   0  59.5G  0 disk
├─mmcblk1p1  179:97   0 213.6M  0 part /boot
└─mmcblk1p2  179:98   0  10.7G  0 part

With df we get a similar story:

Code:

df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        1.9G     0  1.9G   0% /dev
tmpfs           1.9G   99M  1.8G   6% /dev/shm
tmpfs           1.9G  9.5M  1.9G   1% /run
/dev/mmcblk1p2   11G  9.8G  201M  99% /
tmpfs           1.9G   48K  1.9G   1% /tmp
/dev/mmcblk1p1  214M  134M   81M  63% /boot
tmpfs           380M   24K  380M   1% /run/user/1000

But in fact, du gives:

Code:

$ sudo du -sh *
0    bin
134M    boot
0    dev
28M    etc
2.6G    home
0    lib
0    lib64
4.0K    lost+found
4.0K    media
4.0K    mnt
4.0K    opt
du: cannot access 'proc/4494': No such file or directory
du: cannot access 'proc/4497/task/4497/fd/3': No such file or directory
du: cannot access 'proc/4497/task/4497/fdinfo/3': No such file or directory
du: cannot access 'proc/4497/fd/3': No such file or directory
du: cannot access 'proc/4497/fdinfo/3': No such file or directory
0    proc
3.3G    root
9.5M    run
0    sbin
4.0K    srv
0    sys
40K    tmp
3.5G    usr
442M    var

Your counting may be better than mine, but that doesn't look like much more than 10G.  At the moment, the OS complains of lack of space, which limits my ability to do much.  What am I missing here?
Any ideas much appreciated.
