Out of Disk Space (overlayfs seems incorrect)

Here we go!
This is the partition table at first boot

root@volumio:/home/volumio# parted /dev/mmcblk0 print
Model: SD USDU1 (sd/mmc)
Disk /dev/mmcblk0: 15.8GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:

Number  Start   End     Size    Type     File system  Flags
 1      512B    64.0MB  64.0MB  primary  fat32        boot, lba
 2      64.0MB  2500MB  2436MB  primary  ext4
 3      2500MB  15.8GB  13.3GB  primary  ext4

So the partition has been resized, but

Filesystem      Size  Used Avail Use% Mounted on
/dev/mmcblk0p2  2.2G  588M  1.5G  29% /imgpart
/dev/loop0      294M  294M     0 100% /static
overlay         262M   14M  228M   6% /

so the resize2fs has not been run.
I can’t directly resize mmcblock0p3, it is failing

root@volumio:/# resize2fs /dev/mmcblk0p3
resize2fs 1.42.12 (29-Aug-2014)
resize2fs: Device or resource busy while trying to open /dev/mmcblk0p3
Couldn't find valid filesystem superblock.

but I can mount it and then resize it (weird, I know)

root@volumio:/# mount /dev/mmcblk0p3 /tmp
root@volumio:/# ls /tmp/
dyn  lost+found  union  work
root@volumio:/# resize2fs /dev/mmcblk0p3
resize2fs 1.42.12 (29-Aug-2014)
Filesystem at /dev/mmcblk0p3 is mounted on /tmp; on-line resizing required
old_desc_blocks = 1, new_desc_blocks = 2
The filesystem on /dev/mmcblk0p3 is now 3256016 (4k) blocks long.
root@volumio:/# umount /tmp
root@volumio:/# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/mmcblk0p2  2.2G  588M  1.5G  29% /imgpart
/dev/loop0      294M  294M     0 100% /static
overlay          13G  143M   12G   2% /

Sorted :wink:
I don’t have time to investigate why the partition is resized, but the FS is not, sorry
