Target is busy #570

I often have this issue, toward the end of the compilation:

Disconnect block device
/dev/nbd0 disconnected
Shrinking qcow2 image
Image resized.
Convert qcow2 to raw image

Get PARTUUIDs from image
Boot: 7d4f58c4-01
Root: 7d4f58c4-02
Mount image
Setup PARTUUIDs
Set UUIDs to make it bootable
Umount image
umount: /var/lib/jenkins/workspace/5_ISO/work/WaziGate/tmpimage/boot: target is busy.

The script cannot umount the temporary image. However, I can do it manually with sudo umount /var/lib/jenkins/workspace/5_ISO/work/WaziGate/tmpimage/boot. Any idea?

Adding qcow2 image support seems to have caused too many issues, so since https://github.com/RPi-Distro/pi-gen/commit/68fee340f95eb630a706e2dbf75615c6be4e980b it is marked as experimental and is definitely not recommended.

So not using qcow2 will be more reliable? What will be the performance hit?

XECDesign commented 2 years ago

It will use a LOT more disk space.
