systemd creates .device for any partition it finds, but that doesn't
mean the partition is mounted.<br>
<br>
You should trust "mount" in this case. Your partition is not mounted
and I don't think this is a systemd problem. People on the yocto
side are probably more able to help<br>
<br>
now, that being said, I am not sure what "the kernel partition
table" is in this context. I assume parted is trying to refresh the
way the kernel sees the partitions on the eMMC and fails, which
would be a pure kernel problem.<br>
<br>
If you repartition your eMMC and then reboot on the sd-card, does
your kernel see the partitions correctly ?<br>
It kinda seems to me that everything is working fine here, and that
the message is a red herring...<br>

Hi list,
i'm new to systemd and are working with an embedded device with yocto.
In my embedded device i want to format and store my emmc device with the new firmware. When updating the firmware the device boots from SD card.
When updating the firmware i want to (re)partition my emmc storage device with parted and 3 ext4 partitions. None of the partitions is mounted, because the device boots from SD card.
When the emmc already contains a partition table parted complains that it can't update the kernel partition table after it was modified.
It seems these partitions are already mounted anywhere. partprobe doesn't help either.
But i don't mount them and when i check for mounted partitions by mount command, none of them is mounted. The only thing i see is that systemd has created device units for these partitions. In syslog i see that the ext4 partition is recognized (also in /sys/fs/ext4 available). I assume that the systemd device units block the update of the kernel partition table.
I need to modify, format and fill the partitions on the emmc without booting after the new partition table is written.
My question is: What/is systemd blocking the update of the kernel partition table and what can i do to prevent it?
Thanks in advance
Eberhard
