Adb remount W failed

Hi All,
After I flash the image of aosp 9.0, I compiled and then execute adb remount , the following error is prompted:

W failed to remount partition dev:/dev/block/platform/soc/ff3b0000.ufs/by-name/system
mnt:/system: Invalid argument/system/bin/remount exited with status 10
remount failed

Do you have any suggestions?

Has anyone ever met it?

adb shell mount -o rw,remount /dev/block/platform/soc/ff3b0000.ufs/by-name/system

However, you probably shouldn’t muck around in the system partition much. The idea behind the system partition is now such that it shouldn’t actually differ between devices, even radically different devices. Vendor specific modifications are to be contained within the vendor partition.
