Happy New Year!

there is a problem with my sdcard under Android 7.1.2 (Custom Rom) (root=true, adb=possible). The vFat Partition can be used, but the rest is not mounted and can not be used.

mmcblk1p1 vfat 183 GB Status : OK

mmcblk1p2 ext4 16 MB android meta Status: not mounted

mmcblk1p3 ext4 64 GB Status: not mounted (primary) (want to use that partition as adoptable Partition for extra internal memory)

mmcblk1p4 ext4 2 GB Status: not mounted (primary) (want to use that partition as SWAP Partition for extra RAM)

Trying to mount the Partition3 (64 GB) gives the error

mount: mounting /dev/block/mmcblk1p3 on /data/sdwyt2 failed: Invalid argument

Other similar error messages may also occur. Any help welcome !

Found the answer to my question myself here:

Solution: On devices running Android 7.0-8.1, file-based encryption (FBE) can't be used together with adoptable storage.
