Hi,Christian
Thanks for your help. Now, the file system can be mounted. However, there's still errors in my test.That is File_system-session creation failed. Here's the output message:
[init -> part_blk] Partition 1: LBA 10240 (7733248 blocks) type: 83
[init] child "part_blk" announces service "Block"
[init -> part_blk] session opened at partition 1 for 'rump_fs -> '

[init -> rump_fs] asserting rump kernel 14253 KB of RAM
[init -> rump_fs] rump: /genode: file system not clean; please fsck(8)
[init] child "rump_fs" announces service "File_system"
[init -> test-file] Error: File_system-session creation failed (ram_quota=163840, cap_quota=12, tx_buf_size=131072, label="", root="", writeable=1)
[init -> test-file] Error: failed to create <fs> VFS node

[init -> test-file] Error: plugin()->open("file.txt") failed

I don't know whether it's because there's some mistake in my configuration. Can you give me some hint? The run scripts is just like that I showed you before. And here's test file:
