Using a real harddisk

[Wolfgang Schmidt]

Hi,

I have still the old problem with using the blk_cache and rump_fs (latest 
release 14.05).
I tried to do the following:
- have a larger blockcache which is used by part_blk
- have multiple partitions and rump_fs (which is working) which nearly no 
cache and which shoudl threfore use the blockcache (which is not working)

I shortened the configuration below to the relevant(hopefully) part with 
only one partinion.

If I use the configuration 1 i can read / write a file on the system.
With configuration 2 the system seems to stop without any further 
information. (same result with config 3)
    [init -> rump_fs] upgrading quota donation for SIGNAL session
    [init -> rump_fs] Backend::Backend(): Backend blk_size 512
    [init -> rump_fs] rump: /genode: file system not clean; please fsck(8)
-execution seems to stop here-

The "file system not clean" seems not to be the relevant part, it is also 
shown if the program  steps through.
(with config 1
    [init -> rump_fs] upgrading quota donation for SIGNAL session
    Quota exceeded! amount=20480, size=4096, consumed=20480
    [init -> rump_fs] upgrading quota donation for SIGNAL session
    [init -> rump_fs] Backend::Backend(): Backend blk_size 512
    [init -> rump_fs] rump: /genode: file system not clean; please fsck(8)
    Quota exceeded! amount=24576, size=4096, consumed=24576
    [init -> rump_fs] upgrading quota donation for SIGNAL session
    Quota exceeded! amount=94208, size=4096, consumed=94208
    [init -> rump_fs] upgrading quota donation for Env::RM (8192 bytes)
    Quota exceeded! amount=28672, size=4096, consumed=28672
    [init -> rump_fs] upgrading quota donation for SIGNAL session
... and so on until file is read/written
)

What am i possibly doing wrong?

Best regards,
Wolfgang
