RPM problems with Fedora 11 on Sheevaplug

[Eric Moody]

Hello everybody,
I have a SheevaPlug that I have loaded Fedora 11 onto.
When I use a USB memory key as my storage device RPM works great.
However I would like to run the system from the MTD.
I have create a jffs file system and flashed it onto the MTD. However
RPM just flat out refuses to works. I keep getting errors accessing
the Packages database. I have tried rebuilding that the database, and
even creating new databases from scratch. Below is the output I
receive.

-bash-4.0# rpm -qa  -vvv

I am thinking it has something to with the JFFS2 filesystem. Running
my USB memory key with ext3 works just file. I used the same tarball
to generate both filesystems.
This is the command I used to generate the JFFS2 filesystem.
mkfs.jffs2 -l -e 0x20000 --pad -r /home/rootfs-f11 -o fedora.jffs2


Thanks,
Eric

Two tips about RPM, don't know if they're exactly your problem but you 
can't operate without knowing the first one anyway.

If you see db problems, first move is

# rm -f /var/lib/rpm/__*

If you didn't shutdown cleanly, these "sticky database temp files" can 
be corrupted and tried to get use next time.  If they're deleted, 
they'll be regenerated silently.

Second one is another way to see "corruption" of those temp files is if 
you had been doing rpm --root= operations on your host on the image, I 
saw that the __ files can get marked with your host arch.  The device 
can see that in there and choke as well.  So, after host --root= 
operations on the rpmdb on SD card or whatever, I routinely delete the 
/var/lib/rpm/__* files too.

I don't particularly recognize the mmap: Invalid argument so maybe it's 
something completely different, but I noticed you don't show you tried 
the __ file deletion.

IIRC, JFFS2 has some issues with supporting writeable mmaps, and 
you need to inform rpm of this. 

Try including the following line in your 
$INSTALL_ROOT/etc/rpm/macros.rpmdb

%__dbi_cdb create private nommap
