MTD JFFS2 Problems

[Jeff Stevens <jsteve17@yahoo.com>]

I am trying to create a jffs2 filesystem, and it seems
to be very flakey.  I have tried creating a jffs2
filesystem using mkfs.jffs2 and then copy it directly
to /dev/mtd0, but when I try to mount it I get a bunch
of errors, and when it finally mounts, the filesystem
acts weird.  So now I am trying a different approach,
where I mount an erased mtdblock0 as jffs2 and then
untar a filesystem on the mounted device.  However,
when I do this it seems to crap out at various points
in the filesystem (I have tried it many times).  Here
is a screen dump:

[root@gtvme ~]# mount -t jffs2 /dev/mtdblock0
/mnt/root
[root@gtvme ~]# cd /mnt/root/
[root@gtvme root]# ls
./  ../
[root@gtvme root]# tar xf /gtvmefs.tar

[root@gtvme root]# Write clean marker to block at
0x00a20000 failed: -30
Write clean marker to block at 0x00820000 failed: -30


I'm not sure what I'm doing wrong.  I seem to be able
to copy things to flash just fine using dd, and
flashcp.  Please help!

Thanks,
   Jeff Stevens
