I am setting up a new test server with Reiser4 and I have noticed an
error in 'dmesg' when mounting my Reiser4 partition on boot. This is
the error:

"reiser4[mount(1956)]: _init_read_super
(fs/reiser4/init_super.c:198)[nikita-2608]:
WARNING: Wrong master super block magic."

This message only shows up on boot...if I unmount the partition then
mount it again I do not get that error. I ran a 'fsck' on the
partition and everything looked OK...output is at end of message. I
have re-run 'mkfs.reiser4' on the partition but this did not stop the
'warning' message on boot.

I am running Gentoo Linux with gentoo-dev-sources 2.6.8 with
reiser4progs-1.0.1. The Reiser4 partition is a 200GB partition on a
software raid mirror.

Thanks for any help on this,
Dave

Fscking the /dev/md2 block device.
Will check the consistency of the Reiser4 SuperBlock.
Will check the consistency of the Reiser4 FileSystem.
