Problem with graid3 and gjournal

[Rafael Henrique Faria]

I'm using a GJournal on top of GRAID3 on top of GPart.

What happens:

If I go to my gjournal mount point e put:

dd if=/dev/zero of=file bs=1k count=10

The system freeze. No more response in the corrent ssh session, the
system don't respond to new ssh connection, and the console got
freezed too.

So, I tried with:

dd if=/dev/random of=file bs=1k count=10

The same thing.

I went to an other machine, created the file with:

dd if=/dev/zero bs=1k count=10 | bzip2 | dd of=file.bz2

The file is created OK.

I send the file to my machine using gjournal, and:

bzcat file.bz2 | dd of=file

The system got freezed again.

In the same server, I have an other partition with gmirror, and
gjournal on top of it.

The file was created OK. Then I tried to copy the file from the
gmirror+gjournal partition to the graid3+gjournal partition, and the
system got freezed again.

Then I belieave that there is a problem with graid3+gjournal.

If I create filed in the graid3+gjournal with the VI, or send any
other file (ie. /etc/rc.conf) to this partition, is OK. No freeze.
Only when I try to create a file with dd.

Where is the problem, with GRAID3, or with GJournal ?

I'll try to remove the GJournal from this partition. But anyone knows
somethig about it?

I think that GJournal can't be on top of a GRaid3. But GJournal on top
of GMirror is working very good.

Thank's for any help.
