Hi

in freebsd this is called softupdates and can be enables using tunefs (see
the man page).

If not quite journaling as it does things slightly differently, but achieves
many of the same effects, like reduced fsck time on boot.

I've had some problems earlier this year due to FreeBSD-6.0 crashing
after a few hours of execution (perhaps it's mal-functioning hd's dma,

out! ^^). And so I thought of journaling file systems.

I think XFS is being ported to FreeBSD, but last news on the official
page (http://people.freebsd.org/~rodrigc/xfs/) dates from December
12th, 2005 (and it's still read-only). So...

Is there a journaling file system (rw ready) available? Which one?

Another question: how can I completly diable hd dma? -.-"

You can disable DMA with the atacontrol command: for example

atacontrol mode ad0 pio4

I have a Maxtor 40GB which won't work in DMA mode with FreeBSD, although
it seems fine with other OSes.  There is a hefty perfomance hit, of
course!


Did you tried with different ATA cable? I've solved this kind of issues every time by changing the cable or by lower-ing the settings for ATA, like instead of ATA133 to use ATA100, or ATA66.

#atacontrol list
#atacontrol mode ad0 ATA66

Try that, if it works, try ATA100.
Your hard drive, motherboard and your cable, all must be ATA100 to support that speed.
