There are tools available in ports (sorry, I forgotten how they are called) that can access the drives internal fault statistics. Maybe your drive has an error and locks up all of a sudden. Since a journal leads to more disk activity it would be normal for a hardware related error to happen more early. I might be pretty wrong here, but the T60 has an internal movement sensor that needs some software to turn of the hard drive. Maybe your laptop has a sensor too, but the logic behind it is implemented in hardware? > Something else i also noticed is that, after every crash, I couldn't just > reboot and use my computer just fine, as I would have expected - maybe I'm > wrong here. > I had to go into single user mode, and run a fsck /dev/ad0s1f.journal . this > takes about 4 minutes.

You might want to search the list archives (especially freebsd-current) to get some details on ZFS and possible problems regarding it. There seems to be an issue with ZFS and Samba and/or NFS. A nice summary is in the archives: http://lists.freebsd.org/pipermail/freebsd-current/2007-August/076411.html I don't know what the current status is, thou. And I never suffered from this error. In fact I'm using a raidz with 4x400GB HDDs. One use is as a storage for satellite video streams, so there are pretty big files written to it using NFS. One thing I really like about ZFS is that it gets rid of the old partition/slice paradigm. You'll never be angry with yourself again because you selected the wrong size for your partition/slices. > > thanks for any ideas, comments, pointers :) > > B HTH Christian -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHMh7mND6QF/amlKsRArRMAJ99Siy5hoACgV+DMUF68dtwpkfPDACeLRPq Lsn2Uk+OBEhh7wgvwJE+FmA= =ZaeE -----END PGP SIGNATURE----- _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
