Please migrate away from this immediately, your data is at risk. http://wiki.freebsd.org/JeremyChadwick/ATA_issues_and_troubleshooting The problem you're experiencing is documented there. There is no solution, as far as I know. The problems still exist on RELENG_7 also. I recommend you back up (off-load) all of your data onto a disk or system somewhere else, and use gmirror(8) instead. Please, stay away from Intel MatrixRAID on FreeBSD. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
