"panic: ffs_blkfree freeing free block" X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 02 Apr 2009 20:27:38 -0000 About every 5-10 minutes, my freshly installed freeBSD 7.1 stable box hangs and begains a kernal dump. I get the following error message: dev = twed0s1d, block = 1, fs = /archive panic: ffs_blkfree freeing free block cpuid = 1 Uptime = 11m23s Physical memory: 1011 MB Dumping 67 MB: 52 36 20 4 Dump complete /archive has no files in it as it is an empty filesystem. In fact, it's a seperate spindle from the OS disk. fsck does not resolve the problem: #> umount /archive #> fsck -t zfs /dev/twed0s1d and I've verified that the disks involved don't have bad blocks. Since the machine becomes non-responsive after the dump, I can't access logs or anything to see what happened. Machine is using ASUS P2B-D mainboard (dual 500Mhz PIII Intel), with a 3ware 7000-2 raid card. The 3ware has 2 Maxtor 200GB drives in a RAID-1; these would normally be mounted as /archive. The volume is empty (no files). Google shows lot's of people having similar problems with zfs, but no solutions that I have found yet. Anyone have any ideas? Thanks, John H.
