Hi, I'm attempting to setup a storage server with mirroring and journalled filesystems using 1TB drives. Initially I did the following: sysctl kern.geom.debugflags=17 dd if=/dev/zero of=/dev/ad8 bs=1k count=1 dd if=/dev/zero of=/dev/ad10 bs=1k count=1 gmirror label -vb round-robin gm0 /dev/ad8 gmirror load gjournal label /dev/mirror/gm0 gjournal load newfs -O 2 -J /dev/mirror/gm0.journal mount /dev/mirror/gm0.journal /mnt/mirror2 gmirror insert gm0 /dev/ad10 ,but read in the archives there are potential issues with the labeling. Does anyone have any suggestions (or references to documentation) describing how this could be done? Are the GEOM parts for doing this sufficiently mature to consider this safe? This did seem to be working, but when I did a dump I got kernel panics like others who have posted recently. Thanks, J. Mingrone
