Hello, I'm attempting to set up a storage server with mirrored and journaled filesystems. 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 I read in the archives there are potential issues with the labelling. 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.
