Those servers are running a software raid-1 using geom_gmirror. Today, when I rebooted them twice with 'reboot' command, raid-1 running on both servers got degraded to 0% + filesystem check resulted in 4-5 lost non-critical files. Later I found out that 'reboot' is not a recommended way to reboot a system, and I should use 'shutdown -r now'. Anyways, I'm thinking to use gjournal (in addition to gmirror) on both servers to avoid such situation in future. I'm already using gjournal on my desktop (with no gmirror) running FreeBSD 7.0-RELEASE-p1 (amd64), with no issues. So, I wanted to know if gjournal + gmirror combo is stable enough to be used on a servers. And, if I go for gjournal, since I've an existing filesystem, I've to create a separate gjournal slice, so is it okay to create that gjournal slice on a non-gmirror backed storage, hmm...?
