If your mirrors are fine (gmirror status says COMPLETE) and filesystems on them are fine too, I think you can just disable gptid, diskid and ufsid since you're not using them. Add to your /boot/loader.conf these lines: kern.geom.label.disk_ident.enable=0 kern.geom.label.gptid.enable=0 kern.geom.label.ufsid.enable=0 About labels and geom: man glabel . Bye, f.
