I have installed on a mirror created with gmirror(8). All I have modified on this system is that I have updated the sources, rebuild the world and kernel and of course install. I have named the mirror system0 and all worked well. Now the problem is that i want to glabel the partitions on the mirror so i have followed the following procedure: 1. reboot to single user 2. mount -a 3. tunefs -L var /dev/mirror/system0s1d This commands exits with "Failed to write superblock". After reading the man of gmirrror(8) and glabel(8) i have noticed that both of them store metadata on the last sector of the provider. From this results that what I want to do is not possible, at least my logic tells me that. Since gmirror wrote metadata to the last sector of the provider, glabel tries to rewrite it and the system stops the process to protect the filesystem. But then again for gmirror the providers are the two hdd i use for mirroring and for glabel the provider is the mirror itself. That's again what my logic tells me. So i think there is some kind of separation between the two modules and things should work. I have searched a bit but couldn't find any relevant info on labeling a mirror. I just want to know if this is possible and if it's not I'd like to understand why. Labeling a partition is not a must-have but it's sure nice :). thanks, v -- network warrior since 2005
