Really, I wonder why geom_label pickup only LAST parition. Why it doesn't create labels for OTHER filesystems when geom_mirror is not loaded?! Problem is only with ONE partition, that is what surprises me.

Use hardcoded providers names And have problems with AHCI/ATA switches (main/rescue systems)... Really, it looks like global GEOM problem -- that user must choose between "hardcoded" providers and non-deterministic tasting. Maybe, adding user-configurable "class ranks" is good idea. So, it will be possible to tell system, that geom_part taste first, geom_mirror second and all other after that in any order, for example. Or vice-versa, in case when geom_mirror is used on whole disk. -- // Black Lion AKA Lev Serebryakov <[email protected]> _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-geom To unsubscribe, send any mail to "[email protected]"
