Why d?nt u use glabel?

hmm, I never considered it
but I guess it does not solve my problem because let's say da0 is the
provider and da0 might have still the label I gave it but the OS can not
see it since it is then aacd0 after changing the controller or am I
wrong?

Hmm...

Advisory: :-))
1.
Just try it. Dont believe me without thorough testing... :-)
E. g. with (a) mdconfig -a -u 0 -f testdevfile ; glabel label -v fook md0 ;
mdconfig -d -u 0 ; mdconfig -a -u 69 -f testdevfile ; ls /dev/label

2.
I think that is one advantage of glabel: It does not care for the device
name, but it just tastes the last sector of each device, as soon as it
shows up (e. g. after the reboot).



thank's Arne, I will give it a try on a test machine and give you a feedback
on it

Also this has nothing to do with FreeBSD performance so followups
should be elsewhere.
