Hello all.
I just installed FreeBSD 9.0 RC2 and upgraded to 9.0 RC3.
I used the standard GPT disk layout at install.
Now i want to set labels for my disk, so that i can swap around disks a
little more easy.
So reading through the man page it told me to use gpart modify -i -l
The layout is as follows:
test# gpart status
Name Status Components
da0p1 OK da0
da0p2 OK da0
da0p3 OK da0
test# gpart list | grep label
label: (null)
label: (null)
label: (null)
Now i modified the gpart labels.
test# gpart modify -i1 -l bootpart da0
da0p1 modified
test# gpart modify -i2 -l rootpart da0
da0p2 modified
test# gpart modify -i3 -l swap da0
da0p3 modified
Ok all looks fine.
Now lets see if i can use my labels
test# cd /dev/gpt
/dev/gpt: No such file or directory.
Well it does not create my labels
I did check if the labels where there
test# gpart list | grep label
label: bootpart
label: rootpart
label: swap
So i rebooted the machine!
But after a reboot, still no /dev/gpt.
So why is it not creating my labels!
Am i missing a step?
Thanks for your time.
And before i forget, merry christmas to all, and a wonderful 2012.

I was going to say if you mount /dev/da0p? its /dev/gpt/label
disappears,
and since all the partition are mounted already [/dev/gpt/ is empty],
then
/dev/gpt is maybe also removed.......but /dev/gpt/bootpart is not
mounted
and should still show up.
When you ran the 'gpart' commands, did you set the sysctl geom debug
variable? [sysctl kern.geom.debugflags=17]
After the reboot, are the labels still there? [gpart list | grep label]

I placed some other disk in (for the zfs pool)
Now i have /dev/gpt/bootpart, but not the labels for swap and /
I did not use the sysctl value.
And yes the labels are stil in place.
test# cd /dev/gpt
test# ls -al
total 1
dr-xr-xr-x 2 root wheel 512 Dec 23 20:02 .
dr-xr-xr-x 10 root wheel 512 Dec 23 21:02 ..
crw-r----- 1 root operator 0, 123 Dec 23 20:02 bootpart
test# gpart list | grep label
label: bootpart
label: rootpart
label: swap
test#
I will try the debugflag option.
But it should not be nessacary i guess.
thanks

If you have already mounted a /dev/da0p?, its label is removed from
/dev/gpt - 'bootpart' is never mounted, that is why it's label remains.
you just have to change /etc/fstab to the /dev/gpt/labels and then they
will remain and get mounted - Or boot from a DVD, don't mount anything and
you'll see the labels.
ie:
If you mount '/dev/da0p2'as '/' then '/dev/gpt/rootpart' will no longer be
available, same goes for swap and everything else. If you mount
'dev/gpt/rootpart' as '/', the you'll have both '/dev/da0p2' and
'/dev/gpt/bootpart'

Thanks that solved it. !!
because i did not see them in /dev/gpt i did not change the /etc/fstab
file to the appropiate config.
I thought if they are not there, then i can not use them.
Wrong assumption !!!
I edited /etc/fstab to mount /dev/gpt/rootpart on / and /dev/gpt/swap on
swap, and the machine booted like it should.
Also the gpt entries are now there!
Thanks again!
Merry cristmas !!!
regards
Johan
