I need to ask this question again in the hopes that something will come
of it. In the process of going through an update (I finally got that
sorted out) all of my partitions were renamed. Here they are:
Filesystem 1K-blocks Used Avail Capacity
Mounted on
/dev/label/rootfs0 507630 326734 140286 70%
/
devfs 1 1 0
100% /dev
/dev/label/var0 1012974 170386 761552 18%
/var
/dev/label/usr0 33292236 9358560 21270298 31%
/usr
linprocfs 4 4 0
100% /usr/compat/linux/proc
/dev/md0 789518 16 726342 0%
/tmp
As you can see, root, which was once /dev/ad0s1a, is now
/dev/label/rootfs0, and /var, which was once /dev/ad0s1d, is now
/dev/label/var0. Along with these changes the /etc/fstab was
automatically modified to allow the boot process to take place. Can
someone give me a heads up as to what is going on here.
Seems that you - or something - did make the switch from
device names to labels. Maybe your kernel now includes
GEOM functionality for work with labels? But I don't know
of a process that changes /etc/fstab automatically...
You can still use the device names for the /etc/fstab
entries, you just need to make sure that you select
the correct names (as you described above). Then there
should be no problem as labels are optional.
Honestly, I certainly didn't make the change from device names to labels. I
wouldn't know how to do that, although I gather from what you've said that
the kernel config file contains that information. I'm not sure, however,
what you mean when you say that I can still use the device names, as the
system will not boot unless fstab has in it the entries shown above.
FreeBSD is wonderful, don't get me wrong,
but it is not magical. Partitions don't just
accrue labels and /etc/fstab doesn't edit
itself.
Are you running PCBSD?
LOL! No, I'm running FreeBSD 8.1. I know that this all sounds too odd,
but I swear that I never messed with renaming the partitions with
labels. If you check back a few days you will see that I was having
trouble with an update, and that's where all of this happened.
Anyway, if you want to go back to device names
in the /dev/ad0s1[a-g] scheme you can extract
the correct names with:
geom label list
(you might want to pipe it into a pager)
then edit your /etc/fstab accordingly and
reboot.
Although, why bother really? The label names
may come in handy if you have to move the hdd
to another machine to extract the information,
or for various other reasons.
To tell the truth, I'm content to leave things as they are, but
unfortunately one of the side effects of all this is that I can't figure
out how create and entry in the fstab which will again allow me to mount
my other hard drive. The former fstab entry for that was:
/dev/ad1s1 /c ntfs rw 1 0
But now with labels active I really don't know how to proceed.
