Yes, exactly as noted in the Handbook's example.
Still ufsid labels are not exactly 'memorable'

Well yes you are right. The point of labeling the partitions was/is to
make the names more easier to remember IMO. Remembering a
string (the ufsid) is not quite my specialty. Anyway thanks for the heads
up.

RE: glabel(8) a gmirror(8) doesn't work

[dhaneshk k]

List members;

http://www.freebsd.org/doc/en/books/handbook/geom-glabel.html

Starting with FreeBSD 7.2, the glabel(8) class
supports a new label type for UFS file
systems, based on the unique file system id, ufsid.

Is the above clause  applicable in this case ? instead of using  tunefs  -L 

can we use#  glabel status  ?

and can use the ufsid labels   of  /dev/ufsid/and  edit  /etc/fstab entries 
 for the partitions?

Yes it worked. Thank you very much. The odd thing is that I once
tried to label it after mounting / and rw and afterward changed it to ro
with the help of mount and it did not work.

a great day,

You should be able to. Just reboot into single user mode and *do not*
enter any mount commands.  The / partition is mounted read only in this
case, and tunefs -L will succeed.

Thanks this time it worked. I am almost sure (99%) I've tried that already
yesterday but the 1% wins.

try
to label it.

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".


replace mount -a with mount /

you can't write directly to partition which is mounted mounted
