List members=3B http://www.freebsd.org/doc/en/books/handbook/geom-glabel.html Starting with FreeBSD 7.2=2C the glabel(8) class supports a new label type for UFS file systems=2C based on the unique file system id=2C ufsid. Is the above clause applicable in this case ? instead of using tunefs -L= =20 can we use# glabel status ? and can use the ufsid labels of /dev/ufsid/ and edit /etc/fstab ent= ries for the partitions? > From: valentin.bud@gmail.com > Date: Wed=2C 10 Jun 2009 09:12:47 +0300 > To: freebsd-questions@freebsd.org > Subject: glabel(8) a gmirror(8) doesn't work >=20 > Hello community=2C >=20 > Yesterday I have installed FBSD 7.2-RELEASE.
