Hi,

When trying to add a new partition to an already existing disk slice on =
FreeBSD 5.4, are these  the proper procedures to follow:

lets say we have:

/dev/ad4s1a    507630   56104   410916    12%    /
devfs               1       1        0   100%    /dev
/dev/ad4s1d    507630      12   467008     0%    /tmp
/dev/ad4s1e  10154158 1833920  7507906    20%    /usr
/dev/ad4s1f   6090094   40804  5562084     1%    /var

There is some 20GB unused space on the drive and I want to use that for =
/backup, so I did:

1) sysctl kern.geom.debugflags=3D16

2) sysinstall -> Confgiure -> Disk Label -> ad4

3) I've mounted each ad4 to its proper place using 'M'=20

4) then I created the partition /backup using 'C' from the unused space =
which wass assigned /dev/ad4sa1g

5) then used 'W' to write the partitions, it gave couple of errors about =
busy devices..etc

6) reset sysctl:  sysctl kern.geom.debugflags=3D0

7) rebooted the machine and it came back fine

8) edit /etc/fstab and add=20
/dev/ad4s1g		/backup	ufs	rw	2	2

9) reboot the machine and it fails to come back on

am I missing something ?

Thanks,

Tamouh Hakmi
