Hi Admins,
I have created a strip set using three 18GB DS-RZ1ED-VW drives in our AS4100
box running Tru64 v4.0G patch 1.
The devices are rz19, rz20 & rz21. Then I created another striped set with
identical drives on the next shelf using devices rz27 rz28 & rz29. These all
belong to disk group oracledg. In the file system, this has been named
u03_oracle and is mounted as /u03.
Here are the settings for this disk group which I have named oracledg:
# volprint -g oracledg
TYPE NAME ASSOC KSTATE LENGTH COMMENT
dg oracledg oracledg - -
dm oracled01 rz19 - 35564040

plex oracle-02 oracle ENABLED 53128704
vol oracle fsgen ENABLED 53128704
These settings in fstab look correct to me (the last entry, /u03, is the
object of concern):
# cat fstab
root_domain#root / advfs rw 0 0
/proc /proc procfs rw 0 0
usr_domain#usr /usr advfs rw 0 0

u02root#u02root /u02 advfs rw 0 0
u03_oracle#u03 /u03 advfs rw 0 0
The goal was to have one 54GB array on the main system shelf and mirror it
to another identical set on the next shelf above.
All seemed to go as planned. When I created the first strip set, all three
disk activity lights showed activity. The same for the second strip set. And
when I mirrored the first to the second, all six lights were active for
several hours.
However, I am only able to see 26GB using df -k (it is the last entry):

Does anyone have an idea as to why /u03 is only showing half the size it
should be?
