Help,

I thought I created a 70G vg09, what happened ?

Note that you mounted /u09 on /dev/vg09 rather than something like /dev/vg09/lvol1. The first thing I would do is ls -l /dev/vg09; let's see what the underlying device node looks like. Also, what is the output of vgdisplay -v /dev/vg09?

Shalom,

Did you check the return code from the newfs command? Was it zero.

I'm guessing a mistake was made somewhere along the line. Maybe keyboard history will reveal it.

Clay has hit the nail on the head, I think.

You have somehow mounted /dev/vg09 to /u09.
You should have mounted /dev/vg09/lvol1 to /u09.

Try this:

# cd /
# umount /u09
# bdf -l

Verify that there is no entry for /dev/vg09 or /u09. Assuming there isn't, proceed.....

# mount /dev/vg09/lvol1 /u09
# bdf -l

See what the entry for /u09 looks like now. It should be the size you created lvol1.

Thanks guys,

I mounted it wrong....
