If your vgdisplay doesn't show the volume groups you can restore it from .mapfile.

The .mapfile reside in /etc/lvmconf directory

Hi Nejad

Sorry I forgot the mount -a command after umount operation.

Can you try mount -a and submit bdf

Well I am afraid to say you are confusing things terribly here.
You started talking about vgoracel, then went to vg01, now you are complainign about vg00/lvol2 and lvol3?


>sorry, the my data in vg00 under / "/dev/vg00/lvol3 /u01" but the /u01 is empty not Contain any data.

Well that is (I assume) the mount point for /dev/vgoracle/lvol1 adn if it is not activated, it will not mount as per my origional response, and therefore the directory will be empty!!!

>and i am find a strange thing the lvol2 from vg00 is not appeared by bdf command.
but by using the SAM i can see but the filesys state is swap/dump ???
Well this is the primary swap space ane NEVER has a file system, so will not show up in bdf output!

# vgchange -a y /dev/vg00/lvol3
vgchange: Volume group "/dev/vg00/lvol3" does not exist in the "/etc/lvmtab" file.
Why are you trying to vgchange a logical volume? This is not possible!


It seems you have also been able to activate vgoracle, try to do :
mount -a
bdf

See if this now mounts your /u01

I suggest you think more carefully about what you are trying to look for here, as you are going around in circles.

Hi Nejad

You confused commands :) don't worry.

Please apply following lines and submit outputs

#umount /dev/vg02/lvol1
#mount -a
#bdf

and also submit

#cat /etc/fstab
