thanks and best regards

hi nejad ;
you cannot extend / filesystem by simple lvextend and extendfs commands.
you need to find which files filling /.
it is possible to share also
du -sk /*

Hi Nijad,

/u02/CA_CD +/- 900mb --> looks like you copied an installation cd into the root filesystem.

either move this to an other filesystem or create a filesystem for this data.

hi
i can't mouve this data or create new filesystem for this data.
how to solve this problem without moving any data.
thanks and best regards

[Robert-Jan Goossens]

You can´t solve it without moving the data.

Just a tought.

You have plenty of space in /opt.

# mv /u02 /opt
# ln -s /opt/u02 /u02

Now you have a link in / to the software in /opt/u02.

Hi
And what in regard to this message in file attached
thanks

[Robert-Jan Goossens]

/dev/vg00/lvol3 -- / filesystem has to be contiguous.

You can only extend /root filesystem if you use an Ignite backup tape/server and restore that image with the advanced option to a larger root filesystem.

[Srimalik]

Hi, Nejad

As you have free space in the vg , what you can do is:

1. Create a new lv with filesystem on it
2. move your data("/u02") to /opt (or smwhere else)

3. Mount the new lv on /u02

4. mv the data from saved location to /u02

Thanks
Sri

[Mousa55]

Hi
i am move the data and now i have 86% free space
but the error message of lvextend is still.
how to solve this problem
thanks

[Raj D.]

Hi Nejad,

I undestand that you are trying to extend vg00/lvol3 , as lvol3 is the root filesystem, you cannot extend it directly, you need to have special steps for that.
1. Boot from ignite-ux media, and extend recover.
2. reinstall and restore back.

Hope this helps,
Raj.

[F Verschuren]

the problems seems to be solved, next time porperly the new filesystem wil be full and that one can be extended.

to be sure there are no more other potential problems, can you post a new:
du -kx / | sort -rn | head -30

[Mousa55]

Hi
i have now space in the / file Because i move the more data from it.

# du -kx / | sort -rn | head -30
