Hi

have a look at /var/adm/crash to see if there are any dume files.

Do you have OnlineJFS installed ? if you do then it is easy.
lvextend -L 8192 /dev/vg00/lvol8
/usr/lbin/fs/vxfs/fsadm -b 8192M /var

this will increase /var to 8G of course, if you still have enough space left.

I have not done this for / before but I think it is the same. Correct me if I am wrong.

thanks

Hi Sekar,

Do not worry about / FS. I see no issues. Used percent is 8%.

/var is of some concern, the space could be retained by trimming log files. Go to SAM for trimming some log files. If you could not retain enough space u can consider extending it.

Though the link provided below is for extending /tmp FS, it is valid for /var aswell. The link contains solution for both cases, based on having online JFS or not. If you do not have online JFS, follow my instuctions in the below pasted link. Just one info, in my post ..use "bootwait" instead of "sysinit".

Hi Sekar,

To increase / space, you need to re-ignite the system and do it again. There is no way of increasing / size without an Ignite.

Extending lvol8 which your /var is ok using online JFS explained above, but you cant really do that for lvol3 (/).
As lvol3 needs to be contiguous filesystem with Bad block turned off.

I am not sure why you are getting error for / as i can see almost 900MB free. Best would be to extend /var and try the installation and if it still complains there are 2 ways to extend /

1. Using a make_recovery and restoring the system back using that.
2. Move lvol4 and lvol5 to another place and free up the extents after lvol3 and then extend your lvol3 using online JFS

thanks guys for ur support..
i will be working on it on monday..
i will update u on monday morning..

thanks,
sekar

[inventsekar_1]

thanks u so much guys...
i did lvextend -L .... /dev/vg00/lvol8
and the /etc/inittab file entry.

my knowledge also extended with my logical volume.

one more question:
senthil:
u told that i can remove that line after rebooting.
if so, what does it mean..?
how system knows the extended size when rebooting next time?..

Hi,

Yes, after your extend your filesystem, is not necessary run this command ever boot.

If you use hp-ux 11.11
There is only once way to extend / file system-
> you must use ignite

With /var file system
If online JFS is available on your system, you can do as:

# lvextend -L 8192 /dev/vg00/lvol8
#/usr/lbin/fs/vxfs/fsadm -b 8192M /var
Otherwise:
#init 1
#umount /var
#lvextend -L 8192 /dev/vg00/lvol8
#extendfs -F vxfs /dev/vg00/lvol8
#init 3

Hi sekar,
it is not possible to increase / filesystem with the LVM commands. You can only increase it with ignite.
Take ignite of your system
make_tape_recovery -Av

break in boot
search
boot p? (your tape drive)
No to interact with IPL

Press "Return" for the specified mode.
Yes to user interface

User interface will be appeared. Choose Install HP-UX.
Choose filesystems tab.
Then increase / filesystem size from here.

Best regards,
Onur

Shalom Sekar,


To increase root,

Take a make_tape_recovery backup of vg00.

Boot the system off this tape and press a key when prompted to get into the Ignite install interface.

Make root and var for that matter bigger.

Before you bother though, make sure you are not storing any real files in root. its really only there to provide path to other filesystems.

I keep root on HP-UX systems at 1 GB just to make mistakes less annoying. I rarely if ever use more than 200 MB.

thank u all...
i incresed the space in /var
and i learnt from u that using tap only its possible to increse the space in /

thanks once again..

I read this thread with interest, as I need to extend /usr and /var on my hpux 11.00 system. It looks like these instructions will work great for /var, but because lvextend and extendfs live on /usr, I'm imagining it won't work for that filesystem. What should I do?

[Torsten.]

"What sould I do?"

Open your own thread for your own question!

This is usual in every forum.

BTW, you should boot to LVM maintenance mode and do the modification.

[inventsekar_1]

"It looks like these instructions will work great for /var, but because lvextend and extendfs live on /usr, I'm imagining it won't work for that filesystem"

the second "/usr" is "/var". typo error isnt?

no. not like that. where commands live doesnt matter.

anyhow no problem to ask a question inside another question. it is the question auther's responsibility to assign or not assign points.

[James R. Ferguson]

Hi Judy:

Do:

# whereis lvextend
# whereis extendfs

...and you will see that a statically-linked binary for each lives in '/sbin' which will thus be available in single-user mode.

Regards!

Thank you for your responses. I'll give it a go. Sorry for being a newbie :-)
