Re: i need to increase the space in / and /var ...

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

Re: i need to increase the space in / and /var ...

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".

Re: i need to increase the space in / and /var ...

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.

Check this thread for more information,

Re: i need to increase the space in / and /var ...

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

Re: i need to increase the space in / and /var ...

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
