How do ypu increase the space in the "/" filesystem

How do ypu increase the space in the "/" filesystem??

[Leif Halvarsson_2]

Hi,
Not very easy. The root volume need contigous allocation so increasing space is in most cases not possible. You need to backup/recover the system with (for example) Ignite.

Hi David,

How large is your root filesystem ?

Is it possible to move "data" to another filesystem or to remove unwanted data ?

# find / -size +10000 -xdev -exec ls -l {} \;

and look for large unwanted files.

The most save way is to use a ignite tape (make_tape_recovery) and boot from tape with the advanced options, change the size of /stand from the installation menu.

Hope this helps,
Robert-Jan.

Root file system cannot be extended as compared to other file systems as the space is to be contigous.

you can build a IGnite tape for the system.
Using that ignite tape you alter the space of the root file system.

you can check ignite at

Also check the man pages of make_tape_recovery.

Revert on further help

Just do a search on the forums for the subject "extend root file system" there are lot of posted questions on this subject.

[Marco Santerre]

Your best bet is to use an Ignite tape and redistribute the space on your root volume to allow / to have more space.

Here is a thread very similar to yours

Hi,
Just to complete my previous reply.

It may be possible to extend the root volume if:
- There is space left in the root volume group.
- The / volume is the last volume in the root volume group.
- You have Online JFS installed.

I extend root as follows.

make a make_tape_recovery tape

Boot off make_tape_recovery tape
(Interupt at 10 second prompt, sea bo p# replace # with sequential device do not interact)

Interupt Ignite at the Ignite 10 second interacttion prompt.

Now, assuming there is any space left on the root drive, you can make adustments.

Hi there,

First thing fist is you need to get a free space first on your vg00, check the free PE or add another disk on vg00.

Another thing that you need to know that '/' and '/stand' filesystem is a contigous filesystem, so you need to allocate the contigous free space to extend these filesystem. This way is unsupported way by HP 8-).

And here is the supported way : re-install the whole system (hardway) OR using Ignite/UX features (easyway).

I choose the easy one by creating a bootable backup tape with make_tape_recovery command, boot the system from that tape and do some changes on filesystem size.

For more information about Ignite/UX, you can goto this url :

Hope this can help you.

Merry Xmas & Best Regards,

Hi it seems he doesn't want to use IGNITE !! .....

You can extend root from LVM maintance mode by relocationg some PE's after the root logical volume somewhere else (may be another disk or end of the same disk....)

There are already some posts to extend root and stand filesystems ; i need not explain the full procedure how to do it !! search for it in the forum.

Or if you think u need little more guidance , please post o/p of the following commands so that I can make a plan for you !

strings /etc/lvmtab
vgdisplay -v /dev/vg00
ioscan -fnC disk

Good luck ...... It takes less time than IGNITE ,and you have an opertunity to learn HP-UX behaviour in LVM maintanance mode.... I would choose this way of doing as i do not get many chances to do it !!. Taking an ignite / fullbackup is always good...
