How to increase root file system size in HP-ux 11i V2?

All guru's need help.

[Pete Randall]

Since the root file system (and /stand and swap) have to be contiguous, this is nearly impossible to do without using an ignite backup tape to re-create your system.

this may shed some light on it.

Why don't you start by sending us some information:

Please run a vgdisplay -v on your vg00

If you have lvols please run also a lvdisplay -v on those logical volumes.

Do you have space to extend filesystem?

Are you going to use new disk?

Regards,

Jaime.

I am doing it on Hp workstation

I have added 17.2GB PV to vg00

now am unable to extend / on this newly added PV in vgoo.

[Geoff Wild]

You can't increase root that way - has to be contiguous.

Best way is to ignite your workstation - and resize the partitions.

Please post the vgdisplay -v vg00

It may be possible to resize without ignit - depending on your layout.

Still, ignite is the best and prefered and supported way.

Shalom,

Note, there is no such thing as a 32 bit install of HP-UX 11i v2.

It is 64 bit only.

The only reliable way to expand root is to do a make_tape_recovery or make_net_recovery followed by a recovery of the system.

There is an option to do keyboard intervention from the console that permits expansion of the root fs.

Hi,
I think that if you have added a new disc to the vg then you can free space with the command pvmove to move lvols after lvol3 (root fs) to the new disk.

Example:

pvmove -n /dev/vg01/lvol4 /dev/dsk/cXtXdX /dev/dsk/cYtYdY

/dev/dsk/cXtXdX (source_path)
/dev/dsk/cYtYdY (destination_path)

and so for lvol5 ...

Then you can extend the root filesystem.

Or you can mirror the lvol4 lvol5 ... to new disk and then reduce the mirror from source_disk to free space after the root lvol.

I have not never tried this solutions personally, I ask confirmation for this to others.

Enrico's solution may well work, but I wouldn't undertake anything like this without having an ignite backup. And if you've got an ignite backup - do I need to finish this sentence?

Mark Syder (like the drink but spelt different)

[Geoff Wild]

lvol3 is root I assume (confirm with bdf) and lvol4 is probably home.

In that case, you could mv home to a new home (create a new lvol then temporarily mount it to something like /newhome, then copy /home to /newhome, unmount /home and /newhome, then mount the "new" home to /home)

After that, lvremove lvol4, then you can extend / (lvol3).

lvextend -L 882 /dev/vg00/lv0l3
fsadm -b 882M /

I would take the only supported and most reliable option: via Recovery Tape (Ignite)

1. Create a system recovery tape using make_net_recovery or make_tape_recovery -I
2. Boot from archive
3. Resize the logical volumes in the Ignite interface
4. Allow Ignite to recreate vg00 using new sizes, and restore all the data.
