root partition to be increased

[fizan]

team,

online jfs is not installed, while installing the os with guided installation i installed, so the root,usr,tmp are all only 500MB now i want to increase the space for root partition bcoz only 258MB free as of now, kindly explain how to increase the size?

[Torsten.]

Probably the best would be to take an ignite backup and adjust the size during restore.

[fizan]

as of now there is no ignite backup avail, but the server is not in production so any idea to increse by going to single user mode?

[Michal Kapalka (mikap)]

hi,

there are some unofficial procedures how to do it, but the best way is to make an ignite and restore with new size as Torsten recommend.

Here is the unofficeial way beautifully described by James.

But still ignite option is good, you can go ahead and take ignite and then restore it.

Root and boot cannot be extended so easily even in single user mode, because they have to be continuous. But normally both will grow so much during normal operating.
All others (tmp, usr, opt, ...) can be incresed in single user mode.

[Torsten. · Accepted solution]

Sorry, should be

...But normally both will *not* grow so much during normal operating...

Hi,

Though you have online JFS you can't extend root file system, to extend the same there is a long procedure to do the easiest one is take a Ignite backup and restore it in interactive mode and there you give the new size of root file system.

thanks for all of your suggestions,

Do you have a tape drive?

[fizan]

No we dont have tortsen.

[Michal Kapalka (mikap)]

hi,

you could use ignite server, if you dont have a physical tape drive for ignite backup.

OR if this system is 11.23 and higher you could use DRD.

Hi Fizan,

If you have any external tape drive in any server, you can connect it to this server and take ignite backup.

[fizan]

so after taking an ignite restore, then again while installing the OS again we have to go via the "ADVANCED INSTALLATION" right and provide the needed size over there correct. so for that first need to install the ignite tool in the server right?

[R.K. #]

Yes..

you need to install ignite first. From here:
https://h20392.www2.hp.com/portal/swdepot/try.do?productNumber=IGNITEUXB

Take backup. You can use the "-i" option while taking ignite backup so the the booting will always be interactive.
Then boot from ignite tape and go for interactive mode. Go to file system menu, i suppose, and change the size.

Regds..

You can have a look on Avinash's reply:

That might be helpful.

Hi,

YES...
then while restore choose "ADVANCED INSTALLATION" there you define your new size of root and other file systems.

Hi,

Most recommended method from Hp is to take the ignite backup, make sure latest ignite software â C.7.8.201 â installed in serve.

(1) #ioscan â fnC tape ( to detect the path of tape it should be /dev/rmt/0mn )

(2)
# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

To take the ignite backup of root VG.

(3) Once it is completed you can verify successful completion in /var/opt/ignite/recovery/latest/recovery.log

(4) Boot the server from tape and then select â Advance installation mode â

Here you can modify new size of root.

(5) Take the full system offline backup before doing ignite backup and restoration (to be on safer side.).


Regards,
Subodh.

Hey,

Geoff Wild have made a site for tips and tricks:

And this is the trick you need:

This does not shed new light on the issue but anyway.

hi Subodh,

while taking the ignite backup, make_tape_recovery how to backup as a boot image so whether we have to give any option like -b so that while booting from tape it will directly boot as boot image setup.

[R.K. #]

No need of -b option here

You can use..

# make_tape_recovery -x inc_entire=vg00 -I -a /dev/tape_device_name
The above command includes the complete vg00 for backup

-I (upper case i) : Causes the system recovery process to be interactive when booting from the tape. By default, when the systems boots from the recovery tape, it will allow ten (10) seconds to interrupt the automatic recovery process in order to make modifications interactively.

[Kanagaraj]

Fizan,

You can store boot image files on Tape or Ignite server.

Simply take OS full backup of the server on Tape by following command make_tape_recoevery -A -I -v -x inc_entire=vg00 -a /dev/rmt/0mn(This is tape drive path)

you can check the path of the tape drive,

ioscan -fnC tape

once completed backup.

restore the ignite backp by booting the server from Tape drive and select hpux installation and advanced option. Then you can increase root / file system partion size from file system tap.
