Hi keen folks!

how can I increase my /var directory without reformating my system.
I am using RHEL4

[root@localhost var]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup_ID_17452-LogVol1
1008M 205M 752M 22% /
/dev/sda3 190M 15M 166M 8% /boot
none 2.0G 0 2.0G 0% /dev/shm
/dev/mapper/VolGroup_ID_17452-LogVol2
496M 15M 457M 4% /tmp
/dev/mapper/VolGroup_ID_17452-LogVol5
154G 3.1G 143G 3% /usr
/dev/mapper/VolGroup_ID_17452-LogVol4
496M 471M 0 100% /var
/dev/mapper/VolGroup_ID_17452-LogVolHome
123G 3.4G 114G 3% /home
[root@localhost var]#

You could add another partition into that logvol as one solution. Perhaps shrink the home logvol a bit and use that.

You have to use lvextend command for extending your logical volume

In case, if you're having some space left on your current volume group, use following command

If you don't have any space left on your volume group, create new physics volume, add it to your vol group and then extend your logical volume

pvcreate /path/to/new/dev
vgextend lvname /path/to/new/dev

And then you can extend your logical volume because your VG is now having space added to it.

Hi thanks to all reply!


To n03x3c: can you give me the exact command on how to do it?

suppose I want to add 20G on /var? here's my fdisk-l command thank you.

can you fill-up your response with the correct Volume that am I going to type what I mean fill-up all your syntax :-)?

[root@localhost ~]# fdisk -l

Disk /dev/sda: 499.9 GB, 499999834112 bytes
255 heads, 63 sectors/track, 60788 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda5 16331 60788 357108853+ 8e Linux LVM

according to man lvextend:
Examples
"lvextend -L +54 /dev/vg01/lvol10 /dev/sdk3" tries to extend the size
of that logical volume by 54MB on physical volume /dev/sdk3. This is
only possible if /dev/sdk3 is a member of volume group vg01 and there
are enough free physical extents in it.

which [/dev/sdk3] am I going to use in my case? is it sda4 or sda5?

Ofcourse you're going to use sda5 in your case.

Extended partition hold all partition after it, so neva use extended partition. If you del it, all partition after it will be gone.

And the command you found on man page, let you extend your /var on specific partition, if you're having logical volume management tool on your system, you will see the logical as well as physical view of your volumes and you will understand it better.

The first thing I would do is remove all of the old log files under /var. Log files can fill up a partition of < 500MB pretty fast if they are not managed. But if you have a regular process that rotates them and archives them, or simply removes the old ones, you may be fine without adding space.

I canceled this post.
I will post it again.
Thanks.

I google to internet I am currently reviewing that links hope others can test it also.

here's another link to review folks! http://www.redhat.com/magazine/009jul05/features/lvm2/


I read RHEL4 use LVM2

I tried lvextend here's the error message.


[root@localhost /]# lvextend -L+200G /dev/VolGroup_ID_17452/LogVol4

Extending logical volume LogVol4 to 200.50 GB
Insufficient free space: 6400 extents needed, but only 5772 available

what am I going to do next?

quote from no3x3c
kindly fill this up according to my need. thanks



the following are my HDD partitions information:

So you only have 180-181G free? Try extending by less - but first, you currently have 1/2G and you are planning to increase this to around 200G. That's a 400x increase. Are you sure you want it that large?

Assume you add new partition or you already have one sda5 that you need your extended data store into.

Cancelled post.

Your /usr partition appears to be quite large (154 GB).
I would copy the entire /var directory (using cp -dpR to keep all permissions intact) to /usr (so it will be at /usr/var), renaming the current /var to /var.bak (or anything), and then create a softlink in /var pointing to /usr/var
Your old /var location (~ 500 MB) can then be used for any other purpose.

I created a website and I host it on my own. I put my website in /var/www and oracle to another user, third party to another user.

I run LAMPS ... now I am out of space in /var coz of a lots of very big log files... including mysql database data residing in /var/lib/mysql/data....is in /var directory ...so all are using /var.

anything you can suggest to me friend what am I going to do?

What is the effect of pvcreate and vgextend? can i increase my /var directory after this?

friend can you give me a complete list of command plz.

1. instruction 1
2. instruction 2
3. instruction 3.......until finished.

kindly give me the details of the command because it is very dangerous to edit this HDD PARTITION it may coz a lost of data to me. Hope you understand.

try to be complete pls.
