Is there a different way (simple one) on how to increase the /tmp?

Ok. Please issue the following commands:

pvdisplay
pvs

vgdisplay
vgs

lvmdiskscan

df -hT

Hi tamirmilo,

Exatly your system's / partition in almost, you dont have saperate /tmp partion so it is taking space from the / partion.

Now bottom of the line is either you have to increase your / root partion or you have to add separate disk to create separate /tmp partition.

After looking your output of df -k, I can suggest you a way. Its upon you to take it or not.

You have fresh partion and dont have data on it.

/dev/sdb1 1032117684 204276 979484884 1% /ora_products

so you can repartion the disk /dev/sdb and create two partition on it. One small 2GB or 3GB partition for /tmp and rest you can keep for /ora_products.

Please let me know, if you want ot do the same and need any assistance.

Hi upanwar farzanj ,

FYI, It is all under vmware.

@upanwar:
I would like to use the "huge" partition of 1 tera as a "tmp" area.

Thank you very much experts

As per the details you have given there is no scop to increase the space so I am giving you steps to repartion /dev/sdb.

ASKER

ok. i am following you. thx

You can simply use parted to repartition it.

@farzanj:
I need the commands... i am too scared to do it. thx

# sudo fdisk /dev/sdb

To mount these partion after reboot please make an enty in fstab file as well as given below.

/dev/sdb1 /tmp ext3 defaults 1 1

/dev/sdb2 /ora_products ext3 defaults 1 1

Ooops, one correction.

When second time n then choose 2 instead of 1, because 1 partion is already created.

@upanwar:
REsource is busy.. what shall i do ? thank you very much
[root@jnora11g /]# sudo fdisk /dev/sdb

The number of cylinders for this disk is set to 130541.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): d
Selected partition 1

Command (m for help): w
The partition table has been altered!

Calling ioctl() to re-read partition table.

WARNING: Re-reading the partition table failed with error 16: Device or resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.

You can simply resize your /dev/sdb1.

I will have to do interactive work with you.

First you should resize the filesystem on /dev/sdb1

resize2fs /dev/sdb1 -20G

Sorry, too late. You already deleted your partition.

Now issue the command.

# partprobe

and follow the rest steps.

Hey Farzani,

The command you have shown is to resize the filesystem, still partition needs to be resized as well to create free space.

ASKER

Looks like we will have to do it interactively.

[root@jnora11g /]# resize2fs /dev/sdb1 -20G
resize2fs 1.39 (29-May-2006)
resize2fs: invalid option -- 2
Usage: resize2fs [-d debug_flags] [-f] [-F] [-p] device [new_size]

Ok, if you still have the filesystem intact, you can do

resize2fs /dev/sdb1 <SIZEinGB>G

So this should be the size you want after you reduce your filesystem. So if currently your size is 985G and you want 955G then
resize2fs /dev/sdb1 955G

Hope that works.

Next step would be with parted

@Upanwar:
You are absolutely correct. First you resize file system. If you don't then you damage it. Next you use parted to reduce the partition size.

ASKER

guys.. i am confused. THis is a vm. I can go back to the state before if needed.
you say:

Now issue the command.
# partprobe
"and follow the rest steps." -- from where ? just after the partprobe above?

Now execute below given commands.

# partprobe

# fdisk /dev/sdb

Command (m for help): n
Command action
e extended
p primary partition (1-4)

p
Partition number (1-4): 1
First cylinder (1-xxxxx, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-xxxxx, default xxxxx): +10G

Command (m for help): t
Select id 83

Command (m for help): n
Command action
e extended
p primary partition (1-4)

p
Partition number (1-4): 2
First cylinder (1-xxxxx, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-xxxxx, default xxxxx):

Command (m for help): t
Select id 83

Command (m for help): w

# sudo partprobe

# sudo mkfs.ext3 /dev/sdb1

# sudo mkfs.ext3 /dev/sdb2

# mount /dev/sdb1 /tmp

# mount /dev/sdb2 /ora_products

To mount these partion after reboot please make an enty in fstab file as well as given below.

/dev/sdb1 /tmp ext3 defaults 1 1

/dev/sdb2 /ora_products ext3 defaults 1 1

You can define the size for /tmp as per your requirement.

I am leading you a complete different direction than expert Upanwar. If you followed his way already and deleted the partition, my way is pointless. My way was mean to save you from deleting partitions and recreating them -- saving data as well. But if you deleted it already, you can follow the rest of steps by him.

ASKER

i already deleted. although i have a copy of the vm and snapshot

Since it was a blank partition so data was not a concern.

ASKER

actually, i had data... my big mistake..
I think i will revert back to the image

ASKER

@farzanj, i think i will have to use your method of not deleting the data in the partition...

I guess the output of df -k says that you was not having data.

But noe you have doubt so restore the VM again and follow the steps from Farzani.

@ Farzani: Please take care. :)

Well, appeared to me there was less than 200M of data (excluding some metadata). Upanwar already worked with you. We both wanted to help. Both ways would have worked. I'm sorry, was just trying to help. At the end, you should get help what you wanted.

Say something. What do you want to do?

ASKER

Guys. thanks for your help I will complete it all tonight.
