Hello,

I searched google and then this forum but I don't think I found anything closely related within the first 3 pages of either. I did however find the appropriate (newbie) forum

I followed this walkthrough for adding space to /tmp which was at 91%. I can't post URLs yet, so I will append the walkthrough at the bottom

I am running

dell intel 2.66 4gb
CentOS Elinux ES 5
cPanel stable
Symantec Endpoint PC 11.x

So, my /tmp was getting to full and I followed th walkthrough above. Step 9 resulted in the file is too large.

I couldn't just stop so I moved to 10.

I receieved this output:

[/]# mount -o remount /tmp
[/]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 7.8G 3.1G 4.3G 43% /
/dev/sda8 195G 15G 171G 8% /home
/dev/sda3 7.8G 7.3G 119M 99% /usr
/dev/sda2 9.7G 1.9G 7.4G 21% /var
/dev/sda1 122M 28M 88M 24% /boot
none 2.0G 0 2.0G 0% /dev/shm
/usr/tmpDSK 996M 836M 109M 89% /tmp
/dev/sda6 996M 836M 109M 89% /tmp


Woops. I can see what I did wrong. I didn't research enough ahead of time. I can what I didn't do. Wait, until I had more information and possibly asked before doing.

I won't make that mistake again.

Can someone please help me research on how to:

Fix the none to /tmp
move the backup tmpDSK into tmp
rm the tmpDSK
fix /usr

shame on me.

Code:
1)Stop MySql service and process kill the tailwatchd process.

[ ~]# /etc/init.d/mysqld stop
Stopping MySQL: [ OK ]
[ ~]#pstree -p | grep tailwatchd
Find the tailwatchd process id and kill it
[ ~]# kill -9 2522

2)Take a backup of /tmp as /tmp.bak
[ ~]#cp -prf /tmp /tmp.bak

3)Create a 2GB file in the avaliable freespace

==============================
[ dev]# dd if=/dev/zero of=/usr/tmpDSK bs=1024k count=2048
2048+0 records in
2048+0 records out
2147483648 bytes (2.1 GB) copied, 73.6908 seconds, 29.1 MB/s
==============================

[ dev]# du -sch /usr/tmpDSK
2.1G /usr/tmpDSK
2.1G total

4)Assign ext3 filesystem to the file
====================================
[ dev]# mkfs -t ext3 /usr/tmpDSK
mke2fs 1.39 (29-May-2006)
/usr/tmpDSK is not a block special device.
Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
262144 inodes, 524288 blocks
26214 blocks (5.00%) reserved for the super user
First data block=0
Writing inode tables: done
Creating journal (16384 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 25 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
====================================
5) Check the file system type:-

[ dev]# file /usr/tmpDSK

/usr/tmpDSK: Linux rev 1.0 ext3 filesystem data (large files)
Note:-
=====
You may also use the following comands for making ext3 file system on a file:
[ dev]#mkfs.ext3 /usr/tmpDSK
[ dev]#mke2fs /usr/tmpDSK

6)Unmount /tmp partition

[ dev]#umount /tmp

7))Mount the new /tmp filesystem with noexec

[ dev]#mount -o loop,noexec,nosuid,rw /usr/tmpDSK /tmp

8) Set the correct permission for /tmp

[ dev]# install -d –mode=1777 /tmp
[ dev]# ls -ld /tmp
drwxrwxrwt 3 root root 4096 Feb 6 08:42 /tmp
( you may use the command chmod 1777 /tmp for doing the same )
==========================

[ dev]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda9 28G 6.4G 20G 25% /
/dev/sda8 99M 10M 84M 11% /boot
tmpfs 500M 0 500M 0% /dev/shm
/usr/tmpDSK 2.0G 68M 1.9G 4% /tmp
==========================
7)Restore the content of old /tmp.bkp directory

[ dev]# cp -rpf /tmp.bak/* /tmp

8) Restart the mysql and tailwathchd services.

[ dev]# /etc/init.d/mysql start
[ dev]# /scripts/restartsrv_tailwatchd

9)Edit the fstab and replace /tmp entry line with :-
=========================================
/usr/tmpDSK /tmp ext3 loop,noexec,nosuid,rw 0 0=========================================
10) Mount all filesystems

[ dev]#mount -a

Check it now:-
============================
[ ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda9 28G 6.4G 20G 25% /
/dev/sda8 99M 10M 84M 11% /boot
tmpfs 500M 0 500M 0% /dev/shm
/usr/tmpDSK 2.0G 68M 1.9G 4% /tmp
