Hey, good to find someone who aegres with me. GMTA.
+
===Expanding disk===
 +
This is a step by step guide that works with partitions, so be very careful, and keep in mind that though this is a guide and it's been tested, it's not guaranteed that it'll work on your system, (make a backup of your VM just to be safe).
 +
 
 +
This guide will only show how to expand the original 60GB disk where the SiT website + attachments are stored.
 +
 
 +
In this example I'll upgrade the drive to 80GB. I've typed in 80GB in the VM player editing the Hard Disk 2, see how [[VM#Expanding_the_logical_disk_in_VM|below]]
 +
 
 +
====Expanding the logical disk in VM====
 +
First you need to make the logical disk larger through the VM, this is done like this (guide from VMWare Player).
 +
* Start VMware Player
 +
* Right click the SiT VM '''SiT_V3.62'''  and click ''Virtual Machine Settings''
 +
* Left click ''Hard Disk 2'' and you'll see some options to the right side of the window.
 +
* Click the button ''Utilities'' and click ''Expand...''
 +
* Enter the new size and click ''Expand'' (I've written 80GB for this example)
 +
* Click ''OK'' and start the SiT VM
 +
 
 +
====Expanding the drive in Ubuntu====
 +
First of all, ''Make sure that you've backed up all the data from /var/www''
 +
 
 +
Start by checking that the OS actually sees the new size.
 +
<code><pre>
 +
sudo fdisk -l
 +
</pre></code>
 +
 
 +
Alot of text is output, but I see on one of the lines
 +
 
 +
<code>
 +
Disk /dev/sdb 85.9 GB, 85899345920 bytes
 +
</code>
 +
 
 +
Start by unmounting the extended drive
 +
<code><pre>
 +
sudo umount /var/www
 +
</pre></code>
 +
 
 +
Delete the partition and remake it again (all data should still be there when done)
 +
<code><pre>
 +
sudo fdisk /dev/sdb
 +
</pre></code>
 +
 
 +
* d  # This will delete the partition
 +
* n  # Create new partition
 +
* p  # Create primary partition
 +
* 1  # Choose partition number 1
 +
* <nowiki><enter></nowiki>  # Select first cylinder (default) 1
 +
* <nowiki><enter></nowiki>  # Select last cylinder (default) 10443 (this size might differ depending on your choice of size)
 +
* t  # Change the type of partition
 +
* 8e # Choose the Linux LVM
 +
* p  # Display the chosen settings
 +
* w  # Write changes to disk
 +
 
 +
If you get an error that there device is busy, reboot the VM.
 +
<code><pre>
 +
sudo reboot
 +
</pre></code>
 +
 
 +
Resize the physical volume, to its maximum (other options are available but not explained here)
 +
<code><pre>
 +
sudo pvresize /dev/sdb1
 +
</pre></code>
 +
 
 +
Resize the LVM drive (choosing 80GB you'll need 1 extend, which is why I've chosen 79.99GB, another option is to ''sudo lvextend -L+20GB /dev/webroot/www''
 +
<code><pre>
 +
sudo lvextend -L79.99GB /dev/webroot/www
 +
</pre></code>
 +
 
 +
Now the last thing we need to do is resize the filesystem
 +
<code><pre>
 +
sudo resize2fs /dev/webroot/www
 +
</pre></code>
 +
 
 +
Now we can see if it's actually the chosen size
 +
<code><pre>
 +
sudo df -h
 +
</pre></code>
 +
 
 +
This is how my system looks like after resize
 +
 
 +
<pre>
 +
Filesystem            Size  Used Avail Use% Mounted on
 +
/dev/mapper/sit-root  14G  1.2G  13G  9% /
 +
none                  244M  184K  244M  1% /dev
 +
none                  249M    0  249M  0% /dev/shm
 +
none                  249M  48K  249M  1% /var/run
 +
none                  249M    0  249M  0% /var/lock
 +
none                  249M    0  249M  0% /lib/init/rw
 +
/dev/sda1            228M  34M  182M  16% /boot
 +
/dev/mapper/webroot-www
 +
                      79G  200M  75G  1% /var/www
 +
</pre>
