Today I hired a VPS with 12GB HD.

3GB for the system disk, 9GB left;

It was created two partitions: 
One: /dev/xvdb1 == /home
Two: /dev/xvdb2 == /var

 Data were transferred to each new partitions  with the command
"find . -depth -print0 | cpio –null –sparse -pvd /srv/newhome/" by
tutorial
http://helpforlinux.blogspot.com.br/2009/0...

After all is done and reboot, I went to see the list of partitions

--------------------------------------------------
#mount -v
/dev/xvda1 on / type ext4 (rw,noatime,errors=remount-ro)
tmpfs on /lib/init/rw type tmpfs (rw,nosuid,mode=0755)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
udev on /dev type tmpfs (rw,mode=0755)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=620)
/dev/xvdb1 on /home type ext4 (rw)
/dev/xvdb2 on /var type ext4 (rw)
/dev/xvdb1 on /srv/Home type ext4 (rw,nosuid,nodev,noatime)
/dev/xvdb2 on /srv/Var type ext4 (rw,nosuid,nodev,noatime)
tmpfs on /var/gandi type tmpfs (rw,mode=0755,size=22000)

--------------------------------------------------

Realize that you have:

/dev/xvdb1 on /home type ext4 (rw)
/dev/xvdb2 on /var type ext4 (rw)
/dev/xvdb1 on /srv/Home type ext4 (rw,nosuid,nodev,noatime)
/dev/xvdb2 on /srv/Var type ext4 (rw,nosuid,nodev,noatime)

* the ideal is to run out the last 2 lines

--------------------------------------------------
My fstab

#cat /etc/fstab 
/dev/xvda1    /                 ext4    rw,noatime,errors=remount-ro  0    1
devpts        /dev/pts          devpts  defaults      0 0
none          /proc             proc    rw,nosuid,noexec  0    0

/dev/xvdb1    /home		ext4	defaults	0	2
/dev/xvdb2    /var		ext4	defaults	0	2

--------------------------------------------------

They know how to not let it hit the record repeated?

excuse the English.

Hello,

I advise you not use partition on your virtual disk. This will hurt the
input/output performance.
You can create 2 virtual disks, one for your home and one for your var which
will be mounted by gandi-mount during the boot process in /srv/<your-label>/

If you want to manually manage your disk on your virtual server, you can
disable the udev rules which automatically mount the additional virtual disk
to /srv/<disk-label> by commenting the line containing
RUN+="/etc/gandi/manage_data_disk.py" in /etc/udev/rules.d/86-gandi.rules

This way, virtual disk will be attached to your server by our Xen
infrastructure during the boot and will be shown by the kernel in
/proc/partitions. Virtual disks however will not be mounted. 

A couple of warning about adding additional disk entry in your /etc/fstab :
 * if you detach a disk and reboot your server, the boot will hangs with an
emergency root console complaining the disk is missing.
 * if you move all data from /var to an additional disk, you may experienced
probleme during the boot. I advise you to move only none boot essential data
to your additional disk. For example : 
/var/log /var/cache /var/lib/mysql to an additional disk which could be
labeled /more.space. By creating softlink back to /var (/more.space/log ->
/var/log) you can keep a compatibility with the current setup.


my 2 cents.

It would be better then having it all in "/"? you advise that?

Do you have a tip for safe partitioning Gandi VPS

My advice would be : keep the system disk to the default size and add
additional disk with the necessary space for your user or application. 

I prefer to repeat the information from my previous post but please do not
make partition on the virtual drive which will be attached to your virtual
server. You will get a I/O performance loss.

Example :
(first disk /dev/xvda1) / -> /usr, /etc, /tmp, /lib, ...
(second disk /dev/xvda2) automatic swap
(third disk /dev/xvdb) /srv/<your_label> ->
/srv/<your_label>/site/www.example.tld, /srv/<your_label>/postgresql, ...
(fourth disk ...)
(...)

Nicolas great,

thanks for your answer.
Virtualization is a new thing for me.
