Azure Ubuntu: Why is the temp drive mounted to /mnt?

Question

In azure, i have installed a Ubuntu Server 12.04 LTS. After the first boot, i got the follwoing output from df -h

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        29G  879M   27G   4% /
udev            328M   12K  328M   1% /dev
tmpfs           135M  248K  135M   1% /run
none            5.0M     0  5.0M   0% /run/lock
none            337M     0  337M   0% /run/shm
/dev/sdb1        20G  172M   19G   1% /mnt

According to Azure local disk - where'd it go? (Linux VM), /dev/sdb1 is the local temp disk.

What is the reason that the temp disk is automatically mounted to /mnt, and is it possible to change the mount point of /dev/sdb1?

edit: This is how the fstab looks after installing, so i cant see how to change the mount point of /dev/sdb1

Answer 1

It is possible to change the mount point of /dev/sdb1 if you have the windows azure agent installed. In RHEL/centos systems, the configuration file is located in /etc/waagent.conf

For RHEL/centos this agent is provided by the openlogic Repo and is titled: WALinuxAgent.noarch 2.0.11-1 @OpenLogic
