After installing the telescope rails for my new HP DL140G3 adding a disk has become fun. No removing from the rack any more; just pulling the server out; open the safety screw at the back; removing the top cover of the server with a slight yank. The disk are to be stored in two trays on the left side which can also be removed with out any tools. Connect the cables; put the tray back and fasten the screw and we start configuring the disk.
I have build in two 1 TB disks. In order to manage the 2TB flexible i am using logical volumes. The standard allocation of disspace looks like this:
[root@thunder ~]# df -h
Filesystem Size Used Avail Use% Mounted on
50G 2.4G 45G 5% /
tmpfs 7.8G 0 7.8G 0% /dev/shm
/dev/sdb1 485M 32M 429M 7% /boot
50G 180M 47G 1% /home
394G 199M 374G 1% /data
9.9G 750M 8.7G 8% /opt
50G 180M 47G 1% /root
Since i don't like to have the root user home directory on the root file system where the operating system is located i am installing normally a group lv_admin and mount it on /root. If root logs in he working on his own logical volume group.
The volume group lv_home is intended as /home and lv_data as /data where i am storing computation results.
