MahPIC
Introduction
MahPIC is a server that was purchased and installed in the Boyd datacenter by Jessica Kissinger and her group. Our commitment to the server is high-level administration. This node facilitates the collaboration of the University of Georgia with the project members and participating universities of Emory and Georgia Tech. We assist their existing team with their technical needs as well as acting as a proxy for their requests to EITS. It runs CentOS 6.4, has Oracle databases and is connected the zcluster over the internodal network.
In order to back up the data, the storage unit uses NFS to connect to a SunFire storage unit named thumper3. This unit uses rsync to back up its contents to an offsite SunFire named thumper4. The offsite location is the Health Sciences building located on the Health Science Campus (HSC).
Jeremy DeBarry is the project manager, Vishal Nayak is the system administrator and Alan Gingle is an Oracle administrator.
Access
DNS Name: mahpic.uga.edu Login: SSH
Physical Description
The server is an HP ProLiant DL380 G7 with an attached storage array providing 6TB of storage. It's located on the Kissinger row in the back of the Boyd datacenter.
Configuration
MahPIC is a straightforward Linux installation with access to our networks. The 6TB storage array is partitioned using LVM2. These partitions are shrunk and grown and new LVM partitions are created and mounted as they request. An NFS mount point from thumper3 is mounted under /mnt/backup on the unit.
Firewall
MahPIC has made many firewall requests. When their team makes a request, we use the request form on infosec.uga.edu to grant them.
Routine Tasks
Adding an LVM partition
Note: The 6TB volume is identified as /dev/sdb1 and already has an existing VG.
