  • IP Address Farm: 10.0.0.243 (farm)
  • IP Address UNH: 132.177.88.228 (unh)
  • IP Address RAID: 10.0.0.99 [1]

Software and Services

IPTables

Pumpkin uses the standard iptables configuration.

Splunk

Pumpkin is the master Splunk node and stores all of the splunk data in /data1/splunk. If you want to access the Splunk web interface it is at https://pumpkin.unh.edu:8000 (if you're connected via the Farm), or you can forward port 8000 over SSH.

NFS

Pumpkin shares two data stores (/data and /scratch) over NFS. They can be accessed at /net/data/pumpkin and /net/data/scratch from any machine.

RAID

The RAID is currently split.

Disk 1 to 17 @ 4TB
  • Disk 17 is hot spare
  • RAID Set #00
  • Volume: data lun(0/0/0) is RAID6 = 56 TB
  • Translates to /dev/sda1 mounted on /data
Disk 19 to 24 @ 750 GB
  • RAID Set #01
  • Volume: scratch lun(0/0/1) is RAID0 = 4.5 TB
  • Translates to /dev/sdb1 mounted on /scratch
Disk18 is N/A

The RAID card can be monitored at http://10.0.0.99/ login as "admin" with a password that is described on the RAID page.

Software RAID

There are 2 internal drives in Pumpkin forming a software RAID. Note these are *not identical* partitions on the drives, so the RAID does not look symmetrical. Blame the installer.
