Jump to: navigation, search

Rocks 5.0 (V) for i386 and x86_64 architectures has been released on 30th April. Thus we have used a released version for the second iteration.

[edit] Partition table

We recreated partitions for the iteration 2. Previous layout has been described here.

Rocks 5.0 ISO file has been connected via IPMI/BMC tool to the Headnode. The Headnode had been rebooted with option: 

frontend rescue

After setting Network parameters a window with 3 options appeared on a screen. To open shell one should choose "Skip".

The following set of command had been executed to recreate partitions: 

# to delete previous partitions
parted /dev/sda rm 7
parted /dev/sda rm 6
parted /dev/sda rm 5
parted /dev/sda rm 3
parted /dev/sda rm 2
parted /dev/sda rm 1
# to make partition table MBR based (instead of GPT which is unsupported by grub
parted /dev/sda mklabel msdos
# to create / partition
parted /dev/sda mkpart primary ext3 0 10GB
# to create /tmp partition and make the remaining space less than 2TB
parted /dev/sda mkpart primary ext3 10GB 50GB
# to create extended partition for remaining space
parted /dev/sda mkpart extended 50GB 2247GB
# to create /var partition
parted /dev/sda mkpart logical ext3 50GB 60GB
# to create /export partition for the remaining space
parted /dev/sda mkpart logical ext3 60GB 2247GB
# to make first partition bootable
parted /dev/sda set 1 boot on

[edit] Installation of Rocks

After rebooting via BMC console a standard mode to install Rocks had been chosen: 

frontend

The following rolls had been selected:

  • area51
  • base
  • bio
  • ganglia
  • hpc
  • java
  • kernel
  • os
  • web-server

Domain name of the production cluster is hpc-bestgrid.auckland.ac.nz

Public IP Address is 130.216.189.80

The installation had been finished without any issues.

Network interfaces had been swapped according the this note.

[edit] Convention for IP addresses and node names of the Cluster

The following convention for IP addresses and node names had been admitted:

  1. compute nodes named as compute-1...compute-10
  2. eth0 interfaces of each node have IPs in a range 10.0.1.1-10.0.1.10
  3. aliases for eth0 interfaces are compute-1...compute-10
  4. eth1 interfaces of each node have IPs in a range 10.0.2.1-10.0.2.10
  5. aliases for eth1 interfaces are mgr-1...mgr-10
  6. BMCs of each node have IPs in a range 10.0.3.1-10.0.3.10
  7. Nodes should have IPs and names assigned in their physical order in racks
