Gourd/Einstein Migration Plan

This page is for notes on the steps needed in order to fully migrate from the current Einstein system to the new Gourd hardware and Einstein System.

Gourd

Gourd will serve as the file server for home folders and mail, as well as the Virtualization host for Einstein and other Virtual Machines such as Roentgen and Corn

Migration Checklist for Gourd

1. Drives and RAID
   1. Configure hard drives and RAID arrays as outlined here
      • Copy the 250GB system drive pass-thru disk to a 250GB RAID 1 volume on two 750GB disks (Slots 1 and 2) done
      • Remaining 500GB on each drive spanned to a 1TB RAID 0, mounted on /scratch done
      • Two 750GB disks as pass-thru, set up as software RAID (Slots 3 and 4) done
      • 500GB RAID 1 for home folders (/dev/md0) mounted on /home done
      • 100GB RAID 1 for Einstein's /var/spool/mail (/dev/md1) mounted on /mail done
      • 150GB RAID 1 for virtual machines (/dev/md2) mounted on /vmware and added as a local datastore in VMWare done
      • Two 750GB drives in Slots 7 and 8 as hot spares done
2. System Setup
   1. NFS
      • Set up NFS Shares for /home and /mail done - Currently /mail share only accessible by Tomato, need to change to Einstein at switchover
      • Create npghome.unh.edu alias interfaces on Gourd
        • Add to DNS configs done - Assigned farm IP of 10.0.0.240
        • Needs to be added to Servers in LDAP for iptables to work
   2. Change Automount configuration in LDAP (possibly also on clients) to use npghome:/home instead of einstein for /net/home -- TEST and warn users before switchover
   3. Backups
      • Change rsync-backup.conf so that /mail and /home get backed up
      • Create new LDAP group for backups so that gourd doesn't get backed up a second time as npghome - change backup script in Lentil to use new group
   4. Virtual Machines
      • Copy virtual machines from Taro to /vmware on gourd
        • Corn done
        • Roentgen
