Setup

As of 2019-04-24 the ssh port of the main host (the physical server) is 2222 and there is only one non-root account on it and can only be accessed via key access. At this time only wildintellect, strk, robe, martin, pramsey and jef have their keys installed

So to SSH - ssh tech_dev@osgeo7.osgeo.osuosl.org -p 2222

As of 2020-12-20 some configurations of this machine are deployed using AnsibleDeployment

• Ubuntu 18.04 (Release Notes). more details about install steps

 DONE: Installed 18.04.1 on the Samsung 512GB MZVKW512HMJP (whole drive), and only installed OpenSSH (140.211.15.30, 140.211.15.57)

• • ZFS DONE
• OS and lxd are installed on SAMSUNG regular ext4 partition (500GB).

• DONE Created an LXD ZFS pool called osgeo7 that takes up the other disks in a RAID 10 config (16 TB total (of the 32 TB)). Note we went with simple single ZFS pool RAID 10 takes up the remaining disks (Non-SAMSUNG).

• • • • Additional Reference
      • Installing Ubuntu on ZFS root using terminal
      • Installing Ubuntu with ZFS root using Ubiquity
    • Root pool on spinning disks, either as raid-z2 or a pair of 2 device mirrors? (How do we decide?)
    • ZIL slog on mirrored Optane drives, consider placing the boot pool ('bpool') here as well.
    • L2ARC on M2 SSD drive.
    • If using legacy BIOS boot mode, install grub to all devices; UEFI requires additional partitioning.
  • LXC/LXD - storage options we'll go with zfs (need to decide how big of storage),
    • also the fact btrfs allows going back to older snapshot, does zfs have a comparable feature, or might we consider having two storage containers, one zfs and one btrfs)
    • we'll have containers dedicated to databases one for user databases, one for system stuff like ldap, gitea, trac?
