De-containerify uffizi
Closed, MigratedEdits Locked
Actions

Description

uffizi (the main storage backend and objstorage server) should move to the bare metal that currently hosts the louvre hypervisor, removing the containerization layer and giving it all the ram of the host.

on the container :

  • install a kernel, install grub
  • install lvm2, multipath, mdadm
  • pull lvm2, multipath, mdadm config from louvre
  • write /etc/fstab
  • install ifenslave, vlan
  • pull network config (bond, vlan, storage array management) from louvre and adapt to use uffizi ip address
  • pull the hand-installed storage array management tools from /opt on louvre

on the infra:

  • stop workers

on the host:

  • stop the container
  • chroot in the container rootfs and run grub install
  • reboot

I'm not 100% certain about the config of the array management interfaces as the system is going to move to predictable interface names that I'm not quite sure how to predict...

Current config:

5: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether ec:f4:bb:dd:42:22 brd ff:ff:ff:ff:ff:ff
    inet 192.168.254.94/31 scope global eth2
       valid_lft forever preferred_lft forever
    inet6 fe80::eef4:bbff:fedd:4222/64 scope link 
       valid_lft forever preferred_lft forever
6: eth3: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN group default qlen 1000
    link/ether ec:f4:bb:dd:42:23 brd ff:ff:ff:ff:ff:ff
    inet 192.168.254.96/31 scope global eth3
       valid_lft forever preferred_lft forever

Only $DEITY knows if that's going to end up as eno3/4 or enp1s0f2/3??

So, that all happened and uffizi is now bare metal.

multipath-tools-boot needed to be installed to get the proper boot sequencing between mdraid, multipath and lvm. also, typos in /etc/lvm/lvm.conf fixed.

The interfaces showed up as eno3/4 so that got fixed in /etc/network/interfaces as well.

I've confirmed that the dell storage manager works fine.
