proxmox logo gradToday, the Proxmox VE team have released a new version of Proxmox, incrementing the major version to 5.0!

The new version packs in a raft of new features, the headline being the new Replicated Storage feature which enables batch style synchronisation of local storage volumes across servers.

You can download the ISO from https://www.proxmox.com/en/downloads/item/proxmox-ve-5-0-iso-installer

Highlights of the 5.0 release:

  • Based on Debian Stretch 9.0
  • Kernel 4.10.15
  • QEMU 2.9
  • LXC: update to 2.0.8
  • New asynchronous Storage Replication feature (needs ZFS, technology preview)
  • New/updated LXC templates (Debian, Ubuntu, CentOS, Fedora, OpenSUSE, Arch Linux, Gentoo and Alpine)
  • Updated/improved noVNC console]
  • Ceph v12.1.0 Luminous (technology preview), packaged by Proxmox
  • Live migration with local storage
  • GUI improvements
    • USB und Host PCI address visibility
    • improved bulk and filtering options
  • Improved installation ISO
  • Importing Qemu/KVM_Virtual_Machines#_importing_virtual_machines_from_foreign_hypervisors
  • Improved reference documentation with screenshots
  • Countless bug fixes and package updates

Upgrade

Before updating, make sure all your VM’s have been stopped, both LXC and KVM. Ensure you have the required repository entries for apt. You’ll either need a valid license key or to add the less stable pve-no-subscription repository.

Update your apt for Debian, edit /etc/apt/sources.list and replace it with:

deb http://ftp.at.debian.org/debian stretch main contrib

# security updates
deb http://security.debian.org stretch/updates main contrib

And your Proxmox repository source /etc/apt/sources.list.d/pve-enterprise.list to the below. See Proxmox 3.1 package/ updates manager (this also works for version 5.x) for more information.

deb https://enterprise.proxmox.com/debian/pve stretch pve-enterprise

Run the below commands on each server in your cluster.

apt-get update
apt-get dist-upgrade

Restart all Proxmox servers to complete the installation.

proxmox logo gradThe Proxmox VE team have released a new BETA version of their 5.0 branch to the public.

Proxmox 5.0 beta 1 was released recently, and now the team have released the 2nd beta fixing numerous bugs.

  • Based on Debian Stretch
  • Kernel 4.10
  • Updated qemu 2.9 that supports nested virtualization
  • New Ceph Luminous (12) which is the next LTS.

You can download the ISO from their download site and install it onto a new machine. You can also upgrade an existing Proxmox 4.x release to the new 5.0 release following these instructions.

It’s worth noting that the Proxmox team state that any BETA version of release 5.0 will be upgradeable to the full 5.0 when it’s available through apt.

As this is a BETA version, it’s not recommended in a production environment and should only be used for testing.

A New Version Of Ceph Has Been Released, Ceph Jewel

Category : Tech News

Get Social!

ceph-logoThe latest version of Ceph has been released codenamed Jewel with version number 10.2.0. Ceph Jewel has been released as a long term support (LTS) version and will be retired in November 2017.

The Ceph Jewel release marks the first stable release of CephFS. Whilst some have been using CephFS for some time, this is the first release it’s officially marked as stable and production ready.

Various other improvements have been made with the Jewel release:

  • CephFS:
    • This is the first release in which CephFS is declared stable! Several features are disabled by default, including snapshots and multiple active MDS servers.
    • The repair and disaster recovery tools are now feature-complete.
    • A new cephfs-volume-manager module is included that provides a high-level interface for creating “shares” for OpenStack Manila and similar projects.
    • There is now experimental support for multiple CephFS file systems within a single cluster.
  • RGW:
    • The multisite feature has been almost completely rearchitected and rewritten to support any number of clusters/sites, bidirectional fail-over, and active/active configurations.
    • You can now access radosgw buckets via NFS (experimental).
    • The AWS4 authentication protocol is now supported.
    • There is now support for S3 request payer buckets.
    • The new multitenancy infrastructure improves compatibility with Swift, which provides a separate container namespace for each user/tenant.
    • The OpenStack Keystone v3 API is now supported. There are a range of other small Swift API features and compatibility improvements as well, including bulk delete and SLO (static large objects).
  • RBD:
    • There is new support for mirroring (asynchronous replication) of RBD images across clusters. This is implemented as a per-RBD image journal that can be streamed across a WAN to another site, and a new rbd-mirror daemon that performs the cross-cluster replication.
    • The exclusive-lock, object-map, fast-diff, and journaling features can be enabled or disabled dynamically. The deep-flatten features can be disabled dynamically but not re-enabled.
    • The RBD CLI has been rewritten to provide command-specific help and full bash completion support.
    • RBD snapshots can now be renamed.
  • RADOS:
    • BlueStore, a new OSD backend, is included as an experimental feature. The plan is for it to become the default backend in the K or L release.
    • The OSD now persists scrub results and provides a librados API to query results in detail.
    • We have revised our documentation to recommend against using ext4 as the underlying filesystem for Ceph OSD daemons due to problems supporting our long object name handling.

You can download the ISO from their download site and install it onto a new machine. Unfortunately, because it’s still a BETA product there is no upgrade path from 3.4. I’d expect this to change in the near future.

It’s worth noting, however, that the website states that any BETA version of release 4.0 will be upgradeable to the full 4.0 when it’s available.
