奧地利維也納，2018年12月4日，proxmox官方正式發佈PVE5.3版本。
Proxmox Server Solutions GmbH today unveiled Proxmox VE 5.3, its latest open-source server virtualization management platform. Proxmox VE is based on Debian Stretch 9.6 with a modified Linux Kernel 4.15. Ceph Storage has been updated to version 12.2.8 (Luminous LTS, stable), and is packaged by Proxmox.
proxmox公司發佈最新的開源虛擬化管理平臺PVE5.2.PVE基於流行的linux發行版Debian Stretch 9.6，內核版本4.15.去中心化存儲ceph已經更新到Luminous 12.2.8版本。該版本由proxmox重新封裝。
Proxmox VE and CephFS
Proxmox VE 5.3 now includes CephFS in its web-based management interface thus expanding its comprehensive list of already supported file and block storage types. CephFS is a distributed, POSIX-compliant file system and builds on the Ceph cluster. Like Ceph RBD (Rados Block Device), which is already integrated into Proxmox VE, CephFS now serves as an alternative interface to the Ceph storage. For CephFS Proxmox allows storing VZDump backup files, ISO images, and container templates. The distributed file system CephFS eliminates the need for external file storage such as NFS or Samba and thus helps reducing hardware cost and simplifies management.
PVE5.3 默認包含Cephfs,可以直接用web界面進行配置和管理（注：pve5.2版本用 pveceph install安裝，用命令行初始化pveceph init --network網絡).cephfs支持文件及塊存儲。cephfs是分佈式的、兼容POSIX、去中心化的集羣。cephfs作爲存儲服務接口，可以存儲虛擬機備份文件、ISO鏡像（注：操作系統鏡像共享可以在任意節點進行讀取，不過把這些不使用頻率低的ISO放在ceph存儲，似乎有點浪費資源，譯者本人一般使用獨立的低速NFS來存儲）、容器模板等。cephFS可以完全取代傳統的外掛存儲如NFS、Samba等等，降低固定資產投入及簡化架構和管理。
The CephFS file system can be created and configured with just a few clicks in the Proxmox VE management interface. To deploy CephFS users need a working Ceph storage cluster and a Ceph Metadata Server (MDS) node, which can also be created in the Proxmox VE interface. The MDS daemon separates metadata and data from each other and stores them in the Ceph file system. At least one MDS is needed, but its recommended to deploy multiple MDS nodes to improve high availability and avoid SPOF. If several MDS nodes are created only one will be marked as ‘active’ while the others stay ‘passive’ until they are needed in case of failure of the active one.
在proxmox VE web管理界面，點幾下鼠標就能完成文件系統的創建和配置（譯者注：以前的版本是在命令行完成，直到創建監視器）。以web管理界面創建ceph的元數據及實際數據存儲（譯者注：創建OSD後，用fdisk命令可以看到物理磁盤被分割成兩個分區，大小爲100M的分區爲元數據MDS），守護進程MDS把元數據跟實際數據分離（不吃大鍋飯，提高效率）。在一個ceph集羣中，至少需要一個元數據服務器，爲了保證可靠性，建議使用多個MDS。雖然有多個元數據服務器，但正常情況下，只有一個元數據服務器處於活躍狀態，如果管事的元數據服務器故障，其它服務器選舉新的一個來接替。
補充：升級辦法
1、PVE web界面升級
自動彈出窗口，輸入字母“y"繼續。
2、命令行方式：
登錄沒一個節點，執行apt-get update && apt-get upgrade -y
升級完畢，所需服務自動重啓，無需手動重啓操作系統。
