Proxmox Backup Server增量备份魔方云
PBS备份PVE很好用,对于PVE以外的系统,PBS给了proxmox-backup-client这个客户端,在Debian/Ubuntu下有官方维护的包,但CentOS下没有。github上有个大神封装了RHEL8和RHEL9的客户端,也支持RockyLinux8 / RockyLinux9 / AlmaLinux8 / AlmaLinux 9。

我们在近期运营中,PVE节点开通的VM客户反馈了一些异常情况:
1、PVE VM启用firewall/ macfilter/ ipfilter,ipset rules正确,但没有网络,重装系统/ 防火墙关闭也无法恢复;但在PVE VM网卡停用firewall网络即恢复。
2、PVE VM网络正常,但firewall rules不生效。
3、pve-firewall出现错误: status update error: iptables_restore_cmdlist: Try `iptables-restore -h' or 'iptables-restore --help' for more information.
巡检中发现PVE的zfs-raidz2坏了一个盘,查询显示:
~# zpool status rpool
pool: rpool

Sufficient replicas exist for the pool to continue functioning in a

Proxmox+VE用于公有云、VPS的可靠性得到了很多同行长期的验证认可,整个生态环境也满足我的需求,所需功能也基本都能满足,所以我开始用PVE了。我考虑用本地存储,如果是用智简魔方的公有云平台,一般情况只有硬卡RAID10是最好方案;但PVE出现了多个方案,我挑了几个,但很犹豫哪个最合适我:ZFS-RAID-Z2、ZFS-RAID-Z3、ZFS-RAID10,以及硬卡RAID10。
