在web ui页面查看

pve-sda1lvm卷组已删除

pve-sda1lvm卷组状态为unknown

解决

Web UI 的存储配置是通过 /etc/pve/storage.cfg 文件管理的，删除pve-sda1 相关条目

root@pve:~# cat /etc/pve/storage.cfg
dir: local
	path /var/lib/vz
	content backup,import,iso,vztmpl

lvmthin: local-lvm
	thinpool data
	vgname pve
	content images,rootdir

lvm: pve-sda1
	vgname pve-sda1
	content images,rootdir
	nodes pve
	shared 0

root@pve:~# cp /etc/pve/storage.cfg /etc/pve/storage.cfg.bak
root@pve:~# vim /etc/pve/storage.cfg
dir: local
        path /var/lib/vz
        content backup,import,iso,vztmpl

lvmthin: local-lvm
        thinpool data
        vgname pve
