我的KVM主机在LVM卷上运行VM时遇到了问题.截至昨晚,逻辑卷不再是这样(我无法创建它们的快照,即使我已经好几个月了). @H_403_2@运行任何扫描都会导致找不到任何内容：

[root@apollo ~]# pvscan
No matching physical volumes found

[root@apollo ~]# vgscan
Reading all physical volumes.  This may take a while...
No volume groups found

root@apollo ~]# lvscan
No volume groups found

@H_403_2@如果我尝试从/ etc / lvm / backups / vg0恢复VG conf备份,我会收到以下错误：

[root@apollo ~]# vgcfgrestore -f /etc/lvm/backup/vg0 vg0
Couldn't find device with uuid 20zG25-H8MU-UQPf-u0hD-NftW-ngsC-mG63dt.
Cannot restore Volume Group vg0 with 1 PVs marked as missing.
Restore Failed.

@H_403_2@/ etc / lvm / backups / vg0具有以下物理卷：

physical_volumes {

            pv0 {
                    id = "20zG25-H8MU-UQPf-u0hD-NftW-ngsC-mG63dt"
                    device = "/dev/sda5"    # Hint only

                    status = ["ALLOCATABLE"]
                    flags = []
                    dev_size = 4292870143   # 1.99902 Terabytes
                    pe_start = 384
                    pe_count = 524031       # 1.99902 Terabytes
            }
}

@H_403_2@fdisk -l / dev / sda显示以下内容：

[root@apollo ~]# fdisk -l /dev/sda

@H_403_2@服务器正在运行4磁盘硬盘RAID10,根据megacli和smartd看起来非常健康.

@H_403_2@/ var / log / messages中唯一奇怪的消息是每隔几小时出现的以下信息：

Jun 10 09:41:57 apollo udevd[527]: Failed to create queue file: No space left on device

@H_403_2@输出df -h

[root@apollo ~]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3            1016G  119G  847G  13% /
/dev/sda2             508M   67M  416M  14% /boot

@H_403_2@有没有人有任何想法下一步做什么？除了无法对它们进行快照之外,VM目前都运行良好.

@H_403_2@更新了额外信息
这不是缺少inode：

[root@apollo ~]# df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/sda3            67108864   48066 67060798    1% /
/dev/sda2              32768      47   32721    1% /boot

@H_403_2@pvs,vgs& lvs要么输出任何内容,要么“找不到卷组”.
