Xfsdump 无法获取根 inode 的批量统计信息

Xfsdump 无法获取根 inode 的批量统计信息

我用转储从我的 CentOS 服务器进行转储,但是出现此错误,我该如何修复它?

[root@my_server ~]# xfsdump - /dev/vda2
xfsdump: using file dump (drive_simple) strategy
xfsdump: version 3.0.4 (dump format 3.0) - Running single-threaded
xfsdump: unable to determine uuid of fs mounted at /: Inappropriate ioctl for device
xfsdump: level 0 dump of my_server:/
xfsdump: dump date: Tue Jul 21 15:42:16 2020
xfsdump: session id: aeecf825-9dce-477f-b383-549cb7cf980b
xfsdump: session label: ""
xfsdump: ERROR: failed to get bulkstat information for root inode
xfsdump: Dump Status: ERROR

这是系统磁盘列表:

[root@my_server ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda2        16G  3.5G   12G  24% /
tmpfs           939M     0  939M   0% /dev/shm
/dev/vdb1        99G  5.9G   88G   7% /var/my_dir

确保它的类型正确(xfs),然后尝试运行

如果它是扩展* 然后尝试使用倾倒代替軟體系
