参照网上的解决方法是:
xfs_repair /dev/dm-0
我用上面这个方法确实解决了我的node01节点,但是我们的master节点执行这个命令的时候报错:
xfs_repair: cannot open /dev/dm-0: Device or resource busy
然后我又仔细看报错提示,看到了关键一条信息:
[ 3.852991] XFS (dm-0): Unmount and run xfs_repair
系统提示我,需要先umount,再执行 xfs_repair 命令
所以,需要先umount,但是没有提示需要umount 什么东西,dm-0 是centos-root 的软连接,所以
umount /dev/mapper/centos-root
xfs_repair -v -L /dev/mapper/centos-root
reboot
虚拟机又可以重新使用了
