ubuntu – 从快照创建了一个EBS卷,但是无法挂载它？

fdisk -l显示音量,因此它看起来像是附加的,但是当我按照这些步骤操作时

echo "/dev/xvdg /vol2 xfs noatime 0 0" | sudo tee -a /etc/fstab
sudo mkdir /vol2
sudo mount /vol2

我收到了错误

mount: wrong fs type,bad option,bad superblock on /dev/xvdg,missing codepage or helper program,or other error
     In some cases useful info is found in syslog - try
     dmesg | tail  or so

当我检查dmesg时,我看到了

XFS: Filesystem xvdg has duplicate UUID - can't mount

我该怎么办？

无需安装UUID(短期解决方案)：

mount -o nouuid DEVICE MOUNT_POINT

或者为设备生成新的UUID,然后正常挂载：

xfs_admin -U generate DEVICE

(顺便说一句谷歌的结果.XFS Filesystem has duplicate UUID problem)
