Right now I have two volumes, 'vol_test' and 'vol_nested'. 'vol_test' is mounted at /vol_test, and 'vol_nested' is mounted at /vol_test/vol_nested.
If I create a snapshot for 'vol_test', say 'snap-1', then the directory /vol_test/.snapshot/snap-1/vol_nested also shows up.
However, accessing it will throw the following error:
ls: reading directory .: Input/output error
It is very reasonable to not allow traversing nested junction point within a snapshot. But I wonder in this case why it is still shown there? Is there any way to configure the vserver/volume so that such junction points won't show up in the parent volume's snapshot?
