Subject: [linux-lvm] lvm snapshot cannot be removed with the error "Failed to refresh without snapshot"
Date: Wed, 19 Jun 2019 03:26:33 -0600	[thread overview]
Message-ID: <5D09FFC9020000F90006D3D6@prv1-mh.provo.novell.com> (raw)

Hello List,

Our user is using lvm2-2.02.180, he attempted to remove a snapshot LV, but failed with the below error,
lvremove /dev/evg00/snap_var
  WARNING: Failed to connect to lvmetad. Falling back to device scanning.
Do you really want to remove active logical volume evg00/snap_var? [y/n]: y
  device-mapper: reload ioctl on  (254:36) failed: Invalid argument
  Failed to refresh var without snapshot.

But I can not reproduce in local, how do I find the root cause behind this problem?
I also can see one related error message in /var/log/messages
