[lustre-discuss] tune2fs being blocked by MMP

I want to change the ext4 error behaviour from "continue" to panic.

However tune2fs is reporting:

tune2fs: MMP: device currently active while trying to open /dev/mapper/scratch--1--5-scratch_3
MMP error info: last update: Tue Aug  2 15:34:09 2016
node: edi-vf-1-5.ad.cirrus.com device: dm-19
0 edi-vf-1-5:~#

And not changing the value. I have failover setup on this device.

Can anyone help?
