[Gluster-users] Need urgent help to downgrade 3.7.12 to 3.7.11

[Lindsay Mathieson]

My 3.7.12 upgrade has rendered my vm cluster unusable and I urgently 
need to downgrade to a working version.


I can't set the op-version back from 30712 to 30710, I get error:

gluster v set all  op-version 30710
volume set: failed: Required op-version (30710) should not be equal or 
lower than current cluster op-version (30712)


If I revert the gluster packages to 3.7.11 then the gluster servcie 
refuses to start.


BTW, current settings are:
