Originally, I thought this feature would be enabled on all pools, but instead it requires that the <tt>multimount</tt> property be set on the pool before it is active.</p> <p>Similar to how mount_utils_ldiskfs.c enables the <tt>mmp</tt> feature if failover is enabled on the pool, mount_utils_zfs.c should set the <tt>multimount</tt> property. I believe that this property would be ignored on ZFS 0.6.5 pools, so it is not harmful to always set it for Lustre filesystems.</p> LU-9772
