[ovirt-users] High latency on storage domains and sanlock renewal error

[Stefano Bovina]

Yes,
this configuration is the one suggested by EMC for EL7.

By the way,
"The parameters rr_min_io vs. rr_min_io_rq mean the same thing but are used
for device-mapper-multipath on differing kernel versions." and rr_min_io_rq
default value is 1, rr_min_io default value is 1000, so it should be fine.
