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

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. 2017-05-08 9:39 GMT+02:00 Yaniv Kaul <ykaul(a)redhat.com&gt;: > > On Sun, May 7, 2017 at 1:27 PM, Stefano Bovina <bovy89(a)gmail.com&gt; wrote: > >> Sense data are 0x0/0x0/0x0 > > > Interesting - first time I'm seeing 0/0/0.
