Yes, I am using multiple hosts and sharings vm.
But this was the nfs server host, so I thought there was no point in

I wouldn't rely on sanlock working properly when accessed both locally and
I'm running another set of 3 hosts with exactly the same
(ext4, lvm, md raid) for months, and I get no error.
The problem isn't errors per se, it's the unpredictable nature of
concurrent, atomic reads and writes to lease sectors. This is also why
I'd not put mirroring or other software raid under the lease storage.

You can ignore this, we're doing it intentionally, we don't care about
but no "check_our_lease corrupt"
I don't know why this happened, but I'd wager it's related to mixing local
and remote i/o to the leases.
