Leases on lockspace s3 will expire in one second after this message... > Sep 28 16:20:03 ovirtnode02 sanlock[10993]: 2021-09-28 16:20:03 7690987 > [10993]: s1 check_our_lease warning 71 last_success 7690916 When leases expire, sanlock to terminate the lease owner (.e.g vdsm, qemu). If the owner of the lease cannot be terminated in (~40 seconds) the sanlock must reboot the host. So the host running hosted engine may be rebooted because storage is inaccessible and qemu is stuck on storage. Other hosts may have the same issue they run HA VMs, server as the SPM, or run storage tasks that use a lease. To understand if this is the case, we need complete sanlock.log and vdsm.log from the hosts, when the issue happens. Please file ovirt vdsm bug for this, and attach relevant logs.
