Since yesterday I found a couple VMs with locked disk. I don't know the reason, I suspect some interaction made by our backup system (vprotect, snapshot based), despite it's working for more than a year. I'd give a chance to unlock_entity.sh script, but it reports: CAUTION, this operation may lead to data corruption and should be used with care. Please contact support prior to running this command Do you think I should trust? Is it safe? VMs are in production... My manager is 4.4.4.7-1.el8 (CentOS stream 8), hosts are oVirt Node 4.4.4 TIA, Giulio
