Hi, there is no healing operation, not peer disconnects, no readonly filesystem. Yes, storage is slow and unavailable for 120 seconds, but why, its SSD with 10G, performance is good. > you'd have it's log on qemu's standard output, If you mean /var/log/libvirt/qemu/vm.log there is nothing. I am looking for problem for more than month, tried everything. Can’t find anything. Any more clues or leads?
