[Gluster-users] Issue enabling use-compound-fops with gfapi
Hi list, on a dev system I'm testing some options that are supposed to give improved performance, I'm running ovirt with gfapi enabled with gluster 3.12.13 and when I set "cluster.use-compound-fops" to "on" every VMs are paused due to a storage IO error while the file system continue to be accessible through fuse client (only gfapi application stop working). In the qemu log file I could see these gluster related messages: 2018-09-14T11:49:37.020942Z qemu-kvm: terminating on signal 15 from pid 1513 (/usr/sbin/libvirtd) 2018-09-14T11:49:42.766431Z qemu-kvm: Failed to flush the L2 table cache: Input/output error 2018-09-14T11:49:44.766853Z qemu-kvm: Failed to flush the refcount block cache: Input/output error [2018-09-14 11:49:44.869112] E [MSGID: 108006] [afr-common.c:5118:__afr_handle_child_down_event] 0-vm-images-repo-demo-replicate-1: All subvolumes are down.

There is something else to configure or this is a bug? Greetings, ??? Paolo
