Hello, We have an issue when writing to ceph. From time to time the write operation seems to hang for a few seconds. We've seen the https://bugzilla.redhat.com/show_bug.cgi?id=1389503, and there it is said that when the qemu process would reach the max open files limit, then "the guest OS should be paused". Is this the case for the entire guest OS, or it is only for the given write operation? In our case we have observed situations when different processes in the same VM are accessing different mountpoints (all of them on ceph) and some will fail while others does not. Kind regards, Laszlo _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
