ceph: 14.2.x kernel: 4.15 In cephfs, due to the need for cache consistency, When a client is executing buffer IO, another client will hang when reading and writing the same file It seems that lazyio can solve this problem, lazyio allows multiple clients to execute buffer IO at the same time(relax consistency), But I am not sure how to enable lazyio under the kernel mount, the test found that the "client_force_lazyio" parameter does not work My final requirement is to use lazyio to implement multiple clients to read and write the same file(buffer IO mode) Can someone explain how to enable lazyio under kcephfs, thanks _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
