hi,all: I use 15.2.10 ceph cluster with ubuntu 18.04.I create a rbd device and map into a host(ubuntu 18.04 ceph 15.2.10), When i type mkfs.fs -f /dev/rbd0 it is hangs,But it is ok that write data use "rados -p {poolname} put obj myfile". Has anyone encountered this kind of problem? _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
