The cenario is: Host: Centos 7.6 Libvirt 4.5 Ceph 13.2.4 I follow the following steps to increase the disk (ex: disk 10Gb to 20Gb): # rbd resize --size 20480 mypool/vm_test # virsh blockresize --domain vm_test --path vda --size 20G But after this steps, the disk in VM continue with original size. For apply the change, is necessary reboot VM. If I use local datastore instead Ceph, the VM recognize new size imediatally. Does anyone have this? Is this expected? _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
