Ceph » mgr » Dashboard

Create new pools and a CephFS filesystem:

$ ceph osd pool create cephfs.b.data 8
$ ceph osd pool application enable cephfs.b.data cephfs
$ ceph osd pool create cephfs.b.meta 8
$ ceph osd pool application enable cephfs.b.meta cephfs

$ ceph fs flag set enable_multiple true
$ ceph fs new b cephfs.b.meta cephfs.b.data

• UI crashes because of accessing non-existing data:

Go to the dashboard and select the 'b' filesystem in the filesystem table.

• The 'Performance Details' tab is shown either no GrafanaID is set

and no graphs could be displayed. In such a case the tab shouldn't be displayed.

• The clients tab crashes when selecting filesystem 'b'.
