Clusternode/GUI not working

Hi,

i am running a cluster with 3 ceph nodes.
Since a power failure, I had a problem with the system disk and have to do a fsck to get the node start.
Fortunately, the node with all the ceph services came up and work.
I got the services running again but, i have a problem with the cluster/gui -> see the picture.

What can i do to get the cluster respectively the gui to work normal again.
Where can i find the necessary log files for this.



thanks for help
