Dashboard details section is not working

After recovering my cluster from a failure from a storage size mis-configuration, the dashboard does not display statistics on the lower half with the following error:

Firefox can’t establish a connection to the server at 10.0.20.4:3000.

On all three nodes, I found the following output:

 

root@peta-san-01:~# ceph-disk list
/dev/rbd0 other, unknown
/dev/rbd1 other, unknown
/dev/rbd2 other, unknown
/dev/rbd3 other, unknown
/dev/rbd4 other, unknown
/dev/sda :
/dev/sda1 other, ext4, mounted on /boot
/dev/sda2 other, ext4, mounted on /
/dev/sda3 other, ext4, mounted on /var/lib/ceph
/dev/sda4 other, ext4, mounted on /opt/petasan/config
/dev/sdb :
/dev/sdb1 ceph data, active, cluster peta-san-01, osd.1, block /dev/sdb2
/dev/sdb2 ceph block, for /dev/sdb1
/dev/sr0 other, unknown
root@peta-san-01:~#

Would be necessary to delete the indicated rbdx device and if so, how?

 

Thank-you

The service should start automatically, if not on 10.0.20.4 do:

/opt/petasan/scripts/stats-setup.sh
/opt/petasan/scripts/stats-start.sh

Thanks, that did the trick.

root@peta-san-03:~# /opt/petasan/scripts/stats-setup.sh
root@peta-san-03:~# /opt/petasan/scripts/stats-start.sh
volume set: success
root@peta-san-03:~#

 

I had done a reboot on each of the three nodes and that did not resolve the matter. I had done a manual connection to the affected node and was refused:

root@peta-san-03:~# telnet 10.0.20.4 3000
Trying 10.0.20.4...
telnet: Unable to connect to remote host: Connection refused
root@peta-san-03:~#

 

This manual start though helped.

Thanks as always
