While in the GUI and I select Node -> Physical Disk List, I get the "wait" circle, but nothing after that.

Log shows:

Please advise.

At the same time, none of my graphs are displaying on the Dashboard Page and I get a "Request Error" tag on the display. I don't see anything in the PetaSAN.log about that though.

At first sight,it could be related to the /etc/hosts issue you had...from the host you are connecting the ui to, make sure you are able to ping all other hosts by hostname.

the other thing to check is doing a

ceph osd tree

and make sure all hostnames are listed correctly.

GUI only displays disks from petasan-0 and petasan-3 successfully.

if i understand, when you click the physical disk list, some nodes work, some you get a wait circle.. the node you connect to vi the browser is able to ping all nodes via their host names.

can you send the /opt/petasan/log/PetaSAN.log files on both the node you connect to via browser as well as the node you select and get a wait circle, capturing the logs immediately after getting the problem.  email both files to contact-us at  petasan.org

Can you try the following patch on nodes with issue:

https://drive.google.com/file/d/1xMmkrdYCwM9wdcNGnbUq4hZCXpH_JZuC/view?usp=sharing

apply via

patch  -d / -p1 < handle_ptype_none.patch

we think some partitions may have a missing partition type, maybe created from another os..maybe.

installed the patch on petasan-6.

Now displays the disks as expected. Also getting the following INFO alert:

04/09/2019 12:26:40 INFO     partision rbd0p1 has no ptype.

Excellent.. this seems to fix it 🙂

it seems /dev/rbd0p1  was the issue..it this a partition you mounted yourself ? it will help to know

I am seeing a very similar behavior coming from 2.3.1 > took the upgrade path to 3.3 and still broken when trying to view the physical disk of the nodes.
