Screenshots

I see a lot of error logs from ReGaHss:

-0 local0.warn ReGaHss: WARNING: XMLRPC 'getValue': rpcClient.isFault() failed (url: xmlrpc_bin://127.0.0.1:32001, params: {"xxxxx:1","LEVEL"}, result: [faultCode:-2
-0 local0.err ReGaHss: ERROR: XMLRPC 'getValue' call failed (interface: 1007, params: {"xxx:1","LEVEL"}) [CallGetValue():iseXmlRpc.cpp:1435]

System information:

• RaspberryMatic Version: 3.55.10.20210213
• Used Hardware: CCU on x86
• Used HomeMatic RF-Module: HM-MOD-RPI-PCB/HB-RF-USB@usb-0000:00:14.0-6

Additional context

I restored an old backup but this did not help either.

Hmm, that's actually a hard one. Are the HomeMatic devices still visible in the WebUI or are they completely deleted there?

The error in your logs just state that communication with these devices is not possible. What about rfd process? Is it running? Also make sure multimacd and /dev/eq3loop is there.

I am checking if this is #903 (comment) back. Trying to remember where I added the mount option in Raspberrymatic ;-)

The symptomps are the same. Yes, rfd is running.

--- Update 1
When I moved to the official chart this weekend I missed the circumvention for the rfd to work on GlusterFS. Re-adding...

[angelnu]

It was indeed the inode problem @jens-maus - and after you run into it the CCU config is messed up and a restore from backup is needed.

Any place to documment this so others might find it (maybe my me in the future :-) )?

We can close this - I will do a PR with some changes I did to the Helm chart during this activity.

Feel free to add some "Known Limitations" section to the wiki documentation if you like and document it there.
