rrdcached plugin: Failed to connect to RRDCached at unix:/run/rrdcached.sock: Unable to connect to ...

aki45 · 16. Dezember 2023

I've got many rrdcached errors like the below after installing omv.

Code

Dec 16 13:42:10 tmaster collectd[702]: rrdcached plugin: Failed to connect to RRDCacheD at unix:/run/rrdcached.sock: Unable to connect to rrdcached: No such >
Dec 16 13:42:10 tmaster collectd[702]: rrdcached plugin: Failed to connect to RRDCacheD at unix:/run/rrdcached.sock: Unable to connect to rrdcached: No such >

To resolve the errors, what I did was as follows.

set timezone on omv web interface.
omv-firstaid (Check RRD database)
disable monitoring and enable monitoring

But still, there are errors.

At the Check RRD database process, I got the following output.

Code

Checking all RRD files. Please wait ...
All RRD database are valid.
ERROR: Command '['monit', 'start', 'rrdcached']' returned non-zero exit status 1.

How can I correct the errors?

Thanks in advance.

Thanks for your reply.

But still the same errors.

What is the output of journalctl -u rrdcached.service

I reinstalled omv6 but still have the same errors.

By the way, I'm quite new to omv, so I don't know well about rrdcached.

What is the effect of the errors?

Just for CPU widget on Dashboard?

Thanks.

After reinstalling, the errors have gone.

I probably got the errors because I removed the system USB too early.

Thank you for your support and attention.

Try running omv-salt deploy run rrdcached

Just a post to say "thank you" as it solved the same issue I had (after having to wait a long time at the screen with nothing moving/printing)

Bash

# omv-salt deploy run rrdcached

[...]

No more errors logs

( Thanks for the project OMV by the way )
