[ceph-users] Re: Problems with ceph command - Octupus - Ubuntu 16.04

Tue, 20 Oct 2020 06:35:59 -0700

Your 'cephadm ls' output was only from one node, I assumed you just bootstrapped the first node.
The 'cephadm logs' command should provide pager-output so you can scroll or search for a specific date. 


I'm not sure what caused this but "error on write" is bad. As I  
already wrote check the filesystems on your nodes, dmesg etc. It seems  
as if two of your MONs are down which would make your cluster  
unavailable (no quorum). Is mon3 up and running? Bringing back one of  
the other two MONs would bring the cluster back up.

From MON1, dmesg I get this:

Subject: Re: [ceph-users] Re: Problems with ceph command - Octupus -  
Ubuntu 16.04


I have 3 MON, I don't know why it's showing only one.

root@osswrkprbe001:~# ceph --connect-timeout 60 status
Cluster connection interrupted or timed out


cephadm logs --name mon.osswrkprbe001 --> Is there any way to go to  
a specific date? Because it stars from Oct 4. I want to check from  
Oct 16 and ahead. I suspect that something happened that day.



Also, I don't know how to troubleshoot this. I did the same  
(./cephadm logs --name mon.osswrkprbe002) in the second MON but it  
starts the logs from Sep 30. I would need to check Oct 16 also.


I would appreciate if you can help me with the troubleshooting.

Thank you.

Your mon container seems up and running, have you tried restarting it?
You just have one mon, is that correct? Do you see anything in the logs?

cephadm logs --name mon.osswrkprbe001

How long do you wait until you hit CTRL-C? There's a
connection-timeout option for ceph commands, maybe try a higher timeout?

ceph --connect-timeout 60 status

Is the node hosting the mon showing any issues in dmesg, df -h, syslog, etc.?

Regards,
Eugen

Hello


I'm facing an issue with ceph. I cannot run any ceph command. It
literally hangs. I need to hit CTRL-C to get this:




^CCluster connection interrupted or timed out




This is on Ubuntu 16.04. Also, I use Graphana with Prometheus to get
information from the cluster, but now there is no data to graph. Any
clue?
