Re: Problems with ceph command - Octupus - Ubuntu 16.04

[Eugen Block <eblock@xxxxxx>]

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.
