Re: MDS injectargs

[Eugen Block <eblock@xxxxxx>]

Oh, okay... can you run it on a specific host instead of "mds.*"?

I only get the error if I try to run the command on host 1 for host 2:

ceph@host1:~> ceph daemon mds.host2 config show
admin_socket: exception getting command descriptions: [Errno 2] No  
such file or directory
ceph@host1:~> ceph daemon mds.host1 config show | grep mds_cache_size
    "mds_cache_size": "0",
