[PVE-User] ceph could not work with PVE2.1 problem

[Alexandre DERUMIER]

Hi, the ceph/rbd cluster is only available from kvm userspace.

So you can't see it from your host.



if you wan't to use rbd command (why?), you need pass arguments to your command line.

here the proxmox code.
 my $cmd = ['/usr/bin/rbd', '-p', $scfg->{pool}, '-m', $monhost, '-n',
               "client.$scfg->{username}",
               '--keyring', "/etc/pve/priv/ceph/${storeid}.keyring",
               '--auth_supported', $scfg->{authsupported}, $op];

After changing version to pve-test, I can see the "ceph" in the web, 
but the capacity is empty... 
If i use command line to login to the PVE server, how can I check the 
ceph cluster storage in the PVE server by command? such as "df" or 
others command? 

I use "df", but it seems no result. 
# df -h 
Filesystem Size Used Avail Use% Mounted on 
/dev/mapper/pve-root 7.9G 2.0G 5.5G 27% / 
tmpfs 1000M 0 1000M 0% /lib/init/rw 
udev 990M 200K 990M 1% /dev

/dev/sda1 495M 78M 392M 17% /boot 
/dev/fuse 30M 20K 30M 1% /etc/pve 

when i use "rbd ls", there is still the same error. 
# rbd ls

using default settings. 
unable to find any monitors in conf. please specify monitors via -m 
monaddr or -c ceph.conf 
error: couldn't connect to the cluster! 

I had cp the keyring file to the following path. 
# ls /etc/pve/priv/ceph/mycephcluster.keyring 
/etc/pve/priv/ceph/mycephcluster.keyring 

cat the conf file: 
# cat /etc/pve/storage.cfg
