Re: NFS-ganesha with RGW

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi, thanks for the quick reply. As for 1. I mentioned that i'm running ubuntu 16.04, kernel 4.4.0-121 - as it seems the platform package(nfs-ganesha-ceph) does not include the rgw fsal.

2. Nfsd was running - after rebooting i managed to get ganesha to bind, rpcbind is running, though i still can't mount the rgw due to timeouts. I suspect my conf might be wrong, but i'm not sure how to make sure it is. I've set up my ganesha.conf with the FSAL and RGW block - do i need anything else?

EXPORT
{
     Export_ID=1;
     Path = "/";
     Pseudo = "/";
     Access_Type = RW;
     SecType = "sys";
     NFS_Protocols = 4;
     Transport_Protocols = TCP;

     # optional, permit unsquashed access by client "root" user
     #Squash = No_Root_Squash;

    FSAL {
             Name = RGW;
             User_Id = <user name for the rgw - associated with the access key/secret>;
             Access_Key_Id = "<access key>";
             Secret_Access_Key = "<secret>";
     }

    RGW {
    cluster = "ceph";
    name = "client.radosgw.radosgw-s2";
        ceph_conf = "/etc/ceph/ceph.conf";
        init_args = "-d --debug-rgw=16";
    }
}

Hi Josef,

1. You do need the Ganesha fsal driver to be present;  I don't know
your platform and os version, so I couldn't look up what packages you
might need to install (or if the platform package does not build the
RGW fsal)
2. The most common reason for ganesha.nfsd to fail to bind to a port
is that a Linux kernel nfsd is already running--can you make sure
that's not the case;  meanwhile you -do- need rpcbind to be running

Hi everyone, i'm currently trying to set up a NFS-ganesha instance that
mounts a RGW storage, however i'm not succesful in this. I'm running Ceph
Luminous 12.2.4 and ubuntu 16.04. I tried compiling ganesha from
source(latest version), however i didn't manage to get the mount running
with that, as ganesha refused to bind to the ipv6 interface - i assume this
is a ganesha issue, but i didn't find any relevant info on what might cause
this - my network setup should allow for that. Then i installed ganesha-2.6
from the official repos, set up the config for RGW as per the official howto
http://docs.ceph.com/docs/master/radosgw/nfs/, but i'm getting:
Could not dlopen module:/usr/lib/x86_64-linux-gnu/ganesha/libfsalrgw.so
Error:/usr/lib/x86_64-linux-gnu/ganesha/libfsalrgw.so: cannot open shared
object file: No such file or directory
and lo and behold, the libfsalrgw.so isn't present in the folder. I
installed the nfs-ganesha and nfs-ganesha-fsal packages. I tried googling
around, but i didn't find any relevant info or walkthroughs for this setup,
so i'm asking - was anyone succesful in setting this up? I can see that even
the redhat solution is still in progress, so i'm not sure if this even
works. Thanks for any help,

Josef
