Ali told me that the rpm for Ganesha's CephFS FSAL(driver),
nfs-ganesha-ceph v2.5.0.1 (28th June) available at download.ceph.com,
was built using libcephfs2 of Ceph luminous release v12.0.3.

AFAIK Ali's working on building latest nfs-ganesha, and nfs-ganesha-ceph FSAL
(v2.5.0.4) rpms and debs using libcephfs2 in latest luminous release, 12.1.1.
You can expect them to be at download.ceph.com/nfs-ganesha sometime soon.

I didn't know about that repo, and compiled ganesha myself. The

the libcephfs version.
After recompiling ganesha with a kraken libcephfs instead of a jewel 
version both errors went away.


I'm sure using a compiled Version from the repo you mention would have

2017-07-18 Thread David 
You mentioned the Kernel client works but the Fuse mount would be a better
test in relation to the Ganesha FSAL.

The following config didn't give me the error you describe in 1) but I'm
mounting on the client with NFSv4, not sure about 2), is that dm-nfs?

EXPORT
{
Export_ID = 1;
Path = "/";
Pseudo = "/";
Access_Type = RW;
Squash = No_Root_Squash;
SecType = "none";
Protocols = "3", "4";
Transports = "TCP";

FSAL {
Name = CEPH;
}
}

Hi,


> Change Pseudo to something like /mypseudofolder

I tried this, without success, but I managed to get something working with 
version 2.5.

I can mount the NFS export now, however 2 problems remain:

1. The root directory of the mount-point looks empty (ls shows no files), 
however directories
   and files can be accessed, and ls works in subdirectories.

2. I can't create devices in the nfs mount, not sure if ganesha supports this 
with other backends.

Hi,

Not sure if using the root path in Pseudo is valid.

Change Pseudo to something like /mypseudofolder

And see if that solves the problem.

[ceph-users] Problems getting nfs-ganesha with cephfs backend to work.

2017-07-17 Thread Micha Krause 

Hi,

im trying to get nfs-ganesha to work with ceph as the FSAL Backend.

Um using Version 2.4.5, this is my ganeasha.conf:

EXPORT
{
Export_ID=1;
Path = /;
Pseudo = /;
Access_Type = RW;
Protocols = 3;
Transports = TCP;
FSAL {
Name = CEPH;
User_Id = "test-cephfs";
Secret_Access_Key = "***";
}
CLIENT {
Clients = client-fqdn;
Access_Type = RO;
}
}

Here are some loglines from ganeshea indicating that there is a problem:

I have no problems mounting cephfs with the kernel-client on this machine, 
using the same authentication data.


Has anyone gotten this to work, and maybe could give me a hint on what I'm 
doing wrong?
