Re: NFS Ganesha fails to export a volume

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

 



I am surprised too that it wasn't caught earlier.

Steps:

1. Clone the gluster repo

2. Compile  the source https://docs.gluster.org/en/latest/Developer-guide/Building-GlusterFS/

3. Make the changes (in a different branch if you prefer), compile again and install

4.  Test it out:

[root@linuxpad glusterfs]#  gluster v create testvol  127.0.0.2:/home/ravi/bricks/brick{1..2} force
volume create: testvol: success: please start the volume to access data
[root@linuxpad glusterfs]#
[root@linuxpad glusterfs]# gluster v start testvol
volume start: testvol: success
[root@linuxpad glusterfs]#
[root@linuxpad glusterfs]# gluster v set testvol ganesha.enable on
volume set: failed: The option nfs-ganesha should be enabled before setting ganesha.enable.
[root@linuxpad glusterfs]#

I just tried the change and it looks like some new error shows up. Not too familiar with these settings; I will need to debug further.

Thanks,

Ravi

I can try to help with the testing (I'm quite new to that).
Can someone share documentation of that process ?

yet we have another problem -> ganesha is deployed with ocf:heartbeat:portblock which supports only IPTABLES, while EL8 uses NFTABLES ...

Hello All,

did anyone get a chance to look at https://github.com/gluster/glusterfs/issues/1778 ?
A look at 
https://review.gluster.org/#/c/glusterfs/+/23648/4/xlators/mgmt/glusterd/src/glusterd-op-sm.c@1117 
seems to indicate this could be due to a typo error. Do you have a 
source install where you can apply this simple diff and see if it fixes 
the issue?
I think you are right - I seem to have introduced it as part of https://github.com/gluster/glusterfs/commit/e081ac683b6a5bda54891318fa1e3ffac981e553 - my bad.

However, it was merged ~1 year ago, and no one has complained thus far... :-/
1. Is no one using NFS Ganesha? 
2. We are lacking tests for NFS Ganesha - code coverage indicates this path is not covered.

Y.

It's really strange that NFS Ganesha has ever passed the tests.
How do we test NFS Ganesha exporting ?
