Re: libgfapi as non-root

Hi Behrooz,

The error says about "testvol2" where the 'gluster volume info' you provided is on "testvol"

 [2015-03-25 22:50:08.079884] E [glfs-mgmt.c:599:mgmt_getspec_

cbk] 0-glfs-mgmt: failed to fetch volume file (key:testvol2)

Can you please cross-check on this ?

Hello everyone,

 I want to use libgfapi c api in my code. I have installed glusterfs on my host with two bricks and created a volume called 'testvol'; however, in my code 'glfs_init' fails with -1 when I run my program without sudo access. If I run it as root it will connect fine. I saw an email in the mailing list with this solution:

1. add ” option rpc-auth-allow-insecure on” to *.vol file
2. set <volname> server.allow-insecure on
3. stop and start the volume

so I added ” option rpc-auth-allow-insecure on” to every .vol file in /var/lib/glusterd/vols/testvol including (testvol.IP.media-behrooz-Backup-gluster-brick1.vol  testvol-rebalance.vol  trusted-testvol.tcp-fuse.vol
testvol.IP.media-behrooz-Backup-gluster-brick2.vol  testvol.tcp-fuse.vol) as well as /etc/glusterfs/glusterd.vol. And also set testvol server.allow-insecure on and stop and start. Here is the info of my volume:

Volume Name: testvol
Type: Replicate
Volume ID: 3754bf24-d6b0-4af7-a4c9-d2a63c55455c
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: IP:/media/behrooz/Backup/gluster/brick1
Brick2: IP:/media/behrooz/Backup/gluster/brick2
Options Reconfigured:
server.allow-insecure: on
auth.allow: *

But still no luck and here is what I see in my program output:

And I use:
glusterfs 3.6.2 built on Feb  7 2015 06:29:50

Any help or comment is highly appreciated!

Thanks,
