Hmm, I have same output:

conversion of 1.0 gave ret: 0, value: 1.000000
And If I try to mount in servers, I got same problem ...
From Ubuntu machine I can't mount too, can't say is this client
problem or server's ...
The issue is happening from gluster alright, just don't understand why :-(
here is the way to debug it in gdb:

I am extremely sorry to ask you to do this, but I don't know how else I
can gather information :-(

Hello all!
I am new in gluster world, and want to test this "beast" technology.
I created 4 CentOS 7 demo machines with two 50 gb disks in each
machine for bricks. I installed gluster by this simple "howto":
http://www.server-world.info/en/note?os=CentOS_7&p=glusterfs
All goes well, I created volume with "replica 2" options, and use
all 8 bricks. Volume create successfully and I started it:
[root@gluster1 ~]# gluster volume start test
volume start: test: success
[root@gluster1 ~]# gluster volume info
Volume Name: test
Type: Distributed-Replicate
Volume ID: 226592b1-089f-4727-a009-19838078b7e7
Status: Started
Number of Bricks: 4 x 2 = 8
Transport-type: tcp
Bricks:
Brick1: gluster1:/brick1/test
Brick2: gluster1:/brick2/test
Brick3: gluster2:/brick1/test
Brick4: gluster2:/brick2/test
Brick5: gluster3:/brick1/test
Brick6: gluster3:/brick2/test
Brick7: gluster4:/brick1/test
Brick8: gluster4:/brick2/test
Could you let us know which version of gluster are you using?
gluster should have thrown a warning when two bricks are chosen
from same machine for replica pairs.
I am running gluster 3.6.1
[root@gluster1 ~]# glusterfsd --version
glusterfs 3.6.1 built on Nov 7 2014 15:16:38
But, when I try to mount volume in CentOS 7 machine I got error:
[root@gclient ~]# mount -t glusterfs gluster1:/test /mnt
WARNING: getfattr not found, certain checks will be skipped..
Error in log file:
[xlator.c:425:xlator_init] 0-fuse: Initialization of volume
'fuse' failed, review your volfile again
Could you please send the complete log.
Complete record when I try to mount from /var/log/glusterfs/mnt.log:
[2014-11-22 16:03:51.728816] I [MSGID: 100030]

attribute-timeout seems to be the problem as per the log above.
I tried testing this and things seem to be fine. May be I should know
the behavior of the program on your system.
Could you compile the following c program and tell me the output:
==========================================
#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
static int
_gf_string2double (const char *str, double *n)
{
double value = 0.0;
char *tail = NULL;
int old_errno = 0;
if (str == NULL || n == NULL) {
errno = EINVAL;
return -1;
}
old_errno = errno;
errno = 0;
value = strtod (str, &tail);
if (str == tail)
errno = EINVAL;
if (errno == ERANGE || errno == EINVAL)
return -1;
if (errno == 0)
errno = old_errno;
if (tail[0] != '\0')
return -1;
*n = value;
return 0;
}
int
main (int argc, char **argv)
{
double value = 0.0;
int ret = 0;
ret = _gf_string2double ("1.0", &value);
if (ret < 0)
printf ("conversion of 1.0 failed with %s",
strerror(errno));
else
printf ("conversion of 1.0 gave ret: %d, value: %lf",
ret, value);
}
==========================================
Save this into 'file.c'
# gcc file.c
# ./a.out
It should print the following output:
conversion of 1.0 gave ret: 0, value: 1.000000.
Could you let me know what is the output on your machine?

Would be grateful for any help!
