[Gluster-users] Strange issu concerning glusterfs 3.5.1 on centos 6.5

[Daniel Müller]

Dear all,

there is a strange issue centos6.5 and glusterfs 3.5.1:

 glusterd -V
glusterfs 3.5.1 built on Jun 24 2014 15:09:41

I try to set up a replicated 2 brick vol on two centos 6.5 server.
I can probe well and my nodes are reporting no errors:
 
[root at centclust1 mnt]# gluster peer status
Number of Peers: 1

Hostname: centclust2
Uuid: 4f15e9bd-9b5a-435b-83d2-4ed202c66b11
State: Peer in Cluster (Connected)

[root at centclust2 sicherung]# gluster peer status
Number of Peers: 1

Hostname: 172.17.2.30
Uuid: 99fe6a2c-df7e-4475-a7bc-a35abba620fb
State: Peer in Cluster (Connected)

Now I set up a replicating VOl on an XFS-Disk: /dev/sdb1 on /sicherung type
xfs (rw)

gluster volume create smbbackup replica 2 transport tcp
centclust1.tplk.loc:/sicherung/bu  centclust2.tplk.loc:/sicherung/bu

gluster volume smbbackup status reports ok:

[root at centclust1 mnt]# gluster volume status smbbackup

Task Status of Volume smbbackup
----------------------------------------------------------------------------

There are no active volume tasks

I mounted the vol on both servers with:

mount -t glusterfs centclust1.tplk.loc:/smbbackup  /mnt/sicherung -o acl
mount -t glusterfs centclust2.tplk.loc:/smbbackup  /mnt/sicherung -o acl

But when I write in /mnt/sicherung the files are not replicated to the other
node in anyway!??

They rest on the local server in /mnt/sicherung and /sicherung/bu
On each node separate:#
[root at centclust1 sicherung]# pwd
/mnt/sicherung

[root at centclust1 sicherung]# touch test.txt
[root at centclust1 sicherung]# ls
test.txt
[root at centclust2 sicherung]# pwd
/mnt/sicherung
[root at centclust2 sicherung]# ls
more.txt
[root at centclust1 sicherung]# ls -la /sicherung/bu
insgesamt 0
