[Gluster-users] Strange behaviour glusterd 3.1

Wed Mar 9 10:30:14 UTC 2011

/mnt/glusterfs ist he mount point of the client where the samba-vol (backend:/glusterfs/export) is mounted on.
So it should work. And it did work until last week.

Greetings
Daniel

Directly editing the files on backend is not supported. Most of the editors delete the original file and create a new-one when you edit a file.
So the extended attributes that are stored on the old-file are gone.

Both server running. I edit the file on one node1-server (in /mnt/glusterfs/) changed the content, saved the file. Ssh to the node2-server there still old content. Did " find /mnt/glusterfs -print0 | xargs --null stat >/dev/null", still the same old content.
Need to restart both servers the the new content is written to node2-server.
And this equal behavior on both servers.
A few days ago all was ok.

"But after vim one.txt and changing the content of that file on one node.", what exactly do you mean by this?. Did you edit the file on backend?. (or) Brought one server down and after editing brought the second server back up?.

Dear all,

after some weeks of testing gluster the replication of my two nodes stopped
working the way it used to be.

My version:
glusterfs --version

[root at ctdb2 test]# gluster volume info

Volume Name: samba-vol

Brick2: 192.168.132.57:/glusterfs/export
Options Reconfigured:
network.ping-timeout: 5

Now my mount point for the client is /mnt/glusterfs in fstab:
192.168.132.57:/samba-vol  /mnt/glusterfs  glusterfs  defaults  0  0

Commandline mount succeeds with:

glusterfs#192.168.132.57:/samba-vol on /mnt/glusterfs type fuse
(rw,allow_other,default_permissions,max_read=131072)

Now glusterd worked for many weeks. But now when I create a file (ex:
one.txt) in /mnt/glusterfs/ the file is replicated to the other node well.
But after vim one.txt and changing the content of that file on one node. The
changes are not replicated to the other node
Until I restart both nodes.
I did made a " find /mnt/glusterfs -print0 | xargs --null stat >/dev/null"
with no success.
Any Idea???

Greetings Daniel
