What about gluster volume info on both nodes!? Ex.: Volume Name: sambacluster Type: Replicate Volume ID: 4fd0da03-8579-47cc-926b-d7577dac56cf Status: Started Number of Bricks: 1 x 2 = 2 Transport-type: tcp Bricks: Brick1: s4master:/raid5hs/glusterfs/samba Brick2: s4slave:/raid5hs/glusterfs/samba Options Reconfigured: network.ping-timeout: 5 performance.quick-read: on What are telling you your log files? ----------------------------------------------- EDV Daniel M?ller Leitung EDV Tropenklinik Paul-Lechler-Krankenhaus Paul-Lechler-Str. 24 72076 T?bingen Tel.: 07071/206-463, Fax: 07071/206-499 eMail: mueller at tropenklinik.de Internet: www.tropenklinik.de ----------------------------------------------- -----Urspr?ngliche Nachricht----- Von: Bobby Jacob [mailto:bobby.jacob at alshaya.com] Gesendet: Mittwoch, 18.

BUT I am writing through the volume mount-point from the clients. !! NOT directly into the bricks. !! I'm using GlusterFS 3.3.2 with Centos6.4 . !

Hello, this ist he behavior as if you write directly into the glusterd directory/partition and not to the remounted replicating bricks!?

September 2013 07:36 An: gluster-users at gluster.org Betreff: Mounting same replica-volume on multiple clients. ???? HI, I have 2 gluster nodes (GFS01/GFS02) each with a single brick (B01/B01). I have created a simple replica volume with these bricks. Bricks ?? : GFS01/B01 and GFS02/B01. Volume: TestVol I have 2 clients (C01/C02) which will mount this "testvol" for simultaneous read/write. The 2 clients run the same application which is load-balanced, so user request are end to both the client servers which reads/writes data to both the same volume. Mounting the volume on C1?????? :?????????????? mount -t glusterfs -o backupvolfile-server=GFS02 GFS01:/testvol /data Mounting the volume on C2?????? :?????????????? mount -t glusterfs -o backupvolfile-server=GFS01 GFS02:/testvol /data Is this the appropriate way to be followed.? At times, I notice that when I write data through C1-mount point the data is written only to GFS01/B01 and if data is written through C2-mount point the data is written only to GFS02/B01. Please advise. !! Thanks & Regards, Bobby Jacob
