[Gluster-users] Réplication failed again...

[Julien Groselle]

Hello,

I'm back with my replication issues ! :(
I can't understand why i replicate 3To but no more...

We have 2 servers with two storage array, and i installed glusterFS to make
replication in between this server...
As far as i understand, there are just one command to use ?

toomba:~# gluster peer status
Number of Peers: 1

Hostname: kaiserstuhl-svg
Uuid: 5b79b4bc-c8d2-48d4-bd43-37991197ab47
State: Peer in Cluster (Connected)

I have reconfigured default parameters and i try diff algorithm for
self-heal :

toomba:~# gluster volume info all

Volume Name: REP_SVG
Type: Replicate
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: toomba-svg:/storage/backup
Brick2: kaiserstuhl-svg:/storage/backup
Options Reconfigured:
cluster.self-heal-window-size: 64
cluster.data-self-heal-algorithm: diff
diagnostics.client-log-level: WARNING
performance.write-behind-window-size: 1MB
performance.cache-size: 32MB
diagnostics.brick-log-level: WARNING

And i just use this command :
gluster volume rebalance REP_SVG start

And after 2 or 3 days of "fix layout", i always have the same message :
toomba:~# gluster volume rebalance REP_SVG status
rebalance failed

Here are the errors messages :
toomba:~# tail /var/log/glusterfs/etc-glusterd-mount-REP_SVG.log

Please tell me that i missed one option, and you have THE solution...
Because i have try so many parameters, and all the time the replication
failed...

Let me know if you need more information.

Best regards.
