[Gluster-users] unable to get Geo-replication working

Mon Apr 30 16:36:10 UTC 2012

Sure.... although if you read my original post I already tried this.

[root at retv3130 rets5030]# ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no -i /etc/glusterd/geo-replication/secret.pem hptv3130 "ls -ld /nfs"
setterm: $TERM is not defined.
drwxrwxrwx 2 root root 4096 Apr 26 16:06 /nfs

Okay... so can you try the following:

# ssh -oPasswordAuthentication=no -oStrictHostKeyChecking=no -i
/etc/glusterd/geo-replication/secret.pem hptv3130 "ls -ld /nfs"
