[Gluster-users] using a preferred node ?

[Mathieu Chateau]

Hello,

sorry to bother again but I am still facing this issue.

client still looks on the "other side" and not using the node declared in
fstab:
prd-sta-sto01:/gluster-preprod /mnt/gluster-preprod glusterfs
defaults,_netdev,backupvolfile-server=prd-sta-sto02 0 0

I expect client to use sto01 and not sto02 as it's available.

If I add a static route to break connectivity to sto02 and do a "df", I
have around 30s before it works.
Then it works ok.

Questions:

   - How to force node to stick as possible with one specific (local) node ?
   - How to know where a client is currently connected?

Thanks for your help :)
