[Gluster-users] Repost: read access to replicate copies

[Rosario Esposito]

Thanks Vijay for your answer.
It's not clear to me how exactly I can use the "read-child" option.
Should I put it somewhere in /etc/glusterd/vols/myvolume/myvolume-fuse.vol ?
Could you please provide some configuration examples ?

Cheers, Rosario
