Hi Amar, thanks for prompt reply. I've tried space and comma with space between volume names and it didn't work :) is it possible that this option is overriden by some other alu options? I have the following configuration in unify translator: volume unify type cluster/unify subvolumes afr01 afr02 afr03 afr04 option namespace afrns option scheduler alu option alu.read-only-subvolumes afr02,afr03 option alu.limits.min-free-disk 5% option alu.stat-refresh.interval 10sec option alu.order disk-usage:read-usage:write-usage:open-files-usage:disk-speed-usage option alu.disk-usage.entry-threshold 1024M option alu.disk-usage.exit-threshold 32M end-volume if I initiate write operations, I see that afr02 and afr03's underlying file-systems are being used for file storage. 2008/9/5 Amar S.
