Hi Harshavardhana, thank you for your reply. i will use the performance options for samba. to your questions:
volume web-data-replicate type cluster/replicate subvolumes gfs-01-01 gfs-01-02 end-volume volume readahead type performance/read-ahead option page-count 16 # cache per file = (page-count x page-size) subvolumes web-data-replicate end-volumewhat is the client side and server side TOTAL ram ?. How many servers and clients do you have?. Coz having read-ahead count on 16 is no good for an ethernet link, you might be choking up the bandwidth unnecessarily.
we have 2 physikal xen server and 2 physikal gfs-server (one gfsserver with 48TB space - 24 x 2TB SATAII) we use on xenserver 14 domUs alle domUs are located on glusterfs. And now we try to share in domU1 another gfs-lun (gfs-partition) via samba each of the physikal xen server have 2x Quadcore with 12GB ram each of the physikal glusterfs server have 2x Quardcore (hyperthreading) with 12GB ram xen - domU1 has 1 CPU and 2GB ram and shares another gfs-lun via samba
Even with this we would need to know the backend disk performance with o-direct to properly analyse the cost of using buffering on server side to get better performance out of the system.
