[Pvfs2-users] Samba over PVFS2 performance

[jiangyi 60012480]

Hello 
   
    I met a Samba over PVFS2 prolem.So would anybody help me please?
    
    I use the pvfs2 file system and export the files with Samba.The hardware are two JBOD with 146G 10k FC disk, 4 pvfs2 IO servers,8 pvfs2 clients and some windows clients.Every IO server manages 6+1 RAID5.the stripe size is 64k.

    My problem is that How can we tuning the read/write performance of this system ?

    this architecture,I test the performance with 2G files.and find the read performance is fast,but the write performance is bad.Would you tell me what should be care about Samba over PVFS2?
Thank you.

Sincerely,


                                                                 --philips
