Lucas, I think the overhead of putting it on to a different node will not show any performance gain. This includes the network traffic to your MySQL server rather then using a socket on the localhost.
If you are trying to improve performance, have you tried using multiple cores with RBH? Some tuning that Thomas showed are here: http://sourceforge.net/apps/trac/robinhood/wiki/TunePipeline You can also optimize MySQL with mysqltunner.pl > Node1: robinhood --scan --once -f myconf -L stdout -F /A/B > Node1: robinhood --scan --once -f myconf -L stdout -F /A/C > Node1: robinhood --scan --once -f myconf -L stdout -F /A/D If you just want to scan parts of your filesystem, have a unique myconf file that includes an Ignore block FS_Scan { # FS Specific Ignore { not tree == "/A/B" } } Do this for each of your folders on your filesystem. Does that help? -Adam -- Adam Brenner Computer Science, Undergraduate Student Donald Bren School of Information and Computer Sciences Research Computing Support Office of Information Technology http://www.oit.uci.edu/rcs/ University of California, Irvine www.ics.uci.edu/~aebrenne/ [email protected] On Mon, Jan 13, 2014 at 11:09 PM, Lucas <[email protected]> wrote: > Hello, > I have a thought in my mind that running robinhood in multiple nodes > to scan the file system. first step is to split the file system into many > sub-filesystem(I have find a way to implement it ), then run robinhood in > many other nodes and update the ENTRIES table of MySQL database. > I tested the -F parameter, here we surpose the structure of the > database is: > /A > |-- B > |-- C > |-- D > And there are three nodes using robinhood to scan the the file system: > Node1: robinhood --scan --once -f myconf -L stdout -F /A/B > Node1: robinhood --scan --once -f myconf -L stdout -F /A/C > Node1: robinhood --scan --once -f myconf -L stdout -F /A/D > Apparently it is not works, but what if modified the source codes of > list_mgr and only update the ENTRIES table ? > Is that a good idea? > > Best regards, > Lucas > > > > ------------------------------------------------------------------------------ > CenturyLink Cloud: The Leader in Enterprise Cloud Services. > Learn Why More Businesses Are Choosing CenturyLink Cloud For > Critical Workloads, Development Environments & Everything In Between. > Get a Quote or Start a Free Trial Today. > http://pubads.g.doubleclick.net/gampad/clk?id=119420431&iu=/4140/ostg.clktrk > _______________________________________________ > robinhood-devel mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/robinhood-devel > ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
