Or can I use a varstrip_dist distribution on a directory and set the strip sizes to 0 for servers I don't want to use? Matthieu

So there is no way to associate a particular directory to a particular set of servers, correct?

You might have to specify the layouts explicitly at create time rather than inheriting them from directory hints. -Phil On 06/03/2015 11:56 AM, Dorier, Matthieu wrote: > It does help, thanks! > Matthieu > > ________________________________________ > From: Elaine Quarles [[email protected]] > Sent: Wednesday, June 03, 2015 10:36 AM > To: Dorier, Matthieu > Cc: [email protected] > Subject: Re: [Pvfs2-users] Changing distribution/layout using PVFS API > > Matthieu, > > You can look in the source tree at src/apps/admin/pvfs2-xattr.c for an > example of using the PVFS_sys_seteattr function call to set > attributes. > > Hope that helps! > Elaine > > On Wed, Jun 3, 2015 at 10:56 AM, Dorier, Matthieu <[email protected]> wrote: >> Hi, >> >> I'm reading this page: >> http://www.orangefs.org/trac/orangefs/wiki/Distributions >> Could you give me an example of how to change the layout of an existing >> directory using PVFS_SYS_LAYOUT_LIST and the PVFS API (instead of setfattr)? >> Thanks, >> >> Matthieu >> >> ________________________________ >> Matthieu Dorier, PhD >> Postdoctoral Appointee >> Argonne National Laboratory, MCS >> 9700 S Cass Ave, Lemont, IL 60439 >> +1 630 252 1515 >> >> _______________________________________________ >> Pvfs2-users mailing list >> [email protected] >> http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users >> > _______________________________________________ > Pvfs2-users mailing list > [email protected] > http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
