I was playing around with the 2d-dist last night, and noticed something weird occuring whenever I was trying to set some of the distribution paramaters, I'm not sure if this occurs on other distributions, but I'm also not sure how to test it on other dists, reproducing it requires the following sequence:
( I have /scratch mounted through the pvfs2-vfs, and output for the pvfs2-viewdist's are below) rm -rf /scratch/2d mkdir /scratch/2d setfattr -n "user.pvfs2.dist_name" -v "twod_stripe" /scratch/2d setfattr -n "user.pvfs2.dist_params" -v "strip_size:1048576" /scratch/2d touch /scratch/2d/test pvfs2-viewdist -f /pvfs/4node/2d/test (#1) rm /scratch/2d/test touch /scratch/2d/test pvfs2-viewdist -f /pvfs/4node/2d/test (#2) setfattr -n "user.pvfs2.dist_params" -v "num_groups:3" /scratch/2d rm /scratch/2d/test touch /scratch/2d/test pvfs2-viewdist -f /pvfs/4node/2d/test (#3) (#1) p5l8:/usr/src/gamess-hg# pvfs2-viewdist -f /pvfs/4node/2d/test dist_name = twod_stripe dist_params: num_groups:2,strip_size:1048576,factor:256 (#2) p5l8:/usr/src/gamess-hg# pvfs2-viewdist -f /pvfs/4node/2d/test dist_name = twod_stripe dist_params: num_groups:2,strip_size:1048576,factor:256 (#3) p5l8:/usr/src/gamess-hg# pvfs2-viewdist -f /pvfs/4node/2d/test dist_name = twod_stripe dist_params: num_groups:2,strip_size:65536,factor:256 Notice the strip_size has been reverted back to the default setting of 65536. Any ideas?
