We're trying to upgrade from HEAD as of 2006-04-15 to 2.6.1. There's little fixes I will check in, but I need some advice on this patch below.
It works around changes to genconfig that went in on 2006-06-10 by slang: http://www.pvfs.org/fisheye/browse/PVFS/src/apps/admin/pvfs2-genconfig?r1=1.54&r2=1.55 We would like to preserve the same handle ranges, and specify on the genconfig command line: --first-handle=4 \ --last-handle=4294967298 \ --root-handle=1048576 \ but the $count in the code as it was, was just data servers. The handle range needs to include metadata servers too. Tell me if this should be handled better than how I hacked around the issue. Turns out it won't matter this time as we have to rebuild the data storage anyway due to the "dir_ent" -> "de" change. There was no warning on server startup about that, though. -- Pete --- src/apps/admin/pvfs2-genconfig 2006-12-19 11:17:04.000000000 -0500 +++ oscbw 2006-12-19 11:28:04.000000000 -0500 @@ -222,11 +222,13 @@ # divide handle range space equally among servers ((2^32)-1 for now) my($total_num_handles_available, $start, $end, $i, $step, $num_ranges); - $num_ranges = $count; $total_num_handles_available = $last_handle - $first_handle + 1; # since meta and data handle ranges must be split, increment # num nodes for calculation purposes below + my @meta_aliases = get_aliases($META_ENDPOINT); + my @io_aliases = get_aliases($IO_ENDPOINT); + $num_ranges = scalar(@meta_aliases) + scalar(@io_aliases); $step = sprintf("%lu",($total_num_handles_available / $num_ranges)); print $target "\n<Filesystem>\n"; @@ -241,7 +243,6 @@ $start = $end = $first_handle - 1; - my @meta_aliases = get_aliases($META_ENDPOINT); @meta_aliases = sort @meta_aliases; foreach my $ma (@meta_aliases) { @@ -253,7 +254,6 @@ print $target "\t</MetaHandleRanges>\n"; print $target "\t<DataHandleRanges>\n"; - my @io_aliases = get_aliases($IO_ENDPOINT); @io_aliases = sort @io_aliases; foreach my $ia (@io_aliases) { _______________________________________________ Pvfs2-developers mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-developers
