Revision 1.14, Mon Apr 28 16:26:35 2008 UTC (9 years, 6 months ago) by dgc.longdrop.melbourne.sgi.com
Fix intermittent failure on 64k pagesize Files are too small for 64k sized I/Os to reliably produce 50 extents +/-10%. Increase the size of the files to increase reliability. Merge of master-melb:xfs-cmds:30996a by kenmcd. Fix intermittent failure on 64k pagesize. |
