In case it hasn't been considered yet, shrinking a filesystem can result in terrible fragmentation. The block allocator in resize2fs does not do a great job of handling this case. The result will be a very non-optimal file layout and measurably worse performance, especially for drives with a relatively high average seek time. -- Jon _______________________________________________ OpenStack-dev mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
