From: snitzer@sourceware.org To: lvm-devel@redhat.com, lvm2-cvs@sourceware.org Subject: LVM2/test t-pvcreate-operation-md.sh Date: Sat, 21 Aug 2010 15:43:00 -0000 [thread overview] Message-ID: <20100821154346.11816.qmail@sourceware.org> (raw) CVSROOT: /cvs/lvm2 Module name: LVM2 Changes by: snitzer@sourceware.org 2010-08-21 15:43:45 Modified files: test : t-pvcreate-operation-md.sh Log message: Verify that pvcreate --dataalignment really does override the topology detected alignment. NOTE: lvm2 doesn't detect MD 1.2 metadata (now the default on RHEL6) so for now I'm forcing 1.0 metadata. This was needed to be able to reuse the existing loop devices but recreate the md device with different raid0 striping.
