xfstests 279: mkfs.xfs: properly handle physical sector size
Last modified: 2013-02-21 06:00:54 EST
Description of problem: Use this bug to track the following xfsprogs commit commit 287d168b550857ce40e04b5f618d7eb91b87022f Author: Eric Sandeen <sandeen@sandeen.net> Date: Thu Mar 1 22:46:35 2012 -0600 mkfs.xfs: properly handle physical sector size This splits the fs_topology structure "sectorsize" into logical & physical, and gets both via blkid_get_topology(). This primarily allows us to default to using the physical sectorsize for mkfs's "sector size" value, the fundamental size of any IOs the filesystem will perform. We reduce mkfs.xfs's "sector size" to logical if a block size < physical sector size is specified. This is suboptimal, but permissable. For block size < sector size, differentiate the error message based on whether the sector size was manually specified, or deduced.

I'm happy to fix this if/when xfsprogs gets an update.
This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux.
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
QE has got no problem testing this for rhel-6.4.
Going to include another related patch: commit 66bd6431d0e3b3618c8abacbd6df3fbae74abeec Author: Carlos Maiolino <cmaiolino@redhat.com> Date: Tue Dec 6 14:45:18 2011 -0200 mkfs: refuse to initialize a misaligned device if not forced using libblkid This is a new version of a patch to fix the problem about the usage of 4k sector devices when the device is not properly aligned. It makes mkfs to refuse to initialize a xfs filesystem if the -f option is not passed at the command line, and forces a 512b sector size if the user chooses to force the device initialization. Signed-off-by: Carlos Maiolino <cmaiolino@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de> both for simpler porting and because it's solving related problems.
