Package: xfsprogs Version: 3.1.7 Followup-For: Bug #661580 Hi again, I've patched the NBD driver to set the physical sector size. Was way easier than I imagined: ---------------------------------------------------------------------- --- linux/drivers/block/nbd.c~ 2012-03-01 09:10:35.000000000 +0100 +++ linux/drivers/block/nbd.c 2012-03-01 08:57:49.000000000 +0100 @@ -413,6 +413,9 @@ return ret; } + /* Set physical block size to blocksize */ + blk_queue_physical_block_size(lo->disk->queue, lo->blksize); + while ((req = nbd_read_stat(lo)) != NULL) nbd_end_request(req); ---------------------------------------------------------------------- And I can confirm that the sector size detection is still broken in 3.1.7. root@frosties:~$ parted /dev/nbd0 GNU Parted 2.3 Using /dev/nbd0 Welcome to GNU Parted!
