But I apologize if it's a dumb question, but what do you expect to achieve by setting the sector size here? You will be essentially writing the fs image file over the BluRay Filesystem (which IIRC uses UDF), so, the sector size set on your xfs filesystem image won't matter much, unless I'm missing something, which is exactly why I'm asking it :) Cheers > meta-data=/dev/mapper/cr_nombre isize=512 agcount=4, agsize=3054592 blks > = sectsz=2048 attr=2, projid32bit=1 > = crc=1 finobt=1, sparse=0, rmapbt=0 > = reflink=0 > data = bsize=4096 blocks=12218368, imaxpct=25 > = sunit=0 swidth=0 blks > naming =version 2 bsize=4096 ascii-ci=0, ftype=1 > log =internal log bsize=4096 blocks=5966, version=2 > = sectsz=2048 sunit=1 blks, lazy-count=1 > realtime =none extsz=4096 blocks=0, rtextents=0 > > > -- > Cheers / Saludos, > > Carlos E.
