Just remade a couple of filesystems and received an alignment msg I don't recall receiving previously: # mkfs.xfs -f -d su=64k,sw=12 /dev/s2d_a1l003 mkfs.xfs: Specified data stripe width 1536 is not the same as the volume stripe width 2048 meta-data=/dev/s2d_a1l003 isize=256 agcount=44, agsize=268435440 blks = sectsz=512 attr=2, projid32bit=0 data = bsize=4096 blocks=11709285376, imaxpct=5 = sunit=16 swidth=192 blks naming =version 2 bsize=4096 ascii-ci=0 log =internal log bsize=4096 blocks=521728, version=2 = sectsz=512 sunit=16 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 /dev/s2d_a1l003 is an alias to dm-0 which is a dm-multipath device to a LUN on hardware RAID. The hardware geometry is 64kx 12, 768k. AFAIK no geometry information has been specified for these device mapper devices (someone else's responsibility). Though I assume dm geometry data is the reason for mkfs.xfs throwing this alert. I don't find anything in /sys/devices/virtual/block/dm-0/ indicating geometry. Any ideas how to verify what's going on here and fix it? Thanks, Stan _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
