You can use the mkfs.xfs command to create an XFS file system, for example.
# mkfs.xfs /dev/vg0/lv0
meta-data=/dev/vg0/lv0 isize=256 agcount=32, agsize=8473312 blks
= sectsz=512 attr=2, projid32bit=0
data = bsize=4096 blocks=271145984, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=32768, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
To create an XFS file system with a stripe-unit size of 32 KB and 6 units per stripe, you would specify the su and sw arguments to the -d option, for example:
# mkfs.xfs -d su=32k,sw=6 /dev/vg0/lv1
