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
