i just created LV, formated it with xfs , extended it , mounted it,
extended the fs , and started to transfer my old /opt to the LV with cpio
there were no complains from mount or xfs_growfs
and i have no the output from mkfs.xfs

[root@svetljo log]# xfs_growfs -n /opt
meta-data=/opt isize=256 agcount=12, agsize=33024 blks
data = bsize=4096 blocks=393216, imaxpct=25
= sunit=4 swidth=12 blks, unwritten=0
= imaxbits=24
naming =version 2 bsize=4096
log =internal bsize=4096 blocks=1200
realtime =none extsz=49152 blocks=0, rtextents=0

That is from /var/log/messages
