The prompt is as follows:
Meta-data =/dev/sda3 isize = 256 agcount = 16, agsize = 789067 blks
= Sectsz= 512 attr = 0
Data = bsize = 4096 blocks = 12625072, imaxpct = 25
= Sunit = 0 swidth = 0 blks, unwritten = 1
Naming = version 2 bsize = 4096
Log = internal log bsize = 4096 blocks = 6164, version = 1
= Sectsz= 512 sunit = 0 blks, lazy-count = 0
Realtime = none extsz = 4096 blocks = 0, rtextents = 0

5. Modify/etc/fstab
# LABEL =/opt ext3 defaults 1 2
/Dev/sda3/opt xfs defaults 1 1

6. Manually mount
Mount? T xfs/dev/sda3/xfs
