Nowdays, any data volumes other than root and boot I format xfs. no fsck

I generally use raid10 for data, as my data is usually database oriented 
and raid6(0) performs poorly on committed random writes. raid6 or 6+0 
gets used for large archival 'nearline' applications, like a backup server.

After avoiding lvm for years, I've found its too handy.   the root vg 
will have an adequate sized / and /home and lots of unassigned space, so 
if I need more space for / or /home I can allocate it later.   I tend to 
use dedicated xfs file systems for my database server versus other 
application file storage requirements, these will all be on the data vg.
