Nowdays, any data volumes other than root and boot I format xfs. no fsck or > 16TB problems there. 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. -- john r pierce 37N 122W somewhere on the middle of the left coast
