Hi,

What RAID level should be used for MDS configuration? The manual seems
to suggest RAID1, however, the FAQ suggests RAID0 level.
http://manual.lustre.org/manual/LustreManual16_HTML/RAID.html#50401396_pgfId-1290495
http://wiki.lustre.org/index.php/Lustre_FAQ#What_is_the_typical_MDS_node_configuration.3F

Also, is it possible to add more OSTs as the requirement grows? If
yes, can additional resources be made part of RAID or can we turn
existing non-RAID system into a RAID system? Any insights?

CS
