[lustre-discuss] Questions about upgrading

[Makia Minich]

It's less that it's ext4 or anything; if you're using MDRAID or some 
kind of JBOD or enclosure you'll need to make sure that those devices 
assemble exactly the same. As long as those devices look the same after 
the "upgrade" you'll be ok. For the most part, should be as simple as 
mounting and letting Lustre take it's time to make sure everything is 
ok, though you may need to pay attention to some fsck options 
prior/during the upgrade of the Lustre versions, especially with a jump 
from 2.5 to 2.12, but I'm less of an expert on some of that.
