Good Afternoon,

    I'm in the early planning stages of a lustre upgrade.  We are going to be 
moving from 2.5 to either 2.10 or 2.11, possibly by standing up a new lustre 
file system alongside the existing one and migrating the data over.  I'm 
wondering if anyone has had specific experiences (either positive or negative) 
with either of these versions.


I was also looking for, but couldn't seem to find, a mapping of zfs versions to 
lustre versions.  Am I correct in my assumption that zfs 0.7.9 will work with 
either version?


Finally, does anyone have experience with zfs as the backing for the MDS/MDT?


w/r,
