Good Afternoon,

    I'm in the planning stages of a new lustre file system, and I had some 
questions.


1) I've seen it said that ZFS is a good choice for the lustre mdt, as long as 
it is zfs 0.7.x.  Has anyone had that experience?

2) What about the MGT, that seems like it wouldn't have any issues with being 
on zfs.


The system I presently have in mind is two servers hooked up to a jbod, with 
the MDT and the MGT being separate zpools on the jbod.  That way one head to 
run the mgt and one could run the mdt, while allowing both heads to serve as 
the backup for each other.


w/r,
