[Lustre-discuss] lustre and multi path

[Brock Palen]

Our new lustre hardware arrived from sun today.  Looking at the duel  
MDS and FC disk array for it.  We will need multipath.
Has anyone ever used multipath with lustre?  Is there any issues?  If  
we set up regular multipath via LVM lustre won't care as far as I can  
tell and browsing archives.

What about multipath without LVM?  Our StorageTek array has dual  
controllers with dual ports going to dual port FC cards in the  
MDS's.  Each MDS has a connection to both controllers so we will need  
multipath to get any advantage to this.

Comments?
