zfs discuss - Feb 2006 - Customer questions

A few questions:

   1. How does ZFS compare to Luster?
   2. Is ZFS compatible with Veritas Netbackup Suite?
   3. Does ZFS support bare metal restore (BMR)?

Pointers welcome!!

> How does ZFS compare to Luster?
I don''t know much about Lustre, but it appears to be a cluster file
system.  At this time, ZFS is not.   Sun''s cluster filesystem today is
QFS.
> Is ZFS compatible with Veritas Netbackup up Suite?
To a great extent yes.  I don''t think that Netbackup can backup or
restore ACLs associated with a file though.
> Does ZFS support bare metal restore (BMR)?
I would ask it the other way around.  I don''t know how much BMR does or
can support ZFS.  One point is that today, ZFS is not bootable.  So the root
filesystem is still UFS.  However recreating ZFS pools/filesystems so that they
could be restored might be tricky.  I don''t actually know how BMR does
that for VxVM disk groups.  If it''s just a set of scripts, then it
could be relatively straightforward to reimplement.

AFAIK, Lustre is a parallel file system, perhaps similar
to Sun''s pfs (RIP?)  or QFS.  In any case, ZFS is not currently 
a cluster file system.  NOW is the time to get clustered ZFS 
requirements into the group, see previous threads on this topic.
