Thanks for you reply! May be another way is a floating IP between two
interfaces with IPVS (corosync).

Different interfaces need to be declared with different LNET networks -
something like networks=tcp0(eth0),tcp1(eth1). Of course, that assumes
your clients are configured to use a mix of tcp0 and tcp1 for connections
(with each client only using one of the two). This is really only useful
in
If you can, I'd advocate the route you suggest - multiple RAID groups,
each group maps to a unique LUN, and each LUN is an OST. Note that
you'll likely want the number of data disks in each RAID to be a power
of 2 (e.g., 6- or 10-disk raid6, 5- or 9-disk raid5). Obviously,
you'll be wasting more
RedHat's OFED tends to lag Mellanox's. They're pretty current on
bugfixes, but support for the latest hardware is usually 3-6 months
behind - it took about 4 months to bring in drivers for our most
recent FDR system. Also, support for Mellanox's advanced features
(e.g., MXM, FCA) is often
We're using 1.8.7.80-wc1 here. It's basically 1.8.7-wc1, but with a
few fixes pulled in from git a few months back to build on rhel6.2.
It's built on top of Mellanox's OFED 1.5.3-3.0.0, and is working just
fine on our FDR14 cluster.

I've had success with LACP bonding, with an LACP-aware switch. You
may also want to check your xmit_hash_policy (it's a kernel option to
the linux bonding driver). I've had the best luck with layer3+4
bonding, using several OSSes with sequential IPs, and striping files
at a multiple of the
Is your ethernet FS in tcp1, or tcp0? Your config bits indicate the
client is in tcp1 - do the servers agree?

FYI, I'm using Lustre 1.8.5 to mount two filesystems from separate
domains (one in Lafayette, IN, and one in Bloomington, IN, run by two
different institutions) on 900+ nodes, and things just work.

What does that imply for sites migrating from 1.8 to 2.1? Presumably
some sites will have both 1.8 and 2.1 filesystems; will those sites
need to run 2.0 on the clients to mount both FS versions concurrently?
