[Lustre-discuss] Setting up lustre for backup

[Onane]

Hello,

I installed lustre on three machines (mc0, mc1, mc2)

I configured lustre,
on mc0 as MDT & MGS pair AND OST1,
on mc1 as OST2
on mc2 as client

I want OST2 to be a mirror of OST1. That is, if I copy a file to OST1, it
will also be copied to OST2. OST2 should be a backup for OST1.

Can I do this configuration using default lustre options ? Can it be
accomplished by --failnode directive ? If so, how can I do it

Thanks in advance
