[Lustre-discuss] Setting up lustre for backup

[Onane]

Okey. Is there any other way for doing it ?

In my configuration, OST1 has 80GB & OST2 has 80GB. If I gave them same
fsname & mgsnode, I would access 160GB lustre filesystem on client. I want
to use these two volumes like raid 1. That is, how can I configure lustre
filesystem so that OST2 back up OST1 (say. every hour) ?
