[Lustre-discuss] OST failover

[sd a]

Hi the list,

I have 4 OSS servers , each OSS has 1 gigabit network interface and 2 OSTs,
first OST use /dev/sdb1, second OST use /dev/sdb2.

OSS1: OST1 &  OST2

OSS2: OST3 & OST4

OSS3: OST5 & OST6

OSS4: OST7 & OST8


Each file is striped across 4 OSTs : OST1,2,3,4

And I want to setup failover as:

OST2 failover with OST3

OST4 failover with OST5

OST6 failover with OST7

OST8 failover with OST1


How do I do?

Thanks.
