[Lustre-discuss] mv_sata module for rhel5 and write through patch

[Brock Palen]

We are (finally) updating our x4500's to rhel5 and luster 1.8.5 from rhel4 and 1.6.7

On rhel4 we had used the patch from:
https://bugzilla.lustre.org/show_bug.cgi?id=14040

for the mv_sata  module.

Is this still recommended on rhel5? To use the mv_sata module over the stock redhat sata_mv as well as applying this patch?  That patch is quite old is there a newer one?

What are other x4500/thumper users running?

Also I will do some digging on the list but why is lustre 2.0 not the 'production' version? We are planning on 1.8.x for now but if 2.0 is stable we would install that one.

Can we upgrade directly from 1.6 to 2.0 if we did this?
