[Lustre-discuss] Lustre 2.2 production experience

[Marek Magryś]

Hi Wojciech,

We have been using 2.2 in production on 500TB fs with 8 OSS and >1k 
clients for some time, but we are now in process of rolling back to 
2.1.1 on the clients, as there are some critical bugs which force us to 
do so. However we plan to stay in 2.2 on the servers for as long as 
possible (until we hit some bug).
I'd advise not to go for 2.2 on the clients at the moment, however 
servers seem to work fine - but this is just my personal opinion, I bet 
that Whamcloud guys can tell you more as they have a wider look at all 
bugs status.

Cheers,
Marek
