Hi all,

I've just upgraded a 1 MDT - 2 OST - 2 Clients - test cluster from
Lustre version to 1.6.6
However, I did not follow the manual (
I did not  use the tunefs.lustre command on MGS/MDT or OSTs.
My data seem to have survived, the quota had to be switched back on with
lfs quotacheck.

My question:  is this treatment with tunefs.lustre ( in particular with
the somewhat scary "writeconf" parameter)  actually necessary at all?
