[Lustre-discuss] 1.6.5.1 <-> 1.6.6

[Jerome, Ron]

For what it's worth, I've upgraded through every version of the Lustre
1.6.x series starting at 1.6.0 and now running 1.6.6 on a production
cluster (32TB in size with 5 OSS's 15 OST's and one MDS/MDT) and I have
never once ran tunefs.luster.... during the upgrade process.
