[Lustre-discuss] Upgrading major components

[Mag Gam]

Hi All,

I am planning to migrate from 1.6.5.52 (MDS, MDT, OST, OSS) to the
latest stable 1.6.6. The clients are already at 1.6.6. I was wondering
if I should do anything special other than backup my most critical
data. I suppose if I just upgrade my kernel with new lustre support, I
should be just able to mount everything up with no problems.

Also, what would happen if the MDS was only upgraded and not OST volumes?

TIA
