Hello,

I plan to upgrade both my MDS and OSS server which are now RHEL72 Lustre
2.8.0 + ZFS 0.6.5.8 to RHEL73 Lustre 2.9.0 and ZFS 0.6.5.9.
I plan to first upgrade the MDS then the OSS server.
Is there any risk to lose data ?
My idea was to shut down lustre and upgrade the operating system and
then ZFS. Then upgrade lustre.
Any hint is appreciated.
thank you very much.

Rick
