[Lustre-discuss] ldiskfs for MDT and zfs for OSTs?

[Ned Bass]

I'm guessing your git checkout doesn't include this commit:

* 010a78e Revert "LU-3682 tunefs: prevent tunefs running on a mounted device"

It looks like the LU-3682 patch introduced a bug that could cause your issue,
so its reverted in the latest master.
