[Lustre-devel] tunefs.lustre before mount

We're actually trying to get rid of tunefs.lustre for setting config parameters, since it complicates the configuration code, and only has a very limited amount of space.

That said, it should be safe to do repeatedly, though I don't think it has ever been tested.  On the flip side, lctl conf_param does have a limit on the number of parameters that can be set before the configuration has to be reset.

Cheers, Andreas

Assuming I can get access to all the "correct" parameters, would there be a reason that performing a tunefs.lustre before each mount would be harmful?  It's the most straightforward way I can think of to force Lustre to have the correct configuration (ib addresses, etc.) at all times.

I don't think it should be an issue, I was just wondering if anyone had run into problems repeatedly running tunefs.lustre (1000s of times against each target)
