[lustre-discuss] confused about mdt space

[肖正刚]

Hello, I have some question about metadata space.

1) I have ten 960GB SAS SSDs for mdt,after done raid10,we have 4.7TB space free.

after formated as mdt,we only have 2.6TB space free; so where the
2.1TB space go ?

2) for the 2.6TB space, what's it used for?
