[Lustre-discuss] Is using resize2fs on the MDT a supported option?

[Adeyemi Adesanya]

We are are about to install a new Lustre 1.8.2 installation with ~1PB  
of filesystem space. We have to make a decision regarding the MDT  
storage and someone suggested that in the event we run out of inodes  
on the MDT, using resize2fs would be an option (assuming the  
filesystem was created on an LVM partition).

Most of the documentation I have read stresses the importance of MDT  
planning. There is a small mention of resize2fs in the manual but it  
is not clear if this is a robust, reliable technique or if this would  
actually give us more inodes. Should we really be setting up a new  
Lustre installation with the intention of using resize2fs in the future?
