[Lustre-discuss] Help: NIC Changed Error

[Jiawei Zhao]

Hi Amy,

You could try first unmount all ost, mgs, etc, and redo a tunefs on  
each relevant disk:

tunefs.lustre --writeconf --mgs --mdt --fsname=lufs DISKNAME
tunefs.lustre --erase-param --mgsnode=10.0.38.102 at tcp0 --writeconf  
DISKNAME

Best Regards,
Jiawei
