Thanks Nirmal,

tunefs now works, I run this commnad:

/opt/lustre/sbin/tunefs.lustre --ost --erase-param
--mgsnode=192.168.27.252 at o2ib /dev/mapper/home.ost.01
  
but I still cannot mount the OST. After try of mounting OST I've got:

And on MDS:

registration.

Have you got any idea what is wrong? How can I clean the MGS?

Michal.
