Description

Hello,
I am a beginner of Lustre.
I meet a very strange problem when I mount combined mgs/mdt file system.
Actually, I have installed all required software before I executed the following commands.
I firstly execute:
mkfs.lustre --fsname=temp --mgs --mdt --index=0 /dev/sdb

and then execute:
mount -t lustre /dev/sdb /mnt/mdt

But I got the error message:
LustreError:11-0: temp-MDT0000-lwp-MDT0000:Communicating with 0@lo, operation mds_connect failed with -11

I have examined all network connection, the connection works find. I don't know why I get this error. Can anyone give a suggestion? Thank you.
